摘　　要：目的分析超声造影、MSCT三期增强检查对肾癌的诊断价值。方法回顾性分析我院2017年6月至2019年7月收治的84例肾癌的临床资料,比较超声造影检查和MSCT检查对不同病理分级肾癌诊断准确率。结果94例患者经超声造影检诊断准确率为95.24%,MSCT检查诊断准确率为92.86%(P>0.05);两者联合检查的诊断准确率为98.81%。84例患者超声造影检查显示实性肿块51例,其中周边有环状无回声20例;囊性肿块33例;低回声21例,等回声19例,高回声44例;造影增强后,可见高回声28例,等回声35例,低回声21例。43例肿瘤周围可见假包膜,21例肿瘤内部显示部分不增强,20例造影后显示"蜂窝状"结构。MSCT检查显示4例患者表现为高密度,低密度49例,等密度31例。19例患者肿块呈圆形,12例呈椭圆形,30例呈类圆形,不规则形者23例。结论MSCT检查和超声造影检查均可有效显示肾癌的影像学特点,但是两者联合检查诊断准确率更高,可为临床上诊断肾癌分级提供可靠的依据。Objective To analyze the diagnostic value of contrast-enhanced ultrasonography and MSCT threephase enhanced examination for renal carcinoma.Methods The clinical data of 84 cases with renal carcinoma admitted from June 2017 to July 2019 in our hospital were retrospectively analyzed.The diagnostic accuracy of contrast-enhanced ultrasound and MSCT for of renal carcinoma in different pathological grades was compa red.Results The diagnostic accuracy of cont rast-enhanced ultrasound for 94 patients was 95.24%,and the diagnostic accuracy of MSCT was 92.86%(P>0.05).The diagnostic accu racy of the combined exa mination was 98.81%.In this group with 84 patients,contrast-enhanced ultrasonography showed 51 cases with solid mass,including 20 cases with ring-like no-echo in the periphery,33 cases with cystic mass,21 cases with hypoecho,19 cases with isoecho,44 cases with hyperecho.After contrast enhancement,there were 21 cases with hypoecho,35 cases with isoecho,28 cases with hyperecho.pseudo-envelope was seen around tumors in 43 cases,and in 21 patients,the internal part of the tumor showed no enhancement in part.20 cases after angiogra phy showed a "honeycomb" structu re.MSCT exa mination showed high density in 4 patients,low density in 49 cases,and equal density in 31 cases.The mass of 19 patients were round,the mass of 12 patients were oval,the mass of 30 patients were round,and the lumps of 23 patients were irregular.Conclusion MSCT examination and contrast-enhanced ultrasonography can effectively display the imaging features of renal cancer,but the combined diagnosis of them is more accurate,which can provide reliable basis for clinical diagnosis of renal cancer in clinic.
