A CT scan, or computed tomography scan, combines X-ray images taken from different angles to create cross-sectional images of the body. This allows for a more detailed view than a standard X-ray and is particularly useful for visualizing complex structures. CT scans are commonly used in cancer diagnosis and staging. They can detect tumors in various parts of the body, including the lungs, abdomen, and pelvis. CT scans are often used to guide biopsies, assess the effectiveness of treatment, and monitor for recurrence. The ability to provide detailed images quickly makes CT scans a preferred choice in emergency settings. However, CT scans involve higher radiation exposure compared to standard X-rays, which is a consideration in repeated imaging, especially for young patients or those requiring frequent monitoring.
