What is MRI?

MRI is a medical technique that uses MRI principles to image large organs and large blood vessels in patients. It plays a better role in early screening and diagnosis, especially in screening tumors and cardiovascular and cerebrovascular diseases. Because MRI is operated through magnetic fields, it cannot be examined with metals on the body; patients with severe illness or claustrophobia are not suitable for this examination, because the whole process takes 10-20 minutes, and patients are difficult to cooperate.
