MRI

MRI stands for Magnetic Resonance Imaging. It is a technique used in medical science that provides images of the physical processes of the body. The anatomy of the body is also pictured in this technique. Well, it is a technique used under radiology, wherein radio waves are used to generate pictures of the body. Well, it is interesting to note that MRI does not use the X-Ray technique. People go for MRI in order to diagnose a disease in an individual.

CT Scan

CT Scan stands for Computerized Tomography Scan. It is a technique used in medical science, wherein the images are taken with the help of X-Rays. The images are taken from various angles, and several images are provided, like the cross-sectional pictures of bones and other body parts. Well, it is interesting to note that the pictures provided by CT Scan are much more informative and detailed as compared to MRI. CT Scans are able to detect disorders related to joints and bones. That is why cross-sectional images are taken in CT Scans. Now, having discussed the basic definition of MRI and CT Scan, let us take a look at some points of contrast between them.

So, these are some points of contrast related to MRI and CT Scan. Now, you must be wondering as to which method of diagnosing is better. Well, both MRI and CT Scan are safe options. But they have related risks. People prefer MRI scans as the images produced are clear, detailed, and informative. The risks related to MRI and CT Scan depend upon the images.
