RBC (Nuclear) Scan
Definition An RBC nuclear scan is a group of tests using small amounts of radioactive material to mark (tag) red blood cells (RBCs). The body is then scanned to detect the location and flow of the tagged RBCs (see also nuclear ventriculography).
Why is the Test Performed?
Most often it is used to evaluate blood-flow patterns (nuclear ventriculography), or to locate the site of gastrointestinal bleeding. It may also be used to look for hemangioma within the liver. Occasionally, it is used to evaluate the rate of blood loss in some anemias, or to evaluate blood vessel obstructions.
