Synopsis

Keywords: Gastrointestinal Motility

Motivation: Further examples and methodology extending our abstract to the Unmet Needs Challenge on Gastrointestinal Motility [1].

Goal(s): Localisation of regions of bowel that are affected by adhesions.

Approach: We previously proposed that regions of reduced shear may correspond to bowel motility hindered by adhesions [1]. Shear was calculated from coronal cine frames and presented as red colour overlays. Here we present further examples and add a linked-cursor that links regions of restricted motility to impressions of tethering in axial structural images, e.g. angulated bowel loops.

Results: Descriptive exemplars are presented.

Impact: Adhesions cannot be directly seen in MRI but tethering may be apparent in structural and motility images. The proposed post-processing methods use readily available MR sequences and Results suggest further investigation to validate observations and to assess potential clinical benefit.
