中风中经络辨证类型与CT、MRI影像诊断的关系

目的：研究中风中经络5种分型CT与MRI影像学特点。方法：对97例中风中经络患者采用辨证分型并进行CT与MRI扫描,检查病灶分布部位及病灶大小,分析不同中风中经络分型CT与MRI特点。结果：在病灶分布部位上,中风中经络不同分型在CT与MRI表现上较为接近。其中,风痰阻络证病灶主要集中在基底节区（CT：67.6%;MRI：66.7%）;气虚血瘀证病灶主要集中在放射冠区域（CT：50.0%;MRI：50.7%）;两者CT病灶分布差异具有统计学意义（P〈0.05）。在病灶大小特点上,痰热腑实证CT（84.6%）与MRI（84.6%）病灶均以大片状病灶为主,而其余4型CT与MRI病灶均主要为小片状病灶。痰热腑实证与其余4型CT、MRI病灶大小分布差异有统计学意义（P〈0.05）。结论：中风中经络5种分型中部分分型在CT、MRI影像学具有一定的特点,风痰阻络证病灶部位多集中于基底节区,气虚血瘀证病灶以放射冠区较为多见,痰热腑实证以大片状梗死灶为主,其余4型以小片状梗死灶为主。

Relationship between Diagnosis of CT and MRI and Syndromes Identification of Stroke with striking the channels and network vessels

Objective： To study the CT and MRI imaging features in 5 types of syndromes of Stroke with striking the channels and network vessels. Methods： The 97 patients of stroke striking the channels and network vessels were identified for syndrome differentiation and tested with CT and MRI, to observe the lesions location and lesion size, in order to analyze the CT and MRI characteristics. The lesion distribution, the CT and MRI performance is close in different syndromes. Wind phlegm syndrome were mainly concentrated in the basal ganglia （CT：67.6%; MRh66.7%）; Qi deficiency and blood stasis syndrome were mainly concentrated in the corona region （CT：50.0%; MRI：50.7%）; there were significant differences between CT distribution of lesions （P〈0.05）. In lesion size characteristics, CT （84.6%） and MRI （84.6%） lesions of phlegm heat and viscera repletion syn- drome were dominated by big shape of lesions, while the CT and MRI lesions of the remaining 4 type were mainly patchy le- sions. The CT and MRI lesion size distribution difference between phlegm heat and viscera repletion syndrome and the remaining 4 type showed statistical significance （P〈0.05）. Conclusion： Some syndromes of the 5 types of Stroke with striking the channels and network vessels showed some characteristics on CT, MRI image; wind phlegm syndrome lesions are more concentrated in the basal ganglia; Qi deficiency and blood stasis syndrome lesion to the corona radiata is common; the main performance of phlegm heat and viscera repletion syndrome was infarction big shape, and patch infarction foci of the other 4 types.
