Gas-induced susceptibility artefacts on diffusion-weighted MRI of the rectum at 1.5  T – Effect of applying a micro-enema to improve image quality

Conclusion Use of a preparatory micro-enema shortly before rectal EPI-DWI examinations performed at 1.5 T MRI significantly reduces both the incidence and severity of gas-induced artefacts, compared to examinations performed without bowel preparation.
