PedCAT for 3D-Imaging in Standing Position Allows for More Accurate Bone Position (Angle) Measurement than Radiographs or CT

Publication date: Available online 9 May 2014 Source: Foot and Ankle Surgery Author(s): Martinus Richter , Bernd Seidl , Stefan Zech , Sarah Hahn Background PedCAT (Curvebeam, Warrington, USA) is a new technology that allows 3D imaging with full weight bearing which is be not influenced by projection and/or foot orientation (as radiographs). The aim of this study was to compare time spent of the image acquisition, and comparison of specific bone position (angle) measurements between three imaging methods (radiographs, CT, pedCAT), and to analyse and compare measurement differences and inter- and intraobserver reliability. Methods In a prospective consecutive controlled study, 30 patients in which standard digital radiographs with full weight bearing in standing position (feet bilateral dorsoplantar and lateral views and Saltzman hindfoot view), CT without weight bearing, and pedCAT scan with full weight bearing in standing position were included, starting July 1, 2013.
