What is a radioactive MRI?

Unlike X-ray, CT, and PET scans, MRIs do not use radiation and is considered a non-invasive procedure. Instead, MRIs use a strong magnetic field and radio waves to take pictures of your brain. The MRI scanner is a metal cylinder surrounded by a strong magnetic field.

What is a limited MRI?

The quickest exam we take of the brain is called an MRI Limited Brain. These pictures are quick sequences that are set up to only take about 5 minutes and, as the name suggests, it is a very limited study.

What is a MRI simple definition?

: a noninvasive diagnostic technique that produces computerized images of internal body tissues and is based on nuclear magnetic resonance of atoms within the body induced by the application of radio waves. — called also MRI.

What is a sedated MRI?

Sedation is medication given to patients to help them remain still during an MRI scan. Lying still is critical to insuring that the MRI pictures taken will be accurate and clear.

Which is the best glossary of MRI terms?

Glossary of MRI Terms Glossary of MRI Terms A Absorption mode. Component of the MR signal that yields a symmetric, positive-valued line shape. Acceleration factor. The multiplicative term by which faster imaging pulse sequences such as multiple echo imagingreduce total imaging time compared to conventional imaging sequences such as spin echo

What does a MRI do for a child?

What is a Children’s (Pediatric) MRI? Magnetic resonance imaging (MRI) is a noninvasive test used by physicians to diagnose and treat medical conditions. Detailed MRIs help to evaluate internal body organs and determine the presence of disease. A large, cylindrical-shaped, tubular machine creates a strong magnetic field around the patient.

What kind of images can you get from a MRI?

In some cases, it can provide clear images of body parts that can’t be seen as well with an X-ray, CAT scan, or ultrasound. MRI is particularly valuable for diagnosing problems with the eyes, ears, heart, and circulatory system.

How long does a child have to lie on a MRI table?

Your child may have to lie still on the MRI table for 20-90 minutes during the procedure, but there are brief breaks between each scan. Unless sedation is used or you’re told otherwise, your child can immediately return to normal routines and diet. If your child feels cold lying on the MRI table, a blanket can be provided.
