PET and CT Scan are two imaging techniques that are commonly used in the medical field to help diagnose and monitor a variety of health conditions.
PET, or positron emission tomography, uses a radioactive substance known as a tracer to create images of the body's metabolic activity. During the procedure, the patient is injected with the tracer, which is absorbed by the body's tissues and organs. The tracer emits tiny particles known as positrons, which are detected by a special camera that produces detailed, three-dimensional images of the area being scanned. PET scans are often used to detect cancer, heart disease, and brain disorders.
CT, or computed tomography, uses X-rays and computer technology to create detailed images of the body's internal structures. During the procedure, the patient lies on a table that slides into a doughnut-shaped machine. X-rays are then emitted from various angles and detected by the machine, which produces a series of images that are combined to create a detailed, cross-sectional view of the area being scanned.
CT scans are often used to diagnose injuries, infections, and other medical conditions. Both PET and CT scans are considered safe and non-invasive procedures, although they do involve exposure to small amounts of radiation. Your healthcare provider will work with you to determine which type of scan is best for your individual needs and will provide you with detailed instructions on how to prepare for the procedure. If you have any concerns or questions about PET or CT scans, be sure to discuss them with your healthcare provider.
