多层螺旋CT血管成像在诊断急性缺血性脑卒中的临床应用价值

摘要

目的:探究头颈部多层螺旋CT血管成像技术对急性缺血性脑卒中 (AIS) 的诊断价值.方法:选取医院收治的173例AIS患者, 均接受溶栓、血管内取栓、支架等治疗, 并于治疗前后分别使用多层螺旋CT血管成像 (CTA) 及灌注成像 (CTPI) 进行检查, 对CTA获得图像进行处理, 分析不同成像方法对AIS患者的诊断价值.结果:CTPI扫描中脑血流量 (CBF) 和平均通过时间 (MTT) 的诊断准确率及灵敏度明显高于CT平扫, 其差异有统计学意义 (x2=8.694, x2=9.430, x2=24.967, x2=42.564;P<0.05) ;CTA扫描中颅内动脉的诊断准确率及灵敏度均高于CT平扫, 差异有统计学意义 (x2=10.221, x2=45.983;P<0.05) ;颈内动脉CTA诊断准确率低于CT平扫, 差异有统计学意义 (x2=5.026, P<0.05) ;CTPI扫描和CTA两种诊断方法的特异度与CT平扫比较, 差异无统计学意义 (x2=0.023, x2=0.878;P>0.05) .结论:经头部多层螺旋CTA检查和CTPI检查, 均可较好的对AIS进行诊断, 为临床疾病的治疗和预防提供科学、有效依据支持, 值得临床应用.%Objective:To investigate the value of multi-slice spiral CT angiography (CTA) in the diagnosis and treatment of acute ischemic stroke (AIS) .Methods:A total of 173 patients with AIS admitted to our hospital were enrolled in this study.All of patients were treated with thrombolytic therapy, intravascular taking away thrombus, stent treatment and others treatment.Multi-slice spiral CTA and CT perfusion imaging (CTPI) were used to implement examination before and after treatment.And the images obtained by CTA were further processed.In addition, the values of different imaging methods in the diagnosis and treatment for patients with AIS were analyzed.Results:The diagnostic accuracy■P>0.05) , respectively.Conclusion:According to the results of the study, the multi-slice spiral CTA examination and CTPI examination can better diagnose AIS, and they can provide scientific and effective basis in supporting treatment and prevention for clinical disease.Therefore, they are worthy in clinical application.
