Magnetic resonance imaging
is abbreviated as MRI. MRI is a painless and noninvasive
way to identify prostate cancer stage. Magnetic resonance
imaging can be used to view possible metastasis to the
lymph nodes and bones in advanced prostate cancer. Through
magnetic waves MRI presents a three-dimensional image.
Due to a loud clanging sound of strong electromagnetic
fields being switched on and off, some patients find
the process unpleasant. Patients are confined in a large
chamber for approximately 20 to 45 minutes. Doctors
usually allow patients to wear earplugs or listen to
music through headphones during the procedure. A light
sedative can be administered to patients that are claustrophobic
prior to the procedure.
