Introduction

Magnetic resonance imaging (MRI) is recognised as providing the ‘gold standard’ assessment of fistula-in-ano anatomy, knowledge which is fundamental to a successful clinical outcome [1]. However, interpretation of two-dimensional (2D) monotone magnetic resonance images can prove difficult for the operating surgeon, who is more used to visualising anatomical structures in three dimensions. We describe an imaging technique enabling three-dimensional (3D) reconstruction of complex fistula-in-ano disease.

Technique

Imaging is performed following a standard pelvic imaging protocol on a 1.5-T MRI system. In order to produce a 3D- model, axial and coronal T2-weighted turbo inversion recovery magnitude (TIRM) images and axial T2-weighted turbo spin echo (TSE) images orientated along the anal canal axis are used. Following image interpretation by a consultant radiologist, a standardised radiological report is produced. After surgical review of the imaging and report,...
