摘要目的本研究的目的是应用非对比剂增强T1mapping和细胞外容积分数(ECV)评估慢性血栓栓塞性肺动脉高压(CTEPH)的室间隔和右心室插入点(RVIP)纤维化的测定,并分析功能参数的相互关系。方法 24例诊断为CTEPH的病人和24例对照组进行了1.5 T MR成像。测定基底水平短轴切面的室间隔心肌、上下RVIP和侧壁的T1值。结果 室
Abstract Objectives The purpose of this study was to evaluate the measurement of ventricular septum and right ventricular insertion (RVIP) fibrosis in patients with chronic thromboembolic pulmonary hypertension (CTEPH) using contrast-enhanced T1mapping and extracellular volume fraction (ECV) The relationship between parameters. Methods Twenty-four patients with CTEPH and 24 controls were examined by 1.5 T MR imaging. Measurements of T1 values at the basal horizontal short axis of the interventricular septum, RVIP and sidewalls. Results room
