Outline of Final Research Achievements

According to the phantom experiment, we found that the artifacts of intestinal gasses have a significant impact on the image quality of the SWI images. The pelvic MR imaging with SWI was performed for three volunteers with and without the drug which drains intestinal gasses. As a result, the images of the volunteers with the drug demonstrated fewer artifacts than those without drugs.
In conclusion, the pelvic MR imaging with SWI may require premedication with the drug which drains intestinal gasses in order to reduce the artifacts of intestinal gasses.
