Sestamibi Scans

Like the thallium scan, the sestamibi or tetrofosmin scan shows how well supplied with blood and your heart is. Sestamibi (Cardiolite) and tetrofosmin (Myoview) refer to the type of radioactive isotope (Tc-99m sestamibi or Tc-99m-tetrofosmin) used in this test to make the flow of blood visible. Thallium, sestamibi and tetrofosmin stress tests are more accurate and informative than a standard exercise stress test.
