作者对一个月内的375例做CT平扫检查的病人进行前瞻性研究,观察高密度大脑中动脉(MCA)出现的情况。观察的MCA部位相当于血管造影的M_1段。CT扫描层厚为8～10mm,检查机器为Philips体层扫描机60/TX CT,Siemans DR_3CT和GE 8800CT。高密度血管的定义为,血管的密度高于邻近颞叶和额叶脑组织密度。按此标准有13例诊断为高密度MCA的病人列入研究对象,
The authors conducted a prospective study of 375 patients who underwent CT scan in one month to observe the appearance of high-density middle cerebral artery (MCA). The observed sites of MCA corresponded to the M 1 segment of angiography. CT scan thickness 8 ~ 10mm, check the machine for the Philips tomography 60 / TX CT, Siemans DR_3CT and GE 8800CT. High-density blood vessels are defined as having a higher density of blood vessels than adjacent temporal and frontal lobe brain tissue. According to this standard 13 patients diagnosed with high-density MCA included in the study,
