Computed Tomography (CT SCAN)
Introduction

CT scanning is a diagnostic imaging procedure that uses x-rays to build cross-sectional images ("slices") of the body and organs.

It uses a combination of X-rays and a computer to create pictures of the organs, bones, and other tissues. CT Scan reproduces higher resolution images compared to a regular X-ray.
