CT Scan - Computed Tomography (General Practice)

Computed Tomography, also known as CT or CAT scan, is a medical imaging technique that uses X-rays and computer algorithms to create cross-sectional images of the body. These images are far more detailed than conventional X-rays, allowing physicians to detect abnormalities in organs, bones, and tissues with greater accuracy. CT scans are commonly used to diagnose a wide range of medical conditions, including cancer, cardiovascular disease, and musculoskeletal disorders.

During a CT scan, the patient lies down on a table that moves slowly through a large, doughnut-shaped machine called a CT scanner. As the patient moves through the scanner, X-ray beams are directed at the body from various angles. The X-rays are detected by sensors on the opposite side of the scanner, which send the information to a computer. The computer then uses this information to construct a series of detailed, cross-sectional images of the body.

Because CT scans involve exposure to ionizing radiation, they should only be used when the benefits of the test outweigh the risks. Patients who are pregnant or may be pregnant should avoid CT scans if possible, as radiation can harm the developing fetus. Additionally, patients with kidney problems may not be able to receive contrast dye, which is often used to enhance the visibility of certain tissues during CT scans. It is important for patients to discuss the risks and benefits of CT scans with their healthcare provider before undergoing the procedure.
