Abstract

Bowing of the interventricular septum (IVS) is a sign of severe pulmonary embolism(PE); however, it is affected by high interobserver variability. The aim of thestudy was to evaluate the application of volumetric reconstructions of the rightventricle for assessment of IVS position regarding its accuracy in identifying rightventricular dysfunction, as well as interobserver agreement in evaluating this sign.IVS bowing was evaluated with multiplanar reformations (MPR) and volumetricreconstruction (VR, volume rendering) by 2 observers. The accuracy of IVS bowingsign was better for VR-based assessment; however, it was not significantlybetter than the MPR-based evaluation. Interobserver agreement was found tobe fair (kappa = 0.381) for the MPR-based grading of IVS position as normal orabnormal, while it was significantly better for the VR method (kappa = 0.629,p < 0.001). The VR-based method may improve utilisation of IVS bowing sign inpatients with PE.
