急性脑梗死后失语症的MRI影像学研究

Analysis of MRI Manifestation with Aphasia after Acute Cerebral Infarction

目的:应用MRI检查确定急性脑梗死后失语症类型与脑梗死部位之间的关系。方法:对68例急性脑梗死后具有失语症表现患者应用汉语失语成套测验中的利手评定标准进行利手判定和汉语失语症检查进行失语症的分类,用头颅MRI确定患者的脑梗死部位及病灶体积。结果:68例急性脑梗死失语症患者均为右利手,失语症类型分别为完全性失语18例,运动性失语25例,感觉性失语7例,传导性失语7例,经皮质运动性失语7例,命名性失语4例。累及经典语言中枢的有32例,36例为非语言中枢受累。结论:急性脑梗死失语症类型与传统的失语症解剖定位不完全符合,非语言中枢梗死也可引起失语症。

Aim： To reveal the relationship between aphasia and infarct lesion defined by MRI through analysis of 68 patients with aphasia performance after acute cerebral infarction. Methods： The potential patients were evaluated by the hand evaluation standard of Aphasia Battery of Chinese. Chinese Aphasia Examination was applied to classify the type of aphasia. The lesion site and volume of cerebral infarction in patients were determined by MRI. Results： All 68 cases of aphasia patients were right-handed. There were 18 global aphasia（GA） cases, 25 broca aphasia（BA） cases, 7 wernicke aphasia（WA） cases, 7 conduction aphasia cases, 7 transcortical motor aphasia（TCM） cases and 4 anomic aphasia（AA） cases. There were 32 cases with the classic language center and 36 cases with non-language center. Conclusion： The aphasia types were not agreed with the traditional aphasia anatomical localization, and the non-language center may also cause aphasia.
