What is a CT scan and how does it work?
A CT scan, also known as a computed tomography scan, is a medical imaging test used to produce detailed cross-sectional images of the body. It works by using a combination of X-rays and computer technology to create images of the internal structures of the body. During a CT scan, the patient lies on a table that slides into a large, doughnut-shaped machine. The machine rotates around the patient, taking X-ray images from different angles. These images are then reconstructed by a computer to produce detailed cross-sectional images of the body.
The images produced by a CT scan can be used to diagnose a wide range of medical conditions, including injuries, cancers, and vascular diseases. The test is often used to guide biopsies and other minimally invasive procedures, and it can also be used to monitor the effectiveness of treatments.
