MRIs

Diagnosing mesothelioma can sometimes be difficult and it takes sophisticated equipment to get the job done.  Some doctors will suggest that an MRI be performed to ascertain a solid diagnosis. 

An MRI (Magnetic Resonance Imaging) is an easy and painless procedure that uses a magnetic field and radio waves to create cross-sectional images of your head and body.  These images are extremely clear and distinct and give doctors a good idea of what may be causing problems for their patients.

This non-invasive procedure is especially good for diagnosing central nervous system disorders, but for potential meso patients, it helps doctors detect tumors in or around the lungs. 

Preparing for an MRI

There is little to do to prepare for this type of imaging.  No fasting or special diet is required though contrast dyes are sometimes used.  These are unlikely to cause any reactions.

If you’re wearing anything that’s metal, you’ll be asked to remove it.  Anyone with metal objects inside their body, like a metallic joint prosthesis or an artificial heart valve, should warn the technician as to the presence of these objects.  MRIs are not performed on those with pacemakers or implanted cardioverter defibrillators.

Patients undergoing an MRI lie on a moving table that slides through the MRI machine.  The MRI machine creates a strong magnetic field around you, and radio waves are directed at your body.  You may hear lots of noises during the procedure and often, you’ll be offered ear plugs or music to block out the sometimes annoying and repetitive sounds.

Most MRI procedures last from 30 to 90 minutes.  Some people begin to feel claustrophobic during the MRI.  If you have a problem with closed-in spaces, tell your doctor before the procedure.  You may have the option of having the procedure performed on an “open” MRI, available at many facilities.  If an open machine is not available, your doctor may offer a sedative.

Results

The results of your MRI will not be available to you immediately but you may be asked to remain in the room for a few minutes while technicians check to be sure the procedure produced readable images.  A radiologist will review your test and forward results to your doctor a few days later.
