CT Scan v's MRI

I think MRI is better than CT Scan.
About MRI:
Magnetic resonance imaging (MRI), formerly referred to as magnetic resonance tomography (MRT) or, in chemistry, nuclear magnetic resonance (NMR), is a non-invasive method used to render images of the inside of an object. It is primarily used in medical imaging to demonstrate pathological or other physiological alterations of living tissues.
