How To Get Your Organs Examined With MRI?

We work, spin in the whirlpool of daily affairs and forget about our health. And then a headache, we try not to pay attention to the first symptoms, etc. And when our body puts us unconscious in the middle of the working day, we finally dare to go to the doctor. Doctors do not make eye diagnoses now and recommend an MRI test in east Delhi first.

The most popular and informative method of examination is MRI (magnetic resonance imaging). But any person, before lying under the watchful eye of magnets, has a lot of questions.

MRI is most often used to study the organs of the central nervous system, spine and musculoskeletal system, internal organs. These studies allow us to assess the structure of organs and its disorders, to identify developmental disorders, traumatic changes, tumors and more.

The method of magnetic resonance imaging (MRI) is one of the most modern and informative diagnostic methods without the use of X-rays, often acts as the instance that allows you to correctly and objectively diagnose. A detailed MRI image allows doctors to detect the smallest signs of the disease.

With the help of MRI, you can get images of almost all body tissues, conduct research in any plane, and if necessary - to obtain three-dimensional images to accurately assess the relationship of different structures.

The use of contrast enhancement increases the informativeness of MRI, but the advantage of high-field devices is the ability to obtain high image quality without the use of contrast agents, which is more cost-effective and safe for patients.

A wide range of diagnostic coils allows you to make a complete examination of the patient, any organ.

Since the method of magnetic resonance imaging does not carry radiation exposure, it is completely harmless to the human body and allows you to repeat the study as often as needed in each situation.

MRI is most often performed under the direction of a doctor or an MRI test lab in Delhi, indicating the area of ​​the study, diagnosis (clinical problem) and purpose of the study. Given the safety of the method, it is possible to examine, including for prevention, at the patient's discretion. You and your doctor should agree in advance on the date and time of the study.

For the correct interpretation of the images obtained by the radiologist before the study, it is desirable to provide available clinical information - an extract from the medical history, as well as data from previous CT or MRI examinations of the doctor who conducted the study.

When you can save and do only CT, and when you cannot do without MRI

Computed tomography is really cheaper than MRI. CT uses X-rays, which better "see" bone structures. Therefore, if you are injured, this method is ideal. In addition, the CT scan clearly shows fresh bleeding from injuries to the head, chest, abdomen and pelvis.

With more complex diseases, you will have to go for an MRI. Especially when it comes to the brain. Therefore, the method is indispensable in neurosurgery and neurology (old brain injuries, strokes, suspected spinal cord and brain tumors, etc.).

The Reason Why MRI Scan Is So Noisy

It is not debatable that MRI scan has been one of the most reliable and best tests for getting diagnosis of multiple ailments and to obtain images of the internal organs of the body. But the question remains why the test procedure or the equipment for that matter is so noisy. So let us figure out.

The Magnetic Resonance imaging machine is basically composed of a powerful magnet, mostly superconductors, with a transmitter and a radio wave receiver, in addition to all the electronics needed to coordinate its operation. It is the reason why the magnet creates a powerful magnetic field even more powerful than that of the earth, the transmitter, in turn, emits radio waves that are directed towards the patient. These waves activate the protons of the different tissues and the receiver picks up the emitted signal with which will create the image.

The MRI machine has four magnets, one main, the largest and most powerful, and the other three smaller ones are the gradients. These smaller ones are inside a large metal coil called the gradient coil. The gradient coil is made of copper electromagnets that create a secondary magnetic field in each of the three directions of space and fulfil a fundamental function since they are responsible for spatially locating the Magnetic Resonance signal and encoding it to create the image that is performed by MRI scan centre in East Delhi.

Why so much acoustic noise? To generate the magnetic field an electric current has to be applied and when it is applied in the presence of a static magnetic field they produce variable magnetic forces that act on the gradient coil (mechanical vibration) and causes it to expand and contract rapidly in a matter of milliseconds producing movements or vibrations generating the noise that is manifested throughout the room, so we can say that the main reason the noise generated by the RM machine present in the MRI test labs in Delhi are the gradient coils.

There are other factors that contribute to generate noise such as the modification of acquisition parameters, acoustic noise tends to improve with the decrease of the thickness of cut, the field of vision (FOV), TR (repetition time) and TE ( echo time) but this may affect the resulting image.

On the other hand, the characteristics of the acoustic noise have a spatial dependence depending on the position and the size of the patient the levels can vary in about 10dB.

Studies conducted including a variety of pulse sequences where several gradients are applied resulted in this type of sequence (3D and GR) being among the strongest with levels ranging from 103 - 113 dB. Other studies also measured the acoustic noise generated by the echo-planar (EPI) and the FSE (fast spin-echo) sequences in 1.5T, noise levels ranging from 114 to 115 dB and at 3T levels in the range of 126 to 131 dB for these noise levels the use of hearing protection is recommended.

General Electric GE developed a technology called Silent Scan a few years ago that allows to reduce acoustic noise to a level similar to that of ambient sound, if we take into account that an RM scanner without this technology generates a noise of approximately 100 dB, depending on several factors, this decrease of almost 30 dB causes greater patient satisfaction and generates a more pleasant silent and comfortable experience.

How To Detect Alzheimer's Early?

Alzheimer's is very high in the ranking of diseases that concern society. Every day more people turn to search engines like Google to find more information on this type of senile dementia.

 What is Alzheimer's disease?

The first definition of Alzheimer's states that it is a type of dementia in older people. There are others such as Parkinson's, vascular or multi-infarction.

In this case, the abilities to develop a normal life disappear, starting with memory, thought and language, and progress slowly until forgetting family members, how to write and read, or patients becoming more nervous or aggressive.

This disease, without cure, usually appears from 60 years onwards and the probabilities are higher when there are cases of other relatives who have suffered from it. One can undergo MRI test from MRI scan center in new Delhi to diagnose the severity of Alzheimer’s disease.

 Alzheimer's Causes:

There are several risk factors that influence the appearance of this type of senile dementia that is important to know for early detection:

•The genetic influence causes that they increase between 2 and 4 times the probabilities that a person with a relative with Alzheimer's suffers from the disease as well.

•As people's ages advance, the possibilities also grow. With 65 years the risk is 10% while with 85 the probability grows to 50%.

•Health problems affect the appearance of pathology such as head trauma or long-term arterial hypertension.

•Unhealthy habits related to sedentary lifestyle, eating and smoking also have a negative influence.

Alzheimer symptoms

There are various signs in people that indicate the possible existence of Alzheimer's, and here are some of them to anticipate the disease:

  • Decreased memory that affects daily life.
  • Difficulty planning and solving numerical problems.
  • Daily household chores, work, and free time become more complicated.
  • Disorientation in time and space.
  • Vision problems sometimes occur in people with Alzheimer's.
  • Problems with the use of language such as forgetting how to say a word.
  • Loss of initiative, good judgment and good humor.

Alzheimer's stages

Alzheimer's can be divided in two ways. On the one hand, in the mild, moderate and severe phases, and on the other hand, on the GDS scale (Global Deterioration Scale). Unifying both classifications, the stages of the disease would be as follows:

  • The emergence of the mild phase in which the first symptoms of the disease occur coincides with GDS3 and GDS4. At that time, slight memory loss occurs, disorientation in unfamiliar environments, difficulty in performing complex tasks due to lack of concentration, but the behavior is totally normal in familiar environments, with family and with habitual friends. The diagnosis of dementia occurs at this stage.
  • In the moderate phase, GDS5 and GDS6 are given, times when performing certain daily activities such as dressing, eating, washing, or controlling bowel movements become complicated for patients.
  • The severe phase corresponds to GDS7 and in it the Alzheimer patient is cognitively and functionally dependent.

Diagnostic tests to detect Alzheimer's early

To determine the existence or not of Alzheimer, a complete neurological study is carried out, which includes MRI test. MRI scan center in east Delhi provides highly detailed images of the brain without emitting radiation harmful to people.

Also, the MRI from MRI scan center and MRI test labs in Delhi can be used to rule out other possible diseases that are causing the symptoms such as spills, tumors or fluid accumulation.

Eating habits to prevent Alzheimer's

Diet is one of the important factors that can prevent the appearance of this disease related to loss of memory and cognitive abilities. In this sense, there are some habits to follow:

  • Saturated or trans fats are bad allies against dementia of this type since negative substances accumulate in the brain.
  • Regular consumption of fruits, vegetables and legumes reduces the risks of cognitive decline.
  • Vitamin E is brain-healthy and can be found in nuts or seeds, mangoes, papayas, avocados, tomatoes, red peppers, spinach, and enriched breads and cereals.
  • Vitamin B is found in products of animal origin and its benefits are noted in memory and in the reduction of muscle atrophy.
  • The consumption of multivitamins such as iron and copper should be avoided unless it is done by prescription.
Answered in Detail: Your Frequently Asked Question on MRI Scans

This has been read, discussed, researched and yet people have been found (time and again) confused! Yes we are talking about MRI or Magnetic Resonance Imaging. Before detailed information about the MRI Scan Centre and the cost involved, we tell you what MRI is in a nutshell. MRI stands for Magnetic Resonance Imaging. It is a noninvasive diagnostic procedure that uses magnetic fields and radio waves to produce a clear and detailed digital image of the human anatomy. By conducting an MRI scan, physicians can detect and identify a number of medical conditions in their early stages and therefore increase the likelihood of recovery. Now it is time to answer some of the frequently asked questions:

1.      Is an MRI safe? Does it Discharge Radiation?

Yes, MRI scan is absolutely safe and it does not exude radiation. The magnet produces radiofrequency waves to scan the body part. Unlike CAT scans; this diagnostic imaging method does not involve any exposure to radiation. In fact, there are no known side effects related to MRI scans. However, because it does involve exposure to a strong magnetic field, patients with certain devices like pacemakers and other implants cannot get an MRI.

2.      What Causes the Noise in the Scanner?

There is nothing dangerous about the scanner making noise. It is basically the electrical current rising within the wires of the gradient magnet which produces a noise. This is because of the reason that the current in the wires are opposing the main magnet field; the stronger the field the louder the gradient noise.

3.      Can the Patient Talk While the MRI Scan is Going On?

You are required to stay still throughout the scan in the MRI Scan testbut you can still communicate with the technician as and when necessary. You may also ask any questions that you have regarding the procedure.

4.      Does it Make People Claustrophobic?

This is something that needs prior attention and information sharing with the MRI Scan center. If you are prone to claustrophobia, make sure to inform your physician about the same well in advance. There are two kinds of MRI machines: open MRI machines and closed MRI machines. The closed unit completely envelopes the patient during the scan, while the open MRI machine is a large ring that patients pass through. For patients who suffer from anxiety in closed spaces, the open MRI unit is ideal.

5.      Why is The Whole Body Put Under the Scan Even if The Scan is Only For The Head?

It is so because the area of the scanner that generates the images is located in the centre of the magnet. This is called the isocentre. Therefore, the scan is possible for your head only when the most of your upper body will be in the scanner. The same is applied when imaging the spine and upper extremities.

6.      How Long Does it take Before Getting the Scan Results?

On completion of the exams, the images are sent to one of the radiologists, (doctors specializing in the evaluation of diagnostic images.) Once read, the radiologist will create a report that will be sent to your referring physician. The entire process usually takes 24-48 hours.

Lastly, the MRI Scan cost is something that everyone is aware of or want an exact detail for. The cost of MRI depends on the body organ which is to be examined. For instance the cost for a MRI hand or Foot (Rt) with Contrast is INR 11500. Similarly MRI whole spine would cost INR 16000.
