Abstract Objective: To discuss the diagnostic value of superb microvascular imaging(SMI) in bladder occupied lesions. Methods: Forty-four bladder occupied lesions in 32 cases founded by conventional ultrasound were analyzed retrospectively. All the lesions were examined by color Doppler flow imaging(CDFI), power Doppler(PD), advanced dynamic flow(ADF) and SMI respectively. The differences between these 4 blood flow display technologies in displaying blood flow and basal perforator vessels in bladder occupied lesions were compared with surgical pathological results. Results: There were 39 bladder cancers and 5 glandular cystitis lesions in 44 lesions of 32 cases. The blood flow display rate of SMI in diagnosing bladder occupied lesions was 100%, which was obviously higher than CDFI(77.3%), PD(81.8%), ADF(84.1%). The basal perforator vessels display rate of SMI was 84.1%, which was also obviously higher than CDFI(43.2%), PD(47.7%), ADF(56.8%). All these results had significant statistical differences(P<0.001). Conclusions: SMI can increase the display rates of blood flow and basal perforator vessels of bladder occupied lesions and it has high diagnostic value in differential diagnosis of benign and malignant bladder occupied lesions.
