CT Scan
CT Scan
A CT scan, or computed tomography scan, is a noninvasive medical imaging procedure that uses X-rays and a computer to create detailed cross-sectional images of the inside of the body. CT scans can be used for a variety of purposes, including: Diagnosing disease, Planning treatment, Evaluating how well treatment is working, Investigating internal bleeding, Checking for internal injuries or damage, Performing a tissue or fluid biopsy, CT scans are more detailed than standard X-rays because the X-ray beam moves in a circle around the body, allowing for many different views of the same organ or structure. During a CT scan, a dye may be injected into a vein or swallowed to help the organs and tissues show up more clearly. CT scans expose patients to a type of energy called ionizing radiation, but the low doses used are not expected to cause long-term harm. However, repeated scans may slightly increase the lifetime risk of cancer.
