CT scans are crucial for diagnosing conditions like bone fractures, internal bleeding, tumors, infections, and guiding medical procedures. They offer detailed views of organs, soft tissues, bones, and blood vessels.
A CT scanner rotates an X-ray source around the patient, taking numerous images from various angles. A powerful computer then processes these images to generate detailed cross-sectional 'slices' of the body.
CT scans expose patients to a small, controlled amount of ionizing radiation. While generally safe, medical professionals carefully assess the benefits against potential risks, especially for sensitive groups.
The actual scanning process is usually quick, often ranging from 5 to 30 minutes, depending on the area being examined and whether a contrast agent is administered.
