What is Radioisotopes used in Myocardial perfusion imaging: Thallium 201 18 FDG PET Tc-99m Sestamibi Tc-99m Pyrophosphate Tetrafosmin N-13 Ammonium and explain in detail?
- Thallium-201, Sestamibi, Tetrofosmin scan are used for Myocardial Perfusion Imaging. - Pyrophosphate scan for Myocardial Infarction. - 18 FDG PET is used to detect Myocardial Viability - N-13ammoniaPETmyocardial perfusion imaging(MPI) yields larger stressperfusiondefects than dipyridamole stress and might reflect the truemyocardialischemic burden.
