Magnetic Resonance In Children

Brain resonance is primarily used when a structural brain injury is suspected, that is, a problem that we can "photograph."

As in all the complementary tests, the information it offers is of no value if the context of symptoms and signs of the patient that the neurosurgeon will have obtained during the medical visit and with which he will develop a diagnostic hypothesis is not taken into account.

It is essential in the study of pathologies that occur with alterations in brain structure such as childhood cerebral palsy, malformations, or the consequences of trauma or infection, among others.

It is also used in the study of some types of epilepsy, to ensure that there is no underlying cause. And very rarely before a headache.

For the study of vascular diseases, tumours, neurodegenerative processes, and prior to brain surgery, the MRI images are combined with other special resonance techniques:

  • Spectroscopy:

Provides information on brain metabolism

  • Diffusion: study the microscopic molecular movement
  • Perfusion: allows to see cerebral blood flow
  • Angiography:

Visualize, after contrast injection, arteries, and veins

  • Tractography:

To see the structure of brain fibers

  • Functional MRI:

The image is obtained while the patient performs a task and their brain activity is studied

How is a resonance made?

Unlike other imaging techniques, such as simple radiology or CT, magnetic resonance imaging does not use radiation (X-rays), but rather very strong magnets and radio waves that have no side effects. This makes resonance, along with ultrasound, the safest and safest procedure to obtain body images.

The waves pass through the tissue to be studied, finding different resistance depending on the amount of water it contains. Thus, the device produces a very reliable and accurate map of the studied area much sharper than that obtained by other techniques.

The strong magnetic fields that are created during an MRI force to remove all metal objects from the room. Even smaller objects cause interference by vibrating under the force of the magnet, resulting in blurry images without utility, large objects can fly away, causing accidents. Before having an MRI, one should know the MRI test cost in Noida.

That is why the patient should take off his clothes and put on a hospital gown before laying him on the narrow stretcher that slides inside the resonance tube. To better visualize the images, contrast is sometimes given to the patient through an intravenous line. The most widely used is gadolinium, which is very safe and rarely causes side effects - nausea and local pain - and very rarely allergic reactions. It is contraindicated in patients with severe kidney problems.

The time required to obtain the images is very long, about 30 minutes minimum - depending on the surface to be studied, and the patient must be absolutely still so that they do not get blurred. In addition, the intense noise of the device prevents spontaneous sleep. Children under 6 years of age and children with difficulties to collaborate need to be sedated so that the MRI obtains clear images. Sedation will be done by MRI test labs in Delhi who will be present throughout the examination.

Examination Of The Gastrointestinal Tract By MRI And CT

When examining the gastrointestinal tract and suspecting a serious illness, a computer (CT) or magnetic resonance imaging (MRI) scan is performed. Only these two types of examinations can give a full picture of violations in the digestive tract. With more common diseases, ulcers, bowel obstruction, polyps, CT is usually prescribed, which within 15 minutes will reveal all the disorders, including internal bleeding. MRI is prescribed by an MRI scan centres in Noida in more complex cases, with suspected neoplasms in the gastrointestinal tract or when other examination options do not give an exact answer in determining the disease.

Pay attention to your intestines with the following symptoms:

  • Black feces or blood feces (see a doctor immediately)
  • Often recurring pain in the abdomen or anus
  • Prolonged feeling of nausea
  • Prolonged constipation
  • Bloating
  • Frequent diarrhea

MRI is prescribed to the patient to obtain the final picture of the disease, as well as:

  • With suspected tumors
  • If the patient is pregnant

This is explained by the fact that in MRI, unlike CT, the patient is not exposed to aggressive radiation during the procedure. Therefore, CT is strictly contraindicated for pregnant women, and MRI is allowed from the third month. CT can also not be done more than once a year. CT is prescribed for suspected internal bleeding, and when there is a suspicion of a violation of the complete integrity of the intestines and stomach. Also, when there is a suspicion of acute bowel obstruction. With CT, the patient is exposed to radiation; with this, there are limitations in its use.

With CT, doctors can accurately determine the state of the gastrointestinal tissue and the violation of their integrity, determines wall defects, perforation of the stomach and intestines, and the state of sphincters.

MRI gives a picture of changes in cell metabolism and reveals significant pathologies, including malignant and benign tumors, cholelithiasis, and inflammatory processes in the pancreas.

It is not difficult to prepare these procedures:

  • Forget about vegetables, fruits, grain bread and other products containing coarse fiber per day
  • 8 hours before the examination, stop any meal
  • An hour before the procedure, take 5-6 tablets of activated carbon, if there are no contraindications.

WHAT TO CHOOSE: CT OR MRI?

When choosing between CT and MRI, it is necessary to take into account the features of each type of examination and recommendations of MRI scan centers in east Delhi. When making a decision, the following factors should be considered:

The clinical picture. If you suspect diseases such as an ulcer, polyp, other disorders in the structure of the intestinal wall or obstruction, they often turn to computed tomography. This examination allows you to detect internal bleeding, which helps to save the patient's life. Due to the fact that the study takes no more than 10-15 minutes, the diagnosis of an injury to the gastrointestinal tract and the appointment of the necessary treatment is fast enough.

Suspicion of oncology. MRI of the gastrointestinal tract allows you to get an accurate diagnosis regarding cancer. Finding a tumor, especially in the pancreas, is quite difficult, especially in acute inflammation. This method provides an accurate diagnosis of such pathology and makes it possible to prescribe effective therapy.

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.
Cardiomyopathy: Tomography, MRI of the Heart, What will Show?

In examining patients with cardiomyopathy, various imaging techniques are used to determine the form of the disease, the severity of heart damage. This is magnetic resonance imaging or conventional computed tomography, the study of coronary arteries with contrast, as well as a specific stress test using thallium, a labeled isotope. A sleep study in the lab with polysomnography is also shown. Why is all this necessary?

Thallium Stress Tests: A Heart Exam

Many patients with dilated or restrictive cardiomyopathy can undergo a cardiac stress test with thallium to assess how well the heart is supplied with blood, how effective the ventricles or atria are. This information is used to decide the best way to treat patients.

Magnetic resonance imaging (MRI) for cardiomyopathy

MRI uses strong magnetic fields and radio waves instead of radiation to create three-dimensional images and two-dimensional cross-sections of the heart. Images created with magnetic resonance imaging, similar to x-rays, but show more detailed information about the soft tissues of the body.

Magnetic resonance imaging is performed in a large tube by MRI Scan Centres in Noida that is wide enough to accommodate a patient lying on a couch. Radio waves and strong magnetic fields are generated inside the shell of the tube and directed towards the body during magnetic resonance imaging. The body reacts by emitting weak energy signals that are detected by a scanner. A computer converts these signals into three-dimensional images of the heart that can be moved to obtain any two-dimensional cross-section.

Magnetic resonance imaging involves the removal from the body of all accessories and clothing containing metal, including jewelry, metal fasteners, prostheses, wigs and hearing aids. Metallic objects can interfere with the magnetic field, affecting image quality. Magnetic resonance imaging is painless; it usually lasts from 30 to 60 minutes.

The procedure involves lying on a table that slides into the tube. The motion may blur images, so it is important to lie still. The space inside the tube is rather narrow, and some patients may feel uncomfortable. Patients are often offered headphones or earplugs that help block out loud squeaking and percussion sounds generated by an MRI machine.

MRI examination of the coronary arteries Magnetic resonance angiography (MRA) of the coronary arteries is one of the new applications of MRI. For this test, a contrast agent is injected into the vein on the arm. Contrast medication facilitates visualization of the heart and reveals the coronary arteries. One of the advantages of an MRA is that contrast agents tend to cause fewer allergic reactions than those used during computed tomography.

There are no known risks from magnetic fields, and radio waves generated when the coronary arteries are visualized. However, people who have pacemakers, cardioverter defibrillators, or other metal-containing objects inside the body cannot be examined with MRI. Also, the effect of magnetic fields on the fetus is not well understood, so an MRI scan is not recommended for pregnant women.

Computed tomography in the diagnosis

If there is evidence, computed tomography is also performed, but it may not provide the full amount of information, especially if it is performed without contrasting. However, for patients with implanted electronic devices, tomography is the only choice.
