| Outline of Final Research Achievements |
The purpose of this study is to evaluate the detectability of arterial acute thrombus on R2* map by iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) IQ. As a result, the visual assessment showed that the detectability of acute thrombus on R2* map is comparable to that on T2*-weighted imaging (T2*WI). Regarding thrombus at distal internal carotid artery, the detectability on R2* map is superior to that on T2*WI. R2* map provide additional information to distinguish between embolism and atherosclerotic infractions. In addition, we could find the fact that the R2* map enables to detect acute intramural hematoma associated with cerebral artery dissection more effectively than T2*WI and earlier than high-resolution 3-dimensional T1-weighted imaging.
