摘要
目的分析超声造影鉴别诊断肾脏占位性病变的临床价值。方法选取2014年10月至2016年12月76例病例,回顾分析术前的超声造影特征。结果超声造影诊断肾脏占位性病变的准确性为92.1%,特异度90.3%,灵敏度为93.3%。46例恶性占位患者中,37例为实性占位,9例为囊实性占位;30例良性占位患者中,实性占位18例,囊性占位12例。恶性病变患者的动脉血流显示率和血流显示率为91.3%和95.7%,高于良性病变患者的73.3%和76.7%(P<0.05);两者RI和Vmax的比较无统计学差异(P>0.05)。良、恶性病变患者血流信号分级情况的对比具有统计学差异(P<0.05)。结论超声造影对肾脏占位性病变的诊断及鉴别诊断具有重要的临床意义。
Objective To explore the clinical value of ultrasonic imaging in the diagnosis and differential diagnosis of renal space-occupying lesions. Methods The preoperative imaging characteristics of 76 confirmed cases of renal space-occupying lesions treated during Oct. 2014 and Dec. 2016 were retrospectively analyzed. Results The accuracy of contrast-enhanced ultrasound was 92.1%, the specificity was 90.3%, and the sensitivity was 93.3%. In 46 malignant cases, 37 were solid lesions, and 9 were cystic. Of the 30 benign cases, 18 were solid lesions and 12 were cystic. The detection rates of arterial blood flow and blood flow display in malignant cases were 91.3% and 95.7%, higher than those in the benign cases（73.3% and 76.7%, P〈0.05）. There was no statistical difference in RI and Vmax（P〉0.05）. There was statistical difference in blood flow signal classification between benign and malignant cases（P〈0.05）. Conclusions Contrast-enhanced ultrasound is clinically significant for the diagnosis and differential diagnosis of renal space-occupying lesions.
