急性脑梗死的CT脑灌注成像分析

Analysis of CT Brain Perfusion Imaging in Acute Cerebral Anfarction

目的对CT脑灌注成像技术诊断急性脑梗死的价值进行探讨。方法选择该院于2014年1月—2014年8月期间收治的急性脑梗死患者60例作为研究对象,该组患者均在1周内经CT平扫并复查确诊为脑梗死;患者入院后均在6 h内进行接受16层螺旋CT脑灌注成像,比较分析健侧正常区、半暗带区及脑梗死区的影像。结果通过统计、计算CT脑灌注成像数据可知,在CBF、CBV及MTT的平均值方面,脑梗死区与健侧区相比,差异有统计学意义(P<0.05);脑梗死区域、半暗带区及健侧区的CBV和MTT平均值呈逐渐下降趋势,而CBF成上升趋势。结论急性脑梗死可利用16层螺旋CT进行诊断,早期诊断效果良好,可为治疗提高准确的影像依据。

Objective To discuss the value of CT cerebral perfusion imaging technique in the diagnosis of acute cerebral infarction. Methods 60 patients with the acute cerebral infarction in our hospital in 2014 January to 2014 August as the research subjects, the groups of patients within 1 weeks after CT scan patients diagnosed as cerebral infarction; all the patients were performed within 6h received 16 slice spiral CT cerebral perfusion imaging, analysis and comparison of the contralateral normal region penumbra of cerebral infarction, and the image of the area.Results By statistics, calculating the CT cerebral perfusion imaging data shows that, in the average value of CBF, CBV and MTT, cerebral infarction area compared with the contralateral region, the difference was statistically（P〈0.05）; average value of cerebral infarction area, penumbra and contralateral regions of CBV and MTT decreased gradually, and CBF increased trend.Conclusion Acute cerebral infarction diagnosis can be carried out using 16 slice spiral CT, early diagnosis and good effect, can improve the imaging basis for proper treatment.
