What is magnetic resonance CT?

Magnetic resonance CT, also known as "magnetic resonance imaging" or MRI (magnetic resonance imaging), is usually referred to as "magnetic resonance" for short. Compared with XCT, MRI does not use ionizing radiation for imaging, but it is superior to XCT in medical diagnosis: it will not kill human cells; Not only the density map can be obtained, but also three maps of density, T 1 and T2 can be obtained. Can better distinguish soft tissues; Can penetrate bone; The resolution is better than 0.3 mm, of course, MRI also has limitations: patients with metal or pacemakers in their bodies are not suitable for this kind of examination, and people with claustrophobia can hardly bear it.
