The radiotracer eventually collects in the area of the body being examined, where it gives off energy in the form of gamma rays. This energy is detected by a device called a gamma camera. These devices work together with a computer to measure the amount of radiotracer absorbed by your body and to produce special pictures offering details on both the structure and function of organs and other internal body parts.
Nuclear scintigraphy is used to diagnose:
• portosystemic shunts
• kidney function
• distribution of cancer in the body
• thyroid disease
