摘　　要：目的:探讨二维超声联合微血管血流成像(MV-flow)对睾丸结核的诊断价值。方法:选择2023年1月至12月在郑州大学第一附属医院因阴囊疼痛、坠胀,或伴有阴囊肿块就诊,疑似睾丸结核的91例患者为研究对象。均行二维超声检查、彩色多普勒血流显像(CDFI)和MV-flow。以病理结果为金标准,比较二维超声联合MV-flow及二维超声联合CDFI诊断睾丸结核的效能,同时计算血流像素占比。另外选取20例疑似睾丸结核患者,通过MV-flow获取血管指数(VI),采用同类相关系数(ICC)评估MV-flow检测结果的一致性。结果:91例患者中共有80例病理确诊为睾丸结核。二维超声联合MV-flow诊断睾丸结核的敏感度、特异度、准确度分别为96.3%、54.6%和91.2%,高于二维超声联合CDFI(87.5%、18.2%、79.1%)。MV-flow睾丸内血流像素占比高于CDFI[(2.13±0.81)%vs(1.86±0.70)%,P=0.360]。VI在观察者内和观察者间的一致性良好[ICC(95%CI)分别为0.874(0.683~0.950)、0.945(0.860~0.978)]。结论:相比二维超声联合CDFI,二维超声联合MV-flow对睾丸结核的诊断效能更高。Aim:To explore diagnostic value of two-dimensional ultrasound combined with microvascular blood flow imaging(MV-flow)for testicular tuberculosis.Methods:Totally 91 patients with suspected testicular tuberculosis,who accepted two-dimensional ultrasound,color Doppler flow imaging(CDFI)and MV-flow imaging in the First Affiliated Hospital of Zhengzhou University from January to December 2023 were collected.Using pathological results as the gold standard,the diagnostic efficacy of two-dimensional ultrasound combined with MV-flow and two-dimensional ultrasound combined with CDFI was evaluated.Blood flow pixel ratio of MV-flow and CDFI was calculated.Another 20 patients were collected and intra-class correlation coefficient(ICC)was obtained based on vascular index(VI)from MV-flow.Results:A total of 80 out of 91 patients were diagnosed with testicular tuberculosis.The diagnostic sensitivity,specificity,accuracy of two-dimensional ultrasound combined with MV-flow were 96.3%,54.6%,91.2%,higher than those(87.5%,18.2%,79.1%)of two-dimensional ultrasound combined with CDFI.Blood flow pixel ratio of MV-flow was higher than that of CDFI[(2.13±0.81)%vs(1.86±0.70)%](P=0.360).The diagnostic consistency of VI within and between observers was favorable[ICC(95%CI)was 0.874(0.683-0.950)and 0.945(0.860-0.978)].Conclusion:Two-dimensional ultrasound combined with MV-flow have higher diagnostic efficacy for testicular tuberculosis than two-dimensional ultrasound combined with CDFI.
