目的 :心肌灌注 -代谢不匹配主要由 PET检测。近来 ,将1 8F-氟代脱氧葡萄糖 (1 8F- FDG)与 99Tcm标记的灌注示踪剂相结合 ,用双同位素同时采集 (DISA) SPECT来检测灌注 -代谢不匹配心肌 ,便可提供与 PET等同的临床信息。此研究用99Tcm- tetrofosmin和 1 8F- FDG DISA SPECT显像
Purpose: Myocardial perfusion - metabolic mismatch is mainly detected by PET. Recently, the combination of 18F-fluorodeoxyglucose (18F-FDG) with a 99Tcm-labeled perfusion tracer to detect perfused-metabolically uncoordinated myocardium with simultaneous dual isotope collection (DISA) SPECT provides an alternative to PET Equivalent clinical information. This study used 99Tcm-tetrofosmin and 18F-FDG DISA SPECT imaging
