ABSTRACT
Objective To compare the difference of colour Doppler flow imaging(CDFI)and superb-microvascular imaging(SMI)for detecting blood flow in cystic renal mass,and explore the consistency of conventional ultrasound combined with SMI and Contrast-enhanced ultrasonography(CEUS) in the diagnosis of renal cystic masses based on the Bosniak classification system,so as to evaluate the diagnosis value of SMI in renal cystic masses.Methods Fifty-five patients with renal cystic mass were enrolled in this study and underwent conventional ultrasound,CDFI and SMI.Patients with renal cystic mass at category Ⅱ for higher received contrast-enhanced ultrasonography additionally.The diagnostic performance of SMI and CEUS were evaluated based on final diagnosis obtained by follow-up or pathology diagnosis after surgery.Results In 55 cases,44 cases got the pathological diagnosis afer surgical resection including 38 cases of malignant masses,and 6 cases of benign masses.CDFI and SMI showed significant difference in tumor flow imaging(P <0.05).Kappa Value of SMI and CEUS was 0.866.The sensitivity,specificity, accuracy,positive predictive value and negative predictive value of SMI were 94.8%,75.0%,89.1%,90.2% and 85.7% respectively.Conclusions SMI is superior to CDFI in displaying micro-vascular of separated and solid structure in renal cystic masses.SMI has a better consistency with CEUS in Bosniak classification.SMI can improve the accuracy of non-invasive ultrasound in the diagnosis of renal cystic lesions.
