CT Scan
A CT (Computed Tomography) scan is a medical imaging procedure that combines X-rays and computer technology to generate detailed cross-sectional images of the body’s internal structures. It’s an invaluable diagnostic tool for a wide range of medical conditions, offering a swift and comprehensive view of organs, bones, blood vessels, and soft tissues. CT scans are particularly useful for identifying injuries, tumors, and evaluating the extent of diseases. Unlike traditional X-rays, CT scans provide three-dimensional images, aiding healthcare professionals in precise diagnosis and treatment planning. They are non-invasive and typically take only a few minutes, making them a critical component of modern medical diagnostics.
During a CT scan, a rotating X-ray machine captures multiple images from different angles. A computer then processes these images to create detailed cross-sectional images.
CT scans expose you to a small amount of radiation, but the benefits of accurate diagnosis usually outweigh the risks. The radiation dose is kept as low as reasonably achievable, and your doctor will consider the necessity of the scan.
The need to fast before a CT scan depends on the specific scan and your doctor’s instructions. In some cases, you may be asked to avoid eating or drinking for a certain period before the scan.
The duration of a CT scan can vary, but most scans take only a few minutes to complete. More complex scans may take longer.
