【摘要】 目的探讨多层螺旋CT扫描成像诊断颅内动脉瘤患者的临床价值及影像学特征。方法选取2016年1月至2018年12月就诊于淮南市第一人民医院的高度疑似颅内动脉瘤患者共58例作为研究对象,入院后给予所有患者多层螺旋CT扫描成像诊断,以数字减影血管造影(DSA)诊断结果为金标准,评估多层螺旋CT诊断颅内动脉瘤中准确率、特异度及灵敏度,分析颅内动脉瘤的CT成像特征。结果 CT与DSA诊断准确率、特异度及灵敏度比较差异无统计学意义(P>0.05);两种检查方法病灶检出符合率比较差异无统计学意义(P>0.05)。结论多层螺旋CT应用于颅内动脉瘤诊断中具有较高的准确率、特异度及灵敏度,诊断安全性高,可重复性好,能较为清晰全面地显示病灶位置、形态和大小,可作为颅脑动脉瘤早期诊断方法之一。更多还原

【Abstract】 Objective To investigate the clinical value and imaging features of multi-slice spiral CT imaging in the diagnosis of intracranial aneurysms.Methods 58 patients with suspected intracranial aneurysms from January 2016 to December 2018 were selected as the study subjects.After admission,all patients were diagnosed by multi-slice spiral CT scanning.The accuracy,specificity and sensitivity of multi-slice spiral CT in the diagnosis of intracranial aneurysms were evaluated based on the diagnostic results of digital subtraction angiography(DSA),and the intracranial aneurysms were analyzed.CT imaging features.Results There was no significant difference in accuracy,specificity and sensitivity between CT and DSA(P>0.05);there was no significant difference in the coincidence rate of lesion detection between the two methods(P>0.05).Conclusion MSCT has high accuracy,specificity and sensitivity in the diagnosis of intracranial aneurysms.It has high diagnostic safety,good repeatability and can clearly and comprehensively display the location,shape and size of the lesions.It can be used as one of the early diagnostic methods of intracranial aneurysms.更多还原
