CZT心脏专用SPECT心肌血流定量技术临床应用中国专家共识

Chinese expert consensus on the clinical application of CZT cardiac-dedicated SPECT myocardial blood flow quantification technique

PET/CT心肌血流量(MBF)定量技术被认为是目前无创评估MBF和心肌血流储备(MFR)的“金标准”,但由于受正电子心肌灌注显像药物获取困难等多种因素的限制,该技术在我国临床实践工作中开展的并不理想。采用全新半导体碲锌镉(CZT)探测器的心脏专用SPECT定量技术近些年在国内逐步开展,可实现定量评估MBF和MFR。本专家共识介绍了CZT心脏专用SPECT MBF定量技术的相关药物准备、具体步骤及其在临床应用中所提供的诊断与预后价值,希望有助于进一步规范和推广该技术在国内的应用。

PET/CT myocardial blood flow(MBF)quantification technique is currently considered to be the'gold standard'for non-invasive assessment of MBF and myocardial flow reserve(MFR).Nevertheless,due to various limitations such as difficulties in obtaining positron-emitting myocardial perfusion imaging agents,this technique is not well developed in clinical practice in China.The cardiac-dedicated SPECT MBF quantification technique equipped with a new semiconductor cadmium zinc telluride(CZT)detector has been used in clinical practice in China recently,which can provide quantitative assessment of MBF and MFR.This expert consensus introduces the related medication preparation,acquisition protocols,and the diagnostic and prognostic value of CZTdedicated SPECT MBF quantitative technology in clinical applications,which in order to further regulate and promote its application in China.
