What technology is used to capture images in a PET scan?

• A. X-ray machines
• B. Ultrasound devices
• C. Detectors identifying gamma rays
• D. Magnetic resonance imaging systems

Answer: (C)

In a PET scan, the primary technology used for capturing images is the detection of gamma rays. When a radiopharmaceutical is administered to the patient, it emits positrons that collide with electrons in the body, resulting in the production of gamma rays. These gamma rays are then detected by specialized detectors within the PET scanner, which convert the information into images that represent metabolic activity in tissues. This process allows for detailed insight into various physiological processes, making PET scanning a valuable tool for diagnosing and monitoring conditions such as cancer, heart disease, and neurological disorders. By accurately detecting the gamma rays emitted from the radiotracer, PET scans provide crucial information that is often not accessible through other imaging modalities.
