Abstract:
Objective To investigate the value of CEUS in differential diagnosis of benign and malignant renal focal hyperechoic lesions.Methods Data of conventional ultrasound (US) and CEUS of 56 patients with single renal focal hyperechoic lesion were retrospectively analyzed,and differential diagnosis of benign and malignant lesions was performed with US and CEUS,respectively.Taking pathological diagnosis as golden standard,the diagnostic efficacy of US and CEUS were calculated and compared.Results The sensibility,specificity,positive predictive value (PPV),negative predictive value (NPV) and accuracy of US was 70.00％ (14/20),75.00％ (27/36),60.87％ (14/23),81.82％ (27/33) and 73.21％ (41/56),while of CEUS was 80.00％ (16/20),94.44％ (34/36),88.89％ (16/18),89.47％ (34/38) and 89.29 ％ (50/56),respectively.The accuracy,specificity and PPV of CEUS were higher than those of US (all P＜0.05).The consistency of CEUS and pathology was good (Kappa=0.761),while of US and pathology was ordinary (Kappa=0.435).Conclusion CEUS can improve differential diagnostic efficacy of renal focal hyperechoic lesions.
