【摘要】 目的 对比Brilliance 256层iCT灌注成像、CT平扫、常规头颅CTA诊断缺血性脑病的效果。方法 回顾性分析2019年2月至2020年8月40例缺血性脑病患者临床资料，均使用同一台CT机进行CT平扫、常规头颅CTA和Brilliance 256层iCT灌注成像，记录三种影像学方法 检查结果，通过一致性分析三种影像学方法 诊断缺血性脑病的价值。结果 40例缺血性脑病CT平扫后，31例(77.50%)患者发现42个缺血病灶。40例缺血性脑病行常规头颅CTA后，共发现病变血管52处。40例缺血性脑病行Brilliance 256层iCT灌注成像后，病变中心区CBV、CBF显著低于病变对侧镜像区，差异有统计学意义(P<0.05)；病变中心区MTT、TTP显著高于病变对侧镜像区，差异有统计学意义(P<0.05)。40例缺血性脑病患者，行CT平扫检查阳性31例，Kappa=0.541；行常规头颅CTA检查阳性33例，Kappa=0.543；行Brilliance 256层iCT灌注成像阳性35例，Kappa=0.722。结论 Brilliance 256层iCT灌注成像诊断缺血性脑病临床价值较高。更多还原

【Abstract】 Objective Compare the effects of Brilliance 256-slice iCT perfusion imaging, CT plain scan, and conventional head CTA in the diagnosis of ischemic encephalopathy. Methods A retrospective analysis of 40 patients with ischemic encephalopathy who were diagnosed and treated in our hospital from February 2019 to August 2020. All patients used the same CT machine for CT plain scan, conventional cranial CTA and Brilliance 256-slice iCT perfusion imaging. First record the results of plain CT scan,conventional head CTA and Brilliance 256-slice iCT perfusion imaging(comparing 40 cases of ischemic encephalopathy brain perfusion parameters), then compare the difference in radiation dose between CT plain scan and Brilliance 256-slice iCT perfusion imaging, and finally pass the same To analyze the value of plain CT scan, conventional cranial CTA and Brilliance 256-slice iCT perfusion imaging in the diagnosis of ischemic encephalopathy. Results After CT scan of 40 cases of ischemic encephalopathy,31 cases(77.50%) found 42 ischemic lesions. After 40 cases of ischemic encephalopathy underwent conventional cranial CTA, 52 diseased blood vessels were found.After 40 cases of ischemic encephalopathy underwent Brilliance 256-slice iCT perfusion imaging, the CBV and CBF in the central area of the lesion were significantly lower than those in the contralateral mirror area, the difference was statistically significant(P<0.05); the MTT and TTP in the central area of the lesion were significantly higher than In the contralateral mirror area of the lesion, the difference was statistically significant(P<0.05).Among 40 patients with ischemic encephalopathy, 31 cases were positive on plain CT scan,Kappa=0.541. Among the 40 patients with ischemic encephalopathy, 33 cases were positive by conventional head CTA, and Kappa=0.543. Among 40 patients with ischemic encephalopathy, Brilliance 256 35 cases were positive for slice iCT perfusion imaging, Kappa=0.722. Conclusion Brilliance 256-slice i CT perfusion imaging in the diagnosis of ischemic encephalopathy can instantly reflect the changes in cerebral hemodynamics in patients with ischemic encephalopathy, with high diagnostic accuracy and low harm to the human body, which is important for clinical diagnosis and prognosis evaluation The value of the clinic should be paid attention to.更多还原
