Radioisotopes used in Myocardial perfusion imaging: Thallium 201 18 FDG PET Tc-99m Sestamibi Tc-99m Pyrophosphate Tetrafosmin N-13 Ammonium: (A) 1,3,4,5, (B) 1,2,3,4,5,6, (C) 1,3,5,6, (D) 1,3,4,5,6
Answer is B. - 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.
