The procedure is also known as computed axial tomography (CAT scan). Computed tomography, commonly known as a CT scan, combines multiple X-ray images with the aid of a computer to produce cross-sectional views of the mint-body.comc CT is a heart-imaging test that.
A CT Scan (or CAT Scan) is best suited for viewing bone injuries, diagnosing lung and chest problems, and detecting cancers. An MRI is suited for examining soft tissue in ligament and tendon injuries, spinal cord injuries, brain tumors, etc.
CT scans are widely used in emergency rooms because the.Download
