Step-by-step explanation:
A liver and spleen scan, also known as a liver-spleen scintigraphy, is a nuclear imaging test that can detect abnormalities or diseases in the liver and spleen. It uses a radioactive tracer substance that is injected into a vein and absorbed by the liver and spleen. A special camera then takes pictures of the tracer as it interacts with these organs. This scan can help diagnose conditions such as liver tumors, liver abscesses, liver cirrhosis, spleen disorders, and blood disorders affecting the liver and spleen.
