Computed Tomography (CT )

Computed tomography (CT) uses X-rays and computerized image processing technology to create highly-detailed images of organs and tissues inside the body. The exam procedures are often called CT scans or CAT scans, with CAT standing for computerized axial tomography. The images from CT scans are usually divided into sections, called “image slices,” that allow doctors to examine organs and tissues at different depths for signs of disease, abnormality, or injury.

Doctors order CT scans for a variety of reasons, such as testing for signs of disease in the heart and blood vessels, screening for cancer, diagnosing cancer or tumors, diagnosing disorders of the internal organs, planning cancer treatment, or diagnosing neurological diseases and conditions. CT scans are frequently used for studies of the head, chest, abdomen, or spine.
