Question

Which of the following indicates the advantage of the CAT on a radiograph?

• A. It has high resolution
• B. It avoids superimposition of image
• C. It is cheaper than a radiograph
• D. Both A and B

Answer 1

The correct option is D Both A and B

CAT (Computer Axial Tomography) has certain advantages over radiography as it provides better resolution through all the three dimensions and since the x ray tub rotates 360${}^0$ it takes multiple images of the concerned anatomical structure. Then combines them together to form a single image.This provides only the required part of the image without any overlapping.

So, the correct answer is 'Both A and B'
