Abstract Objective: To evaluate the effect and significance of shear wave elastography(SWE) in improving the detection rate of prostate cancer. Methods: Seventy-six cases of clinically suspected prostate cancer patients included. System 10-point puncture plus SWE exception handling puncture were used, discuss the role of SWE in improving the detection rate of prostate cancer by comparing the results of puncture. Results: Seventy-six cases of suspected prostate cancer patients were successfully punctured. The pathologically confirmed prostate cancer in 32 cases, benign lesions in 44 cases. 10-point system was positive in 25 cases, about 32.89% and SWE puncture positive anomaly at 28 cases, about 36.84%． The number of 10-point system were 760 and the number of positive were 84, the single needle positive rate was 11.05%． The number of SWE were 112 and the number of positive were 76, the single needle positive rate was 67.86%, significantly higher than 10-point system(P<0.05)． The sensitivity of SWE for detection of 76 patients with suspected prostate cancer was 87.50%, specificity 86.36%, accuracy 86.84%, the positive predictive value 82.35%, the negative predictive value 90.48%. Conclusions: SWE can help identify targets for biopsies and improve the detection rate of prostate cancer.
