目的评估心脏MRI下列3种半定量方法(SQt)[三尖瓣环平面收缩期位移(TAPSE)、右心室缩短分数(RVFS)及右心室面积变化分数(RVFAC)]对后天性心脏病病人右心室(RV)收缩功能的诊断准确性与变异性。方法连续的60例病人纳入研究,以短轴电影序列测量的右心室射血分数
Objectives To evaluate the effect of cardiac MRI on SQt [TAPSE], right ventricular fractional RVF (RVFS) and right ventricular area fraction (RVFAC) in patients with acquired heart disease Diagnostic accuracy and variability of ventricular (RV) systolic function. Methods Sixty consecutive patients were included in the study, with right ventricular ejection fraction
