【摘要】：目的对比容积CT数字减影血管造影(VCTDSA)和三维数字减影血管造影(3D-DSA)在颅内动脉瘤诊断中的价值。方法疑似颅内动脉瘤患者74例,男31例,女43例,平均72.3岁。均行VCTDSA和3D-DSA检查,两位评价者分析此两项检查的影像资料,记录动脉瘤检出的个数、部位及大小,并评价VCTDSA的诊断效能(包括敏感性、特异性、阳性预测值和阴性预测值)及两种技术诊断动脉瘤的一致性。结果 3D-DSA检出动脉瘤94个,VCTDSA检出93个(评价者A检出93个,评价者B 92个);评价者A检出全部动脉瘤以及检出3 mm动脉瘤的敏感性和阴性预测值较评价者B高,而两者检出≥3 mm动脉瘤的敏感性和特异性均为100%;在检出动脉瘤个数、部位和大小三方面,3D-DSA和VCTDSA有很好的评价者间的一致性。结论 VCTDSA的动脉瘤检出效能与3D-DSA相当,可以作为颅内动脉瘤影像诊断的准确方法。
[Abstract]:Objective to compare the value of volume CT digital subtraction angiography (VCTDSA) and three-dimensional digital subtraction angiography (3D-DSA) in the diagnosis of intracranial aneurysms. Methods 74 cases of suspected intracranial aneurysms, 31 males and 43 women, averaging 72.3 years old. All of them were examined by VCTDSA and 3D-DSA, and two of the two patients were analyzed the two examination images and recorded the aneurysm examination. The number, location, size and diagnostic efficacy of VCTDSA (including sensitivity, specificity, positive predictive value and negative predictive value) and the consistency of two kinds of aneurysms were evaluated. Results 3D-DSA detected 94 aneurysms and 93 VCTDSA (93 of the evaluators were detected by A and 92 of the evaluators); the evaluator A detected all the aneurysms and detected 3 of the aneurysms. The sensitivity and negative predictive value of MM aneurysm were higher than that of the evaluator B, and the sensitivity and specificity of both of them to 3 mm aneurysms were 100%. In detecting the number of aneurysms, location and size three, 3D-DSA and VCTDSA had a good consistency between the evaluators. Conclusion the detection efficiency of the aneurysm of VCTDSA is equivalent to that of 3D-DSA and can be used as a intracranial aneurysm. An accurate method of imaging diagnosis of aneurysm.
