Diagnostic value of multidetector row CT in rectal cancer staging: a comparison of multiplanar and axial images with histopathology

Abstract

Aim: Although magnetic resonance (MR) imaging is widely used for rectal cancer staging, many centers in the UK perform computed tomography (CT) for staging rectal cancer at present. Furthermore, in a small proportion of cases, contraindications to MR imaging may lead to staging using CT. The purpose of this study was to evaluate the accuracy of current generation multidetector row CT (MDCT) in local staging of rectal cancer. In particular, the accuracy of multiplanar (MPR) versus axial images in the staging of rectal cancer was assessed.
