Magnetic resonance imaging, most commonly known as MRI, uses the power of magnetic field to image the tissues of the body. The MRI does not use any radiation. The strength of the magnet is measured in Tesla. Earlier, 1.5 Tesla was used as the standard form for MRI scan. But 3T means three times the Tesla was quantifying the strength of the magnetic field.
The scan is done for various parts of the body for screening purposes. But abdominal aorta is done to screen a possible aneurysm, gallbladder and bile ducts to screen for cancerous growths and stones. There is clarity in the images when 3T MRI scan is done. It benefits the pathologists to infer results.
