MRI- An Imaging Study To Diagnose The Diseases

Magnetic resonance imaging is a modern method for studying the structure, condition, and function of internal organs. It is based on the measurement of electromagnetic waves emanating from body tissues. These signals are transmitted to a computer, which decodes them and converts them into an image. The obtained data is analyzed and evaluated by a specialist conducting an MRI.

Modern equipment allows obtaining a three-dimensional image of the internal organs so that the study has high information content. MRI helps to identify a large number of diseases that are not so accurately diagnosed using other methods.

MRI has great advantages over invasive and radiographic methods, as it is a safe and comfortable procedure. Due to this, the study is used in the diagnosis of diseases of many organs and systems:

  • Brain;
  • Vessels of the neck and brain;
  • Jaw and temporomandibular joint;
  • Joints;
  • Spinal cord;
  • Spine;
  • Abdominal organs;
  • Pelvic organs;
  • Respiratory system;
  • Endocrine system;
  • Lymphatic system;
  • Reproductive system.

One of the most common areas of magnetic resonance imaging in the diagnosis of diseases of the nervous system. MRI of the brain allows detecting tumors and determining the stage of their development, diagnosing problems with vessels, multiple sclerosis, and other pathologies.

Many patients are interested in - with MRI of the brain, radiation occurs, and is it dangerous? What dose of radiation does the body receive during the research? Is MRI Hazardous to Health?

MRI Radiation Level

Unlike X-rays and computed tomography (CT), patients receive a zero dose of radiation during an MRI scan, since this study is not based on ionizing radiation, but on electromagnetic effects.

The effect of a magnetic resonance imager is comparable to that of a cell phone or microwave. MRI done by MRI test labs in Delhi does not cause irregularities in the structure, condition, and function of tissues and organs, being at the same time a highly accurate diagnostic method.

Therefore, you can be sure that there is no radiation during an MRI scan of the brain.

Magnetic resonance imaging in oncopathology?

Patients with oncologic MRI are prescribed with the use of a contrast agent - to increase the information content of the study: this allows a detailed study of the tumor and its vascular network. Due to the high precision and diagnosis, the most effective treatment is prescribed.

The absence of irradiation provides the possibility of using MRI for cancer patients with confirmed diagnoses of various malignant tumors, which are not recommended for X-ray methods. X-ray and computed tomography due to ionizing radiation harm the tissues of the body: cause changes in DNA and adversely affect the already existing pathological processes. Electromagnetic effects during MRI are safe for both tumors and healthy tissues and organs.

How often can I do magnetic resonance imaging?

In the absence of contraindications, MRI may be prescribed - depending on the disease and the characteristics of its course - as often as necessary to develop an effective treatment plan or to correct it. Since the procedure is safe for the body, it can be carried out with a minimum time interval.

The frequency of an MRI can only be determined by a doctor. If there is an urgent need or in accordance with the developed plan of dynamic observation, the study is carried out several times in one day.

Is It Possible To Do CT And MRI For Children?

Imagine that a doctor prescribes your child to undergo a computed tomography or magnetic resonance imaging. Most likely, you are, first of all, thinking about the possible risks: will this or that research harm the children's organism? How will the child take them?

Is there a danger?

Magnetic resonance imaging (MRI) is an absolutely safe method of research, since it does not use ionizing radiation sources. There is no reason to worry about the hypothetical harm to the child from this type of diagnosis. When conducting computed tomography (CT), X-rays are used, so the concerns of the parents are well founded. But in the medical organizations of the Moscow Department of Health, special pediatric research protocols are used, which allow reducing the radiation dose to the minimum harmless values. Therefore, this procedure does not have any negative impact.

Is it possible to replace a CT scan with a safer MRI?

MRI and CT are two different methods of radiation diagnosis, which are not always interchangeable. They give different information about the state of health, so the question of what kind of research to conduct a child is decided directly by the attending physician or radiologist. The greatest harm to health is caused not by a microdose of X-rays, but by insufficient diagnostics.

Is it necessary to give children anesthesia during CT and MRI?

During CT and especially MRI, it is very important that the child remains stationary throughout the procedure; otherwise, the results will not be accurate or not suitable for analysis. The MRI procedure takes an average of 20-30 minutes, which means that the child will have to lie motionless all this time. As practice shows, children 5-6 years and older do an excellent job with this task. But earlier patients are difficult to maintain immobility.

For children under 3 years old, CT and MRI are performed only in a hospital, under the supervision of specialists. Before the study, the child is given a sedative or mild inhalation anesthesia, after which he wakes up quickly and easily.

CT and MRI with contrast enhancement

To diagnose some diseases, a child may need to have a CT scan or MRI with a so-called contrast - and you should not be afraid of this study. Before the procedure, the doctor will carefully collect anamnesis and find out all about possible contraindications. For greater safety, a study with contrast enhancement in children is carried out only in hospitals.

Where will my child be taken for CT and MRI?

According to the order of the Moscow Department of Health, the routing of children on CT and MRI in hospitals is carried out in accordance with the assignment by the district. That is, depending on the CT scan centre in which you are monitored, you will be assigned a referral to one or another institution.

In most cases, children under 3 years old are sent to inpatient medical organizations for CT and MRI. This is due to the need to introduce anesthesia for the success of the study. Children over 4 years old can undergo an outpatient study.

How Essential Oils Can Prevent Migraine?

Migraine is a severe recurring vascular headache. More often than not, it is women who suffer more from this medical condition than woman. The dull ache is often heart throbbing and in some cases distorts the speech of a person due to the severity of pain. Only a detailed scan of the head in the MRI Scan Centre can give the right assessment of the pain.

Though migraine does have specific medications in place for every possible level of pain, the essential oils can also have a significant impact in easing the pain. One may ask how the essential oil can be as good, if not better than the drugs and medication. To put things into perspective, the essential oils are administered externally. On more beneficial terms, the essential oils provide relief, aid circulation and reduce stress. They are equally laced with other health benefits like boosting your immune system instead of wreaking havoc on your vital organs. Let's have a look at some of the essential oils which are effective in preventing migraine.

  1. Peppermint- It has a long-lasting cooling effect on the skin, ability to inhibit muscle contractions and role in stimulating blood flow in the forehead when applied topically. One suggestion to use peppermint oil to improve blood circulation, reduce pain and relieve tension is that the oil be diluted with two to three drops of peppermint oil with coconut oil and applied into the shoulders, forehead, and back of neck.
  2. Lavender- Lavender essential oil has a variety of therapeutic and curative properties. It has excellent properties which relax and relieves tension and stress — working as a sedative, antidepressant, anti-anxiety, anxiolytic, anticonvulsant and calming agent. It can even be an effective treatment of neurological conditions and disorders, the latest research shows. The two primary benefits of lavender oil are relieving feelings of restlessness and disturbed sleep, two symptoms of headaches. It also regulates serotonin levels, which helps minimize pain in the nervous system that can lead to migraine attacks
  3. Eucalyptus- Widely regarded as an expectorant, it helps cleanse the body of toxins and harmful microorganisms. It also opens the nasal airways and eliminates sinus pressure that can lead to a nasty headache; all while promoting emotional balance and boosting mood. To get quick relief, add diluted two to four drops of eucalyptus oil with carrier oil, and apply it topically to the chest, back of the neck, temples, and forehead. Not only does it eliminate the nasal buildup and clears your airways — alleviating the sinus tension that leads to a headache or migraine attack.
What Are The Various Applications Of MRI Testing?

Medical resonance imaging or MRI is a common examination that allows you to explore the inside of the body with precision. Compared to conventional radiology, MRI allows to perfectly visualize most abnormalities, malformations or tumors present in a tissue. The images have quality much higher than radiography called "banal", but this quality of images still remains lower than that of the scanner. We will use MRI for organs or tissues that have more water, which will allow a more accurate diagnosis, especially between infections or tumors. It can be differentiated thanks to the different shades offered by the MRI done by MRI Scan Centre.

1. Breast MRI.

In recent years, breast cancer screening has been favored thanks to MRI. Indeed, this being sensitive, it obtains results very favorable to "this exercise". According to an American researcher, MRI may even be superior to mammography when screening for breast abnormalities. The MRI can also tell if the abnormality needs to be treated or not.

2. Brain MRI

MRI is mainly used to detect abnormalities in the blood vessels in the brain, but also to detect abnormalities in the brain itself. MRI allows different sections (transverse, longitudinal or oblique) to be made. Whenever possible, try not to inject contrast medium. Gadolinium (contrast medium) is exclusively used for MRI because it is injected by "intravenous". The detection of malformation of the brain structure, or abnormalities of its contour are in most cases detected. The advantage is that it allows in addition to detect its origin, as well as its nature (vascular, degenerative, tumoral, inflammatory, or infectious).

3. Bone or ligament MRI

When MRI is used for this type of "problem", it can be noted that it is often for back problems (vertebrae) that patients come for an MRI. Experts have told us that these patients made up two-thirds of the bone or ligament MRI.

4. Hepatic MRI

The main studies of this MRI are the anatomy, as well as the vascularization of certain organs, more particularly the liver, subject to abnormalities such as cancer, angiomas (malformation of the vascular system of the liver), or the adenoma (tumor benign (non-cancerous) due to the proliferation of a normal glandular tissue). A contrast product is specifically dedicated to the liver, ferrite because it is iron-based.

5. MRI in the future.

Derivatives have emerged such as MRI, which is functional magnetic resonance imaging. This new technique allows the study of the specific functions of the brain that intervene in the execution of these different tasks (taste, smell, and reading, listening). This replaces more and more PET: positron emission tomography (positive electrons) which uses radioactive tracers to detect cognitive activity (the intrinsic intellectual activity of the brain). Unlike PET, which can only be used once on the same patient (because of positron irradiation), MRI can be done several times because the marker is blood oxygenation which is a natural phenomenon of the body and that there is no radiation emitted on the patient.

IUD and Magnetic Resonance

Magnetic resonance imaging (MRI) is a test that is done on a large device that uses a magnetic field and energy pulses of radio waves to make pictures of the organs and structures inside the abdomen. In many cases, MRI test in east Delhi provides information about body structures that cannot be seen as well with an x-ray, ultrasound or computed tomography (CT) scan.

To start with, it is worth recalling that an IUD is an intrauterine device made of T-shaped plastic that is usually covered with copper. The IUS is a device, similar to the IUD, adding the function of releasing hormones containing levonorgestrel to prevent pregnancy. The IUD / IUS must be implanted inside the woman's uterus through the vagina, is a fast and straightforward procedure. It is the most frequently used reversible contraceptive method in the world.

Most IUDs are composed of plastic with copper wire or fixed with copper strips, while some also have a central core of silver to prevent the fragmentation of copper, and even some minimal part composed of stainless steel. Tests performed, evaluating the interactions of the magnetic field and the heating of the IUD in 3.0 Tesla’s equipment indicate that these objects are safe for patients, not suffering any displacement, artifact or heating.

The IUD is made from non-metallic materials that include polyethylene, barium sulfate (i.e., which makes it opaque to radiation), and silicone. Therefore, it is safe for patients undergoing MRI tests in all intensities of static magnetic fields.

All the publications, reports, studies and articles used for the publication of this entry show that the performance of Magnetic Resonance tests in women carrying an IUD / IUS is safe. There is no risk of movement or displacement of the IUD if a woman with an IUD undergoes an MRI.

However, it is recommended by MRI scan centers in East Delhi that, before performing the MRI, the technician is informed that he/she will perform the test of being an IUD carrier.

If you are interested in whether it is possible to do an MRI with crowns, you need to understand that mainly inert metals are used in dentistry. They do not respond to a magnetic field. Is it possible to do MRI with crowns, if you plan to examine the spine or joints of the arms and legs, pelvis, abdomen? Of course, yes, in this case, the metal will not be affected.

If the crowns are made of gold, copper alloys or steel with gold plating, the images are obtained with certain interference. Therefore, if the patient was engaged in the installation a long time ago when these materials were the most popular, the answer to the question “Is it possible to do MRI with crowns?” Is an answer, but the quality of the images may be poor.

What are the Specialized Diagnostic Images for?

The diagnostic imaging tests that apply X - rays have been with nuclear medicine, the largest source of general population exposure to natural radiation in non- Western countries in recent decades. The introduction of new diagnostic techniques such as computed tomography (CT) has rapidly increased the number of doses of ionizing radiation received, with significant consequences not only for the individual patient but also for the total population. The burden of disease caused by excess radiation can be considered as a relevant public health problem that could be prevented.

Efforts have been made both from the FDA to reduce this exposure. Among them, they are:

-          Promotion of the use of safe medical tests, through the establishment of requirements for companies that develop image tests

-          Introduction in MRI Scan Centres in Noida of quality practices and accreditation systems, and recommendations for the establishment of reference doses for each type of test;

-          Quantification of exposure of the general population to radiation derived from medical tests;

-          Creation of a record of the history of the dose of radiation received from each patient, which could help in decision-making;

However, many of the strategies designed do not include the participation of the patient, when they should assume more responsibility in the decision to submit or not to an imaging test taking into account the potential risks as well as the benefits. If the objective is to establish useful recommendations aimed at reducing exposure to radiation, it is necessary to involve all the actors involved, not only the health professionals and companies that develop the technology, but also the patient who will undergo this test.

The inclusion of the patient in decision making is carried out through informed consent. However, its format and the procedure in which it is applied may have limitations in the implication of the patient's co-responsibility. It is essential to know how the population reacts to this radiological risk information, and on the other hand, to see the opinion of the doctor about the best way to inform the patient and what kind of information should be provided.

That is, knowing the attitudes of physicians and patients before the communication of risk/radiological benefit can be an essential factor for the incorporation of procedures in clinical practice that include co-responsibility doctor-patient and lead to the rational use of imaging tests.

Computed tomographies and magnetic resonances are available to physicians to be able to diagnose inappropriate way pathologies that affect the internal organs and tissues of their patients' bodies. The diagnosis of diseases is increasingly specialized and accurate in the world. Thanks to the technological advance in the medical field, achieved in the last decades, it is possible to evaluate in detail each organ and tissue of the body and, through specialized diagnostic images, and detect any anomaly that may occur in them.

The decision of which examination should be performed on each patient depends on various factors that are evaluated by both the attending CT scan centre and the radiologist. These specialists take into consideration, among other things, the type of tissue of the organs they want to analyze, the level of detail required, the characteristics and clinical history of the patient, their age and the general state of health.

Hence the importance of having, not only with high-quality equipment but with doctors highly specialized in radiology who can determine the needs of each patient and make the best possible use of the available machines. A good part of the success of the method of diagnostic images for the detection of diseases is in the interpretation by the experts of the results that the teams produce.

What is MRI or Magnetic ResonanIe Imaging?

The principle of MRI is based on the phenomenon of nuclear magnetic resonance. The organs are analyzed using a powerful magnet in which electromagnetic waves circulate. These high-frequency waves applied to a part of the body return a signal re-emitted by the hydrogen atoms contained in the organs. It is, thus, possible to determine the chemical composition and hence the nature of the tissues.

We obtain a 2D or 3D image of a part of the body. MRI does not irradiate, and it does not emit X-rays.

Magnetic resonance imaging is one of the modern and most informative diagnostic methods that enables specialists to accurately study the internal organs and systems of the human body. The study is widely used in the world in medical practice.

MRI is used to detect various abnormalities and acute illnesses. This non-invasive diagnostic method allows you to visualize in detail even deep tissue. The study makes it possible to obtain a layered image of internal organs. At the same time, the quality of tomography images is comparable to real photos of anatomical sections.

What is an MRI?

Magnetic resonance imaging is considered a safe method of investigation since it does not have radiation or ionizing radiation on the patient. Therefore it is harmless to the body. As the name suggests, this diagnostic method is based on the phenomenon of nuclear magnetic resonance.

To understand what an MRI scan discount is, you need to have an idea of how it works. The essence of the technique is that the nuclei of some atoms placed in a magnetic field can absorb electromagnetic pulses. In the future, they convert the energy into radio signals and, after the end of the pulse, radiate them.

Tomographs used in medicine work on the nuclei of hydrogen atoms that make up water molecules, of which the human body is 70%. The amount of fluid in different organs of the body is different, as a result of which during the scan the tissues radiate different signals. Thanks to this, the MRI device can accurately:

  • Visualize internal organs;
  • Distinguish healthy cells from pathological;
  • Identify any violations of the work of the bodies.

This is a unique method of diagnosis, which allows specialists to obtain high-quality images of virtually all structures of the human body. MRI-examination especially accurately and in detail visualize soft tissues, joints, and cartilages. An innovative technique enables physicians to make images of structures that are difficult to obtain by other methods of research. Such hard-to-reach tissues include those that are located near the bone structures, for example:

  • Intervertebral discs;
  • Spinal cord and brain;
  • Inner ear;
  • Pelvic organs;
  • Ligamentous apparatus.

However, images of structures containing a small amount of water are less accurate in perceptions. Therefore, for examination of the lungs or bones of the skeleton, magnetic resonance imaging is rarely used.

Why And When You Need To Have MRI Scan?

In today’s world, there are different types of medical examinations done with the help of multiple devices so that doctors can get the best result and offer the accurate treatment to the patients. MRI Scan is one such examination that is done to determine different health conditions of a patient and plan the future treatment process.

What is MRI Scan?

Magnetic resonance imaging or MRI scan is a radiological technique. In this method radio waves, magnetism and a computer are used to create the images of the body structure of the patient. The scanner looks like a large tube which is surrounded by a huge circular magnet.

There is a moveable bed on which you as a patient need to lie down and then that bed will be inserted into that tube which is surrounded by a magnet to get the images.

Why Do You Need MRI Scan?

This is an advanced and sophisticated ways to determine the causes of your certain health issues and helps the doctors to find the right solution for the same.

What Can Be Seen Through MRI Scan?

There are a number of things that can be diagnosed with the help of a successful MRI Scan. The doctor will suggest you to scan a relevant sector to identify the issues in that particular part of your body.

•    Ailments of the brain including dementia and brain tumors

•    Vascular abnormalities

•    Spinal injuries and related ailments

•    Sports injuries

•    Female pelvic problems

•    Prostate issues

•    Some typical gastrointestinal tract issues

•    Certain ENT conditions

•    Bone ad soft tissue conditions

That means a wide range of health issues can be diagnosed with the help of proper MRI scan. However, you need to go to a reputed and experienced pathology center where you can have the best MRI scan done by the experts in this field.

Who Should Not Have This Test?

Certain individuals should not go through this test because of the presence of powerful magnetic force in the scanner. Though your doctor will know better and will not let you have this test, but you should also be informed of the fact that when you cannot have an MRI Scan. You cannot have this test if you have

1.    A cochlear implant

2.    A cardiac pacemaker

3.    Certain clips inside your head due to brain operations

4.    Any kind of metallic foreign body inside your eyes

5.    Had any kind of surgeries within last eight weeks

6.    If you are carrying a baby

In such conditions, you will be considered as not fit for going through an MRI Scan in any circumstances.

Preparing For This Test

There is no need to some special preparation for this test. You need to change your regular clothes and have to wear a gown before you lie down on that bed for the test. Since magnets are used in this test; hence, you have to remove any kind of metal from your body; even your credit and debit cards too.

However, sometimes the patients are given intravenous (IV) contrast liquid injection to get a clearer image of particular body tissues.
