A computed tomography (CT) scan, also known as a CAT scan, uses X-rays to make highly detailed pictures of the inside of the human body. A CT scan involves the patient laying down on mechanical table that is inserted into the CT machine. A scanner takes X-rays images and spins around the patient as the table moves into the machine, which is compiled into a cross sectional image.
A CT scan can be used to study all parts of the body including organs, blood vessels, bones, chest, abdomen, extremities, and the spinal cord.A CT may be required in cases where the patient has a condition that prevents the use of an MRI such as a metal implant, shrapnel, pacemakers, etc.
