A full-body MRI scan is typically used to detect abnormalities such as cancer or as a preventative screening measure, according to the Mayfield Clinic. The MRI works by using a strong magnet to capture precise photos of the body. The information is transferred to a computer, where a detailed image is produced that allows doctors to examine various soft tissues and fluids within the body.
According to the Mayfield Clinic, MRIs allow doctors to examine the human body in slices. Doctors often inject dyes into the arteries, in order to detect blockages and determine whether or not organs are working properly. Full Body MRI Scan in Orange County, California, a clinic which offers full-body MRI scanning services, states that patients with a strong history of cancer and other illnesses in their family are prime candidates for full-body MRI preventative scans. People who currently smoke cigarettes or have smoked in the past, people with high blood pressure, or people experiencing internal pain are also cited as candidates for the service.
A research study from the American Roentgen Ray Society reported in Science Daily argues that while the potential of full-body MRI scanning is promising, more research needs to be done in order to determine its long term effects on the human body.
