摘　　要：目的对肾癌和肾血管平滑肌脂肪瘤(AML)行超声造影(CEUS)和增强CT(CECT)鉴别诊断,分析其影像学特征及临床价值。方法回顾性分析医院2020年3月-2022年3月收治的27例肾癌患者与21例AML患者临床资料,对所有患者CEUS与CECT检查的诊断结果及影像学资料进行整理,分析两种检查方式与联合检查对疾病诊断情况,分析不同疾病呈现的影像学表现,比较诊断准确率。结果肾癌组和AML组中CEUS与CECT癌灶增强程度、增强均匀度及假包膜征方面,两组间比较差异均无显著性(P>0.05);在肾癌、AML诊断准确率方面,CEUS联合CECT检查均优于CEUS单独检查、CECT单独检查,差异均有显著性(P<0.05);对CEUS、CECT和两者联合的诊断评分进行ROC分析,AUC均大于0.8,与CEUS检测、CECT检测相比,两者联合检测AUC显著提高(P<0.05)。结论CEUS检查和CECT检查均可有效显示肾癌和AML影像学特点,但两者所表现的病灶特征侧重存在差异,其中联合检测诊断准确率更高,在检测肾肿瘤扩散程度、增强模式方面更准确,使诊断效能有效提高。Objective To carry out the differential diagnosis of renal carcinoma and renal angiomyolipoma(AML)byCEUS and CECT,and to analyze their imaging features and clinical value.Methods The clinical data of 27 renal cancer patients and 21 AML patients admitted to the hospital from March 2020 to March 2022 were selected for retrospective analysis,and the diagnostic results and imaging data of CEUS and CECT examinations of all patients were sorted out.The diagnosis of the disease by the two examination methods and the combined examination was analyzed,the imaging manifestations of different diseases were analyzed,and the diagnostic accuracy was compared.Results In the enhancement degree,there was no significant difference between the two groups,enhancement uniformity and pseudocapsule sign of CEUS and CECT in the renal cancer group and the AML group(P>0.05).In terms of CEUS combined with CECT,both CEUS and CECT were superior to CEUS alone and CECT alone(P<0.05).The AUC value of the combination of items was the largest,has a statistically significant compared with the two separate tests(P<0.05).Conclusion Both CEUS and CECT can effectively display the imaging features of renal cancer and AML,but there are differences in the focus of the lesions.Compared with the two alone,the combined detection has a higher diagnostic rate.The extent and enhancement pattern of renal tumors are more accurate,which can effectively improve the diagnostic efficiency.
