Assessment of MRI Tractography for Pelvic Floor Sphincter Analysis (TractoCA)
Inflammatory Bowel Disease, Neoplastic Pathology
About this trial
This is an interventional diagnostic trial for Inflammatory Bowel Disease focused on measuring Anatomy, Fiber tractography, Pelvic floor, Diffusion Tensor Imaging (DTI), Magnetic Resonance Imaging (MRI)

Arms of the Study
Arm 1
Arm 2
Experimental
Experimental
Pelvic MRI
Pelvic surgery
This arm involves patients undergoing a pelvic MRI. At the end of the planned sequence, but before any contrast agent injection: Acquisition of a an additional anatomical T2 SPACE sequence Acquisition of a tractography Diffusion Tensor Imaging (DTI) sequence All acquisitions will be done in an acceptable duration (less than 45 minutes)
This arm involves patients undergoing a pelvic surgery and coming for a postoperative MRI. An additional MRI is performed before the surgery and additional sequences are added to the planned postoperative MRI, at the end of the planned sequence, but before any contrast agent injection: Acquisition of a an additional anatomical T2 SPACE sequence Acquisition of a tractography Diffusion Tensor Imaging (DTI) sequence All acquisitions will be done in an acceptable duration (less than 45 minutes)
