慢性脑供血不足患者脑血流变化的多层螺旋CT灌注成像研究

Multi-Slice Spiral CT Perfusion Imaging of Cerebral Blood Flow in Patients with Chronic Cerebral Insufficiency

目的:探究慢性脑供血不足患者脑血流变化的多层螺旋CT灌注成像。方法:将慢性脑供血不足患者作为研究对象,收治时间为2021年2月至2022年2月,对所有患者均实施多层螺旋CT灌注成像诊断,分析诊断结果以证明多层螺旋CT灌注成像对慢性脑供血不足患者脑血流变化进行观察的价值。结果:CCCI组的TTP、CBV、CBF指标和非CCCI组相比,差异有统计学意义(P<0.05)。联合诊断的阳性率显著高于单一诊断阳性率(P<0.05)。联合诊断的敏感度、准确度、特异度显著高于单一诊断(P<0.05)。结论:慢性脑供血不足患者脑血流变化实施多层螺旋CT灌注成像,取得显著诊断价值。

Objective:To investigate the changes of cerebral blood flow in patients with chronic cerebral insufficiency by multi-slice spiral CT perfusion imaging.Methods:Patients with chronic cerebral insufficiency were selected as the subjects of this study.The treatment time was from February 2021 to February 2022.All patients were diagnosed with multi-slice spiral CT perfusion imaging.The diagnostic results were analyzed to prove the value of multi-slice spiral CT perfusion imaging in observing the changes in cerebral blood flow in patients with chronic cerebral insufficiency.Results:TTP,CBV,and CBF in the CCCI group were significantly different from those in the non-CCCI group(P<0.05).The positive rate of combined diagnosis was significantly higher than that of single diagnosis(P<0.05).The sensitivity,accuracy,and specificity of combined diagnosis were significantly higher than those of single diagnosis(P<0.05).Conclusion:Multi-slice spiral CT perfusion imaging has significant diagnostic value in patients with chronic cerebral insufficiency.
