Abstrakt

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 the study was to evaluate the application of volumetric reconstructions of the right ventricle for assessment of IVS position regarding its accuracy in identifying right ventricular dysfunction, as well as interobserver agreement in evaluating this sign. IVS bowing was evaluated with multiplanar reformations (MPR) and volumetric reconstruction (VR, volume rendering) by 2 observers. The accuracy of IVS bowing sign was better for VR-based assessment; however, it was not significantly better than the MPR-based evaluation. Interobserver agreement was found to be fair (kappa = 0.381) for the MPR-based grading of IVS position as normal or abnormal, 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 in patients with PE.
