近来研究表明心脏MR和MDCT通过计算返流口解剖面积的方法可对主动脉返流(AR)进行定量评价,但此种测量并未与AR的定量评价如邻近等值面积区(PISA)经胸壁超声心动
Recent studies have shown that cardiac MR and MDCT can be used to quantitatively evaluate aortic regurgitation (AR) by calculating the anatomical area of the regurgitation port. However, this measurement is not related to the quantitative evaluation of AR such as the PISA Chest wall echocardiography
