摘要:
目的 探讨多层螺旋CT血管造影(MSCTA)诊断动脉粥样硬化性肾动脉狭窄(ARAS)的必要性和可靠性。方法 选取82例曾做过数字减影血管造影(DSA)的ARAS患者行肾动脉MSCTA,将所获得的图像数据进行多平面重建、最大密度投影法重建、容积重建和表面阴影遮盖法重建,将结果与DSA进行对比分析。结果 ①MSCTA发现狭窄血管95支,其中85支经DSA证实(10支为假阳性),符合率为89%,假阳性率为6.1%。②密度投影法重建+容积重建显示狭窄血管率达到100%。结论 MSCTA是筛选ARAS的可靠方法。
Abstract:
Objective To study the reliability and necessity of multi-spiral computed tomography angiography(MSCTA) for non-invasive examination of patients with atherosclerotic renal artery stenosis(ARAS). Method Eighty-two ARAS patients who had taken intraarterial digital subtraction angiography were performed with MSCTA. The obtained image data were analyzed in MPR, MIP, VR and SSD with multi-spiral CT at certain condition and were compared with digital substrction angiography(DSA) images. Results ① MSCTA visualized 95 renal artery stenosis on DSA, 85 of which were detected coordinate(10 were false-positive cases). The concordance rate of DSA and MSCTA was 89%, and the false positive rate was 6.1%. ② The intensity projection reconstruction and volume reconstruction perfectly showed stenosis. Conclusion MSCTA is helpful to accurately display the renal artery variation and lesions, and is also a reliable and accurate screening modality for the evaluation of patients with ARAS.
