Abstract

AbstractIn MR angiography, which is effective for screening of aneurysms, investigation for the quality of high‐resolution angiography method using the combination of asymmetric measurement with half scan reconstruction are presented. In addition to avoiding the flow void by the asymmetric measurement, it was found that there were improvements of: (1) blood contrast by isolation of small vessels and static regions; (2) blood continuation by interpolation in 3‐dimensional space; and (3) relative S/N of small vessels with the increasing resolution. Experimental results show that good contrast image is obtained by this method with no penalty of scanning time.
