When observing the perfusion mode of the mass, we analyzed the perfusion characteristics of contrast-enhanced ultrasound and compared them with the surgical pathological results.Results: Sixty-seven lesions, which were identified in 67 patients with renal space-occupying lesions, included 55 renal malignant tumors and 12 benign ones. The sensitivity of qualitative diagnosis by CEUS imaging was 96.4%, the specificity was 66.7%, and the accuracy was 91.0%.Conclusion: The real-time blood supply of renal space-occupying lesions helps judge their nature according to the enhancement mode. It has high clinical application value in diagnosing benign and malignant lesions.Keywords: ultrasound examination, renal lesions, contrast-enhanced ultrasound
