Studies investigating the use of a preparatory microenema (ME) before scanning revealed that stool/gas and related artifacts in DWI can be reduced significantly [17, 18]. These coils send and receive radio waves, producing signals that are detected by the machine. After an initial series of scans, the contrast material will be injected into the intravenous line (IV). Scan quality can be impaired by artifacts, such as motion or susceptibility. Imposing fasting measures prior to the MR scan is another hypothesis on how to reduce bowel peristalsis. Kamrava et al.

However, ME is a bowel preparation technique for which available data (i) clearly indicates a positive effect on reduction of bowel peristalsis [18], (ii) strongly suggests improvement of DWI quality [5], (iii) where practically no side-effects are expected [30] and (iv) costs of the intervention are very low [5]. 2023 Springer Nature Switzerland AG.
