摘要
目的:探讨CT血管造影(CT coronary angiography,CTA)及磁共振血管成像(magnetic resonance angiography,MRA)对大脑中动脉闭塞性病变(middle cerebral artery occlusive diseases,MCAOD)的临床诊断价值,并进行对比。方法:医院收治的150例脑血管病患者(300条受检血管),均经CT血管造影,并结合多平面重组、曲面重组等方法来显示颅内脑动脉狭窄情况,7 d内进一步行MRA检查,并将CTA与MRA的显示情况和结果进行对照分析。结果:在150例患者300条受检的大脑中动脉中,经MRI检查为正常或轻度、中度、重度狭窄的血管条数分别为76、114、110条;经CTA检查正常或轻度、中度和重度的血管条数为66、94、90条,两组差异具有统计学意义,P<0.01。MRA检查还得到3组之间的平均收缩峰流速,差异有统计学意义,P<0.01,以重度狭窄流速最快;重度狭窄的CTA表现为主动脉壁呈新月型或环形增厚。结论:CTA和MRA是诊断大脑中动脉闭塞性病变准确性较好的无创性检查方法,而检测的侧重面不同,所以应将两者结合以提高诊断的准确率。
Objective To explore and compare the diagnostic values of CT coronary angiography（CTA） and magnetic resonance angiography（MRA） for middle cerebral artery occlusive diseases（MCAOD）. Methods Totally 150 patients with cerebrovascular diseases underwent CT angiography, multi-planar reformation, surface reformation and etc to display intracranial artery stenosis, with 300 pieces of vessels involved in. MRA was performed for the 150 patients within 7 days,and then the results by CTA were compared with those by MTA. Results The numbers of mild, moderate and severe stenosis shown by MTA were 76, 114 and 110 respectively, and those by CTA were 66, 94 and 90 respectively, with significant difference between the results by MTA and by CTA（P〈0.01）. The mean values for systolic blood flow velocity of the three kinds of patients were obtained by MTA, with statistical differences between them（P〈0.01）, and the highest velocity was found in the patients with severe stenosis. CTA showed that the patients with severe stenosis were characterized by crescent-like or circular thickening. Conclusion CTA and MTA can be both used for noninvasive detection of MCAOD with different emphases, and thus have to be combined to promote the diagnosis.
