| [ Summary ] |
The utility of CT colonography has been reported on in Europe and America since CT colonography was introduced in 1994 by Vining. However, there are some problems with this modality, such as pretreatment, pain during examinations and exposure to radiation. Dark lumen MR colonography, in which the fecal tagging method is used for large bowel screening, may help eliminate these problems, as reported by Weishaupt. By this report, examples of experiments and examining the utility of dark lumen MR colonography, using the fecal tagging method are reported. In addition, rapid progress has been made in imaging diagnostic method. It is thought that high resolution virtual MR colonography will soon be developed. |
