超声造影在肾、膀胱占位性病变中的应用

目的探讨超声造影剂声诺维(SonoVue)及对比脉冲序列成像技术(CPS)在肾、膀胱占位性病变中的应用价值。方法对88例二维超声发现肾、膀胱异常回声结节,可疑肾、膀胱占位性病变的患者行实时超声造影,造影结果与病理对照。结果造影提示肾恶性肿瘤41例,良性肿瘤8例,膀胱恶性肿瘤35例,膀胱良性病变4例。病理证实为肾恶性肿瘤38例,良性肿瘤11例,膀胱恶性肿瘤34例,膀胱良性病变5例。超声造影误诊4例。诊断肾、膀胱占位性病变敏感性、特异性和准确性分别为94.73%、75.00%、95.45%。结论超声造影在诊断肾、膀胱占位性病变及鉴别肿瘤的良恶性方面有重要的临床使用价值。

The application of contrast-enhanced ultrasound in the diagnosis of renal and bladder occupied lesions

Purpose To explore the value of ultrasound contrast agent SonoVue and Cadence Pulse sequencing(CPS)in diagnosing renal and bladder occupied lesions.Methods Conventional and contrast-enhanced ultrasound were performed on 88 suspected renal and bladder occupied lesions.The results were compared with that of pathology.Results Contrast-enhanced ultrasonography diagnosed 41renal malignant lesions,8 renal benign lesions,35 bladder malignant lesions and 4 bladder benign lesions.While pathology showed 38 renal malignant lesions,11 renal benign lesions,34 bladder malignant lesions,5 bladder benign lesions.The sensitivity,specificity,and accuracy of contrast-enhanced ultrasonography in the diagnosis of renal bladder occupied lesions with were 94.7%,75.0%,95.4%,respectively.Conclusion Contrast-enhanced ultrasound is important in differential diagnosis of the renal and bladder occupied lesions.
