1.5T and 3.0T MRI prostate exams are two types of MRI exams of the prostate, each with its own advantages. 1.5T MRI: The field strength is low compared to 3.0T MRI, the body absorbs less heat, motion artifacts and chemical shifts have less impact, and restrictions are more lenient for patients with metal implants in the body. 3.0T MRI: the field strength of static magnetic field, better signal-to-noise ratio, higher image resolution, shorter scanning time in comparison, but motion artifacts and chemical shifts are more obvious, and the requirements for patients with metal implants in the body are more stringent. Prostate magnetic resonance examination, should be based on personal condition needs, follow the doctor’s instructions to choose the appropriate magnetic resonance examination.
