| Outline of Final Research Achievements |
[PURPOSE] To evaluate the maternal cerebral blood flow (CBF) change measured by arterial spin labeling (ASL) MRI in healthy subjects and in the patients with cerebrovascular disease (CVD). [SUBJECTS AND METHODS] ASL was performed to the healthy non-pregnant women (Group A, n=10), healthy pregnant women (Group B, n=8), and pregnant women with CVD, including 28 cases of moyamoya disease (MMD). 16 of MMD patients also had ASL-MRI at non-pregnant period. [RESULTS] In healthy groups, global CBF showed no significant change during pregnant period. Regional distribution of CBF was also similar between group A and B. Contrarily, the global CBF significantly dropped during pregnancy in the MMD patients. Among the MMD patients, 7 had multiple scans in different trimester of pregnancy and suggested that CBF dropped in the 3rd trimester. [CONCLUSIONS] The result indicated that cerebral hemodynamic may change differently between healthy women and the patients with MMD.
