The rate of cerebral infarction associated with white matter lesion(WML)and brain atrophy in VD group was higher than that of NVD group. Conclusion :The factors that mosts…
结论：血管性痴呆与梗塞部位及是否存在脑白质变性和脑萎缩有关。
The lesion is well demarcated (Figures 1 ~ 4 in the first batch) and found in the white matter only. The cerebral cortex is spared (Figure 3).
这种疾病境界清楚(第一组图1 -4)，而且只发生于大脑白质，皮质未累及(图3)。
Results:Signal normal counter white matter was almost turn to base line at the end of first pass, but lesion and perilesion of gliomas remain had some signal reduced.
结果：对侧正常白质信号于首过期末几乎恢复至基线，肿瘤区则仍有不同程度下降；
Standardized uptake values (SUVs) and perfusion levels of the lesion and the normal white matter were measured in FDG-PET and ASL studies, respectively.
PET及ASL研究中，标准化摄取评价（SUVs）、病灶环流水平及正常脑白质被各自检测。
Lesion vs. white matter and lesion vs. CSF contrast of acute infarct were superior to those of old infarcts on DWI, and the ADC of acute infarct lesions were much lower than that of old lesions.
DWI图像上，急性腔隙性脑白质梗死病灶与脑白质、病灶与脑脊液对比度明显高于陈旧病灶，ADC则明显低于陈旧病灶，有助于区分新陈腔隙性梗死。
The ratio of FDG uptake of the lesion to normal white matter in PET and the ratio of cerebral blood perfusion of the lesion to normal white matter also were compared.
PET是病灶FDG摄取与正常脑白质比率进行比较，ASL是病灶大脑血环流量与正常脑白质比率进行比较。
The ratio of FDG uptake of the lesion to normal white matter in PET and the ratio of cerebral blood perfusion of the lesion to normal white matter also were compared.
PET是病灶FDG摄取与正常脑白质比率进行比较，ASL是病灶大脑血环流量与正常脑白质比率进行比较。
