What is the difference between CT and MRI?

Advantages and disadvantages of each

CT single-density imaging, image interpretation is easy, soft tissue resolution is relatively poor, bones, calcifications are well displayed, there is radiation, and contrast agents have the risk of iodine allergy. Direct cross-sectional imaging, high-end multi-slice CT reconstruction in other directions can often use contrast agents, and the examination time is short

MRI multi-parameter imaging, image interpretation is difficult, soft tissue has high resolution, poor display of bone cortex and calcification, no radiation, contrast agent is safe, imaging in any direction, vascular imaging, water imaging generally does not require the use of contrast agent, the examination time is long due to different imaging principles.
