64排螺旋CT血管造影在颅内动脉瘤诊断中的应用及评价

The clinical Application of 64 Layers spiral CT Angiography in the diagnosis of intracranial Aneurysm

目的探讨64排螺旋CT血管造影(MSCTA)在颅内动脉瘤诊断中的应用价值。方法选取2011年1月—2013年12月我院收治的疑似颅内动脉瘤60例,同时行MSCTA、减影血管造影术(DSA)检查。其中50例行动脉瘤夹闭手术,对MSCTA、DSA检查结果与手术结果进行比较分析。结果 60例疑似颅内动脉瘤患者,MSCTA检查共检出61个动脉瘤,其中13例阴性,47例检出动脉瘤;DSA检查共检出59个动脉瘤,其中15例阴性。MSCTA和DSA均未检出的共有10例,其余50例经动脉瘤夹闭手术检出62个动脉瘤。MSCTA检查颅内动脉瘤的灵敏度、符合率、特异度、阳性预测值及阴性预测值均高于DSA。结论 MSCTA诊断颅内动脉瘤具有良好的灵敏度及特异度,可用于颅内动脉瘤的早期诊断。

Objective To explore the 64-slice spiral CT angiography（MSCTA）value in the diagnosis of intracranial aneurysms.Methods 60 cases of suspected intracranial aneurysms in our hospital were selected from January 2011 to December 2013,while the line MSCTA,subtraction angiography（DSA）examination were applied.50 routine aneurysm surgery on MSCTA,DSA findings were compared with surgical findings.Results 60 cases of patients with suspected intracranial aneurysms,MSCTA detected 61 aneurysms were,of which 13 cases were negative,47 cases were aneurysms;DSA examination detected 59 aneurysms,of which 15 cases were negative.MSCTA and DSA were not detected in a total of 10 cases,the remaining 50 cases of aneurysm surgery detected 62 aneurysms.MSCTA check the sensitivity of intracranial aneurysms,compliance rate,specificity,positive predictive value and negative predictive values were higher than the DSA.Conclusion MSCTA diagnosis of intracranial aneurysms with good sensitivity and specificity,and can be used for early diagnosis of intracranial aneurysms.
