摘要：

We evaluated the effect of through-plane motion on tricuspid now 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 now 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 now as a marker of RV diastolic function should be corrected for the effect of through-plane motion to improve functional evaluation of the RV.
