【摘要】：目的探讨64层螺旋CT脑灌注成像在急性脑梗死诊断中的临床应用价值。方法选择我院2013年6月—2014年10月收治的急性脑梗死92例作为研究对象,应用东芝公司生产的64层螺旋CT脑灌注成像观察患者梗死部位及梗死灶大小,并观察比较患者脑梗死区、缺血半暗带区和健侧区脑血容量(CBV)、脑血流量(CBF)、平均通过时间(MTT)。结果 CT检查发现本组梗死部位分别为基底核23例,额叶20例,颞叶18例,枕叶16例,顶叶15例;梗死灶大小分别为中度梗死33例,小梗死30例,腔隙性梗死29例。缺血半暗带区、健侧区及脑梗死区CBV、CBF及MTT比较差异均有统计学意义(P0.05)。CBV水平缺血半暗带区高于健侧区、脑梗死区;CBF水平健侧区高于缺血半暗带区和脑梗死区,脑梗死区低于缺血半暗带区;MTT脑梗死区和缺血半暗带区高于健侧区,缺血半暗带区低于脑梗死区,差异均有统计学意义(P0.05)。结论 64层螺旋CT脑灌注成像可较为准确地显示急性脑梗死部位和缺血半暗带、梗死灶大小,评价脑组织血流灌注情况。
[Abstract]:Objective to evaluate the clinical value of 64-slice spiral CT perfusion imaging in the diagnosis of acute cerebral infarction. Methods 92 patients with acute cerebral infarction treated in our hospital from June 2013 to October 2014 were studied. The infarct location and infarct size were observed by 64-slice spiral CT perfusion imaging produced by Toshiba Company. The cerebral blood volume (CBV), cerebral blood flow (CBF) and mean transit time (MTT) in cerebral infarction, ischemic penumbra and contralateral regions were observed and compared. Results CT examination showed that the infarct location was basal nucleus in 23 cases, frontal lobe in 20 cases, temporal lobe in 18 cases, occipital lobe in 16 cases, parietal lobe in 15 cases, infarction size was moderate in 33 cases, small infarction in 30 cases, lacunar infarction in 29 cases. There were significant differences in CBF and MTT in ischemic penumbra, contralateral area and cerebral infarction area (P0.05). CBV level in ischemic penumbra was higher than that in contralateral area, and the level of CBF in healthy side was higher than that in ischemic penumbra and cerebral infarction. The cerebral infarction area was lower than the ischemic penumbra area, the MTT cerebral infarction area and the ischemic penumbra area were higher than the healthy side area, the ischemic penumbra area was lower than the cerebral infarction area, the difference was statistically significant (P0.05). Conclusion 64-slice spiral CT perfusion imaging can accurately display the location of acute cerebral infarction and ischemic penumbra, the size of infarct, and evaluate the perfusion of cerebral tissue.
