Standardized three dimensional computerised tomography scanner reconstructions increase the accuracy of acetabular fracture classification

Purpose Evaluate the role of four standardized 3D reconstruction views in the accurate diagnosis of acetabular fractures. Materials and methods Thirty-five acetabular fracture cases were selected from a tertiary centre database. Fourteen reviewers with different experience level evaluated this set o...

Description
Summary:Purpose Evaluate the role of four standardized 3D reconstruction views in the accurate diagnosis of acetabular fractures. Materials and methods Thirty-five acetabular fracture cases were selected from a tertiary centre database. Fourteen reviewers with different experience level evaluated this set of images which were provided in axial 2D views and multiplanar reconstruction (MPR) without 3D views in the first two readings then the standardized 3D views were added for the subsequent two readings. The primary outcome was the accuracy of diagnosis while inter-observer reliability and reading time as well as time needed for accurate diagnosis were evaluated. Results Accuracy of classification was 56.7% using the 2D and 73% using the described 3D ( p
