We evaluated the effect of through-plane motion on tricuspid flow measurements performed with MR velocity mapping in nine normal subjects and 15 patients with possible right ventricular (RV) disease. Eight parameters of RV diastolic function were derived from the tricuspid flow measurements, both before and after a correction for through-plane motion. Measurements of E-peak, A-peak, and time-to-peak filling rate changed significantly after correction for through-plane motion (P < .05). Tricuspid flow as a marker of RV diastolic function should be corrected for the effect of through-plane motion to improve functional evaluation of the RV.
我们评估了平面内运动对9名正常受试者和15名可能患有右心室（RV）疾病患者进行磁共振速度映射时三尖瓣血流测量的影响。从三尖瓣血流测量中得出右心室舒张功能的八个参数，分别在对平面内运动进行校正之前和之后。校正平面内运动后，E峰、A峰和峰值充盈率的测量值发生了显著变化（P < .05）。作为右心室舒张功能标志物的三尖瓣血流应校正平面内运动的影响，以改善右心室的功能评估。
