脑灌注显像可以反映脑组织血流分布，对诊断脑血管疾病是一种灵敏、有效的影像检查手段。以往的脑灌注显像分析只是通过图像密度或颜色变化定性观察脑血流变化，易受主客观因素影响，而直观局部脑血流量变化，客观、准确地定量评价脑血流实际状态、受损程度，则有重要的临... Cerebral perfusion imaging can reflect the distribution of brain blood flow, the diagnosis of cerebrovascular disease is a sensitive and effective means of image examination. In the past, brain perfusion imaging analysis only qualitatively observed cerebral blood flow changes by image density or color change, and was easily affected by the subjective and objective factors. However, the visual local cerebral blood flow changes were objectively and accurately evaluated and the actual state of cerebral blood flow was quantitatively evaluated and impaired Degree, then there is an important Pro ...
