摘要
目的分析在肾动脉狭窄诊断中,应用多排CT血管探针技术(vessel probe,VP)的诊断价值。方法纳入2017年1月—2023年1月在本院接受检查的疑似肾动脉狭窄患者110例,均对其进行VP检查、CT血管造影技术(CTA)检查,并将结果与金标准减影血管造影(DSA)相对比,计算VP检查的诊断效能。结果在110例疑似患者中,金标准方式共检出阳性50例,阴性60例;VP检查共检出真阳性48例,真阴性46例,诊断效能为:灵敏度96.00%(48/50);特异度为76.67%(46/60);诊断符合率为85.45%(94/110)。CTA检查诊断灵敏度为94.00%(47/50),特异度为73.00%(44/60),符合率为82.73%(91/110),VP检查与CTA检查比较,差异无统计学意义(P>0.05)。结论在肾动脉狭窄的诊断过程中,采用CTA检查能够获取具备高时间分辨率与空间分辨率的图像。通过运用VP检查可以精确有效地检测斑块的范围、性质以及狭窄程度。此外,对比VP检查与CTA检查在肾动脉狭窄诊断中的应用,两者在检出率方面并未展现出显著差异。
Objective To analyze the diagnostic value of multi slice spiral CT vascular probe technology in diagnosis of renal artery stenosis.Methods A total of 110 patients with suspected renal artery stenosis who were examined in our hospital from January 2017 to January 2023 were included.All of them were examined by multi-slice spiral CT vascular probe technique and CT angiography technique,and the results were compared with the gold standard(DSA)to calculate the diagnostic efficiency of multislice spiral CT vascular probe technique.Results:Among 110 suspected patients,50 positive cases and 60 negative cases were detected by gold standard method.A total of 48 true positive cases and 46 true negative cases were detected by vascular probe technique.The diagnostic efficacy of vascular probe was as follows:sensitivity was 96.00%(48/50);The specificity was 76.67%(46/60).The diagnostic coincidence rate was 85.45%(94/110).The diagnostic sensitivity of CT angiography was 94.00%(47/50),the specificity was 73.00%(44/60),and the coincidence rate was 82.73%(91/110).Compared with CT angiography,there was no significant difference(P>0.05).Conclusion In the diagnosis of renal artery stenosis,CT angiography can obtain high temporal and spatial resolution images,and vascular probe technology can effectively detect the extent,nature and degree of plaque stenosis.There is no significant difference in the detection rate of renal artery stenosis between multi-slice spiral CT and CT angiography.
