摘要目的相位对比心脏MR(PC-CMR)检查有可能快速准确地无创性确定ST段抬高性心肌梗死(STEMI)者左心室功能。方法对90例首次发作的STEMI及15例健康志愿者行左室短轴位电影序列扫描与自由呼吸的回顾性门控PC-CMR。确定阅片者之间及阅片者自身的一致性。计算各项临床指标[年龄、性别、射血分数、脑钠肽前体(NT-proBNP)]与
Abstract Objective To evaluate the noninvasive determination of left ventricular function in patients with ST-segment elevation myocardial infarction (STEMI) by phase contrast MR (PC-CMR). Methods Ninety patients with first episode of STEMI and 15 healthy volunteers underwent retrospective gated PC-CMR with left ventricular short-axis sequence scanning and free breathing. Determine the reader and the reader between the reader’s own consistency. Calculate the clinical indicators [age, gender, ejection fraction, brain natriuretic peptide (NT-proBNP)] and
