We retrospectively investigated whether administration of 1 mg of intramuscular (IM) glucagon to decrease bowel peristalsis prior to prostate MRI decreases motion artifact. Two blinded, independent readers reviewed MRI prostate studies of 25 and 26 patients who did and did not receive glucagon, respectively, for motion-related blurring of the prostate, bowel, and lymph nodes on a five-point Likert scale. No significant difference was observed in all categories. Although European Society of Uroradiology (ESUR) and American College of Radiology guidelines recommend using antiperistaltic agents for prostate MRI, our results suggest that IM glucagon may not be necessary.
