MR VELOCITY MAPPING OF TRICUSPID FLOW - CORRECTION FOR THROUGH-PLANE MOTION

We evaluated the effect of through-plane motion on tricuspid now measu rements performed with MR velocity mapping in nine normal subjects and 15 patients with possible right ventricular [RV] disease, Eight param eters of RV diastolic function were derived from the tricuspid now mea surements, both before and after a correction for through-plane motion , Measurements of E-peak, A-peak, and time-to-peak filling rate change d significantly after correction for through-plane motion (P < .05), T ricuspid now as a marker of RV diastolic function should be corrected for the effect of through-plane motion to improve functional evaluatio n of the RV.
