Summary
Brief summary (as posted)
The presence of rectal gas can cause distortion at air-tissue interfaces on diffusion-weighted images (DWI) of prostate MRI and reduce image quality due to these susceptibility artifacts. Small catheter placement in the rectum before MRI is one of the ways that is advocated in PI-RADS v2 guidelines to reduce rectal gas. The goal of this study is to prospectively evaluate the effect of small catheter placement on artifacts on diffusion weighted images and to see whether it improves diagnostic accuracy.

Show eligibility criteria text
Inclusion Criteria: * willing to participate in the study by giving written informed consent. * male subjects aged between 45 to 80 years. * scheduled for a prostate MRI due to clinical suspicion of prostatic carcinoma (elevated prostate specific antigen (PSA) levels in blood and/or abnormal digital rectal examination (DRE)), staging, follow-up or active surveillance. * good health condition based on medical history, physical examination and vital sign measurements. Exclusion Criteria: * has a contra-indication for MRI (claustrophobia, non-compatible metallic implants). * has a prior history of hip prosthesis. * has any condition, physical, mental, familial or sociological, that could impede compliance with the study protocol and further follow-up. This is not an absolute contra-indication, but should be discussed with patient prior to registration in the trial.
