An MRI scanner is operated by a radiologic technologist and is used for the imaging of a certain part of the body. You can speak to your technologist during the procedure via a microphone in the machine. If you have a history of claustrophobia, you may be given a sedative drug to relieve anxiety during the procedure.
Once you are in the MRI machine, a strong magnetic field is created around you or the part of the body being scanned. The procedure is completely painless. The protons in your body, or the specific area of your body, will line up in a single direction. Short bursts of radio waves will be directed at your body, or a specific area of your body, that will cause these protons to emit radio signals. These signals are then combined like pixels on a computer screen to create detailed imaging of tissue, bone, and organs inside your body.
In some cases, a contrasting agent may be injected through your veins to enhance visual details in your scan. Gadolinium is the most frequently used contrast agent for MRI scans. Side effects of gadolinium are mild but may produce a chilling effect at the injection site or a “pins and needles” feeling. Sesame offers MRI procedures with and without contrast.
The scan can last anywhere from 15 to 90 minutes, depending on the area of the body being examined, and how many images must be collected. The internal part of the magnet produces noise that can be blocked out with earplugs or music played during the procedure. Connect with doctors on Sesame to determine the MRI procedure that works best for you.
MRI services are completely painless and non-invasive. If you haven't been sedated, you can resume your usual activities immediately after the MRI.
