CT Angiography Scan (CTA)

A CT scan, or computed tomography scan, is a medical imaging technique that uses X-rays and computer processing to create detailed cross-sectional images of the body. During a CT scan, the patient lies on a table that moves through a doughnut-shaped machine called a CT scanner. The scanner rotates around the body, emitting X-ray beams from multiple angles. These X-rays are detected by sensors in the machine and converted into digital images by a computer.

CT scans are particularly useful for visualizing bones, internal organs, soft tissues, and blood vessels. They can help diagnose a wide range of conditions, including bone fractures, tumors, infections, internal bleeding, and organ damage. CT scans are often used in emergency situations due to their speed and ability to provide detailed images of trauma injuries. Depending on the area being scanned, contrast dye may be injected into a vein to enhance the visibility of certain structures or abnormalities.
