The application of contrast-enhanced ultrasound in the diagnosis of renal and bladder occupied lesions

Purpose To explore the value of ultrasound contrast agent SonoVue and Cadence Pulse sequencing(CPS)in diagnosing renal and bladder occupied lesions.Methods Conventional and contrast-enhanced ultrasound were performed on 88 suspected renal and bladder occupied lesions.The results were compared with that of pathology.Results Contrast-enhanced ultrasonography diagnosed 41renal malignant lesions,8 renal benign lesions,35 bladder malignant lesions and 4 bladder benign lesions.While pathology showed 38 renal malignant lesions,11 renal benign lesions,34 bladder malignant lesions,5 bladder benign lesions.The sensitivity,specificity,and accuracy of contrast-enhanced ultrasonography in the diagnosis of renal bladder occupied lesions with were 94.7%,75.0%,95.4%,respectively.Conclusion Contrast-enhanced ultrasound is important in differential diagnosis of the renal and bladder occupied lesions.
