Final answer:
CT scans, also known as CAT scans, use X-rays to produce detailed 3D images of the body. CT procedures are also used in other scanning technologies such as PET scans, which rely on radioactive substances.
Step-by-step explanation:
CT scans, also known as CAT scans, use X-rays to produce cross-sectional images of the body. Unlike a standard X-ray that only provides a two-dimensional view, CT scans produce detailed 3D images.
The CT scanner revolves around the patient's body, collecting multiple X-ray measurements from different angles. These measurements are then processed by a computer to create virtual slices of the organ being scanned.
CT procedures are also used in other scanning technologies such as PET (Positron Emission Tomography) scans, which rely on radioactive substances and are used in chemotherapy.
CT scans provide valuable information about the size, shape, and location of tumors or other abnormalities that help guide the treatment process.
