Abstract: AIM: We aimed to develop an intuitive, interactive, 3D MRI modelling technique to
produce a 3D image of fistula in ano. METHOD: The 3D model is created from standard 2D MRI sequences to produce an image
which is anatomically correct. Individual muscle and soft tissue layers are
extracted from T1 weighted sequences and fistula pathology from STIR sequences,
to produce two separate volumes. These are then fused using post processing
software (Vitrea Workstation version 6.3) to
generate a 3D model. RESULTS: The final 3D model is incorporated into a PDF file which has an integrated
CAD viewer allowing the surgeon to rotate it in any direction during pre
operative planning or whilst in theatre. CONCLUSION: As an adjunct to 2D MRI images and the associated radiology report, this
model communicates better the fistula anatomy to the clinician and should be
particularly useful in complex cases. This article is protected by copyright.
