【摘要】：目的對比容積CT數(shù)字減影血管造影(VCTDSA)和三維數(shù)字減影血管造影(3D-DSA)在顱內(nèi)動脈瘤診斷中的價值。方法疑似顱內(nèi)動脈瘤患者74例,男31例,女43例,平均72.3歲。均行VCTDSA和3D-DSA檢查,兩位評價者分析此兩項(xiàng)檢查的影像資料,記錄動脈瘤檢出的個數(shù)、部位及大小,并評價VCTDSA的診斷效能(包括敏感性、特異性、陽性預(yù)測值和陰性預(yù)測值)及兩種技術(shù)診斷動脈瘤的一致性。結(jié)果 3D-DSA檢出動脈瘤94個,VCTDSA檢出93個(評價者A檢出93個,評價者B 92個);評價者A檢出全部動脈瘤以及檢出3 mm動脈瘤的敏感性和陰性預(yù)測值較評價者B高,而兩者檢出≥3 mm動脈瘤的敏感性和特異性均為100%;在檢出動脈瘤個數(shù)、部位和大小三方面,3D-DSA和VCTDSA有很好的評價者間的一致性。結(jié)論 VCTDSA的動脈瘤檢出效能與3D-DSA相當(dāng),可以作為顱內(nèi)動脈瘤影像診斷的準(zhǔn)確方法。
[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.
