摘  要:目的 探讨超声造影定性及定量技术在鉴别肾脏良恶性肿瘤中的应用价值。方法 选择2017年1月至2019年3月经手术病理证实的肾脏实质性占位患者59例作为研究对象,术前均行超声造影检查,比较分析肾脏良恶性肿瘤超声造影定性及定量参数之间的差异。结果 47例为肾脏恶性肿瘤(42例透明细胞癌,3例嫌色细胞癌,2例乳头状细胞癌),12例为肾脏良性肿瘤,均为血管平滑肌脂肪瘤。定性指标方面:达峰不均匀增强在肾恶性肿瘤中明显高于肾良性肿瘤(44.68% vs 8.33%,P=0.022);定量指标方面:肾脏恶性肿瘤上升时间和达峰时间显著低于肾脏良性肿瘤,而肾脏恶性肿瘤的峰值强度明显高于肾良性肿瘤(P<0.05,P<0.01)。结论 超声造影定性及定量技术对于鉴别肾脏良恶性肿瘤有较高的临床应用价值。Objective To investigate the application value of qualitative and quantitative contrast-enhanced ultrasound in differentiating benign and malignant renal tumors.Methods A total of 59 patients with renal parenchymal space occupying confirmed by surgery and pathology from January 2017 to March 2019 were selected as the research objects.All patients underwent contrast-enhanced ultrasound(CEUS)before operation.The differences between qualitative and quantitative parameters of CEUS were compared and analyzed,and the value of CEUS in differentiating benign and malignant renal lesions was discussed.Results There were 47 cases of renal malignant tumors(42 cases of clear cell carcinoma,3 cases of chromophobe cell carcinoma,2 cases of papillary cell carcinoma),12 cases of benign renal tumors,all of them were angiomyolipoma.The peak uneven enhancement was significantly higher in renal malignant tumors than in benign renal tumors(44.68%vs 8.33%,P=0.022).The rise time and time to peak of renal malignant tumor were significantly lower than those of benign renal tumor,while the peak intensity(IMAX)of renal malignant tumor was significantly higher than that of renal benign tumor(P<0.05,P<0.01).Conclusion The qualitative and quantitative techniques of contrastenhanced ultrasound have high clinical application value in differentiating benign and malignant renal tumors.
