Abstract: Objective To detect the impact of ultrasound elastography in diagnosis of prostatic cancer,and to evaluate its capability in differentiating benign from malignant lesions.Methods From June 2013 to February 2015, we selected 50 patients with different prostatic lesions,and suspicious for malignancy were included.All patients had a conventional B-mode ultrasound examination and color Doppler imaging,and then real time ultrasound elastography was performed in the same session.Finally,the results were compared to the histopathological results of those lesions. Results The addition of Strain ratio parameter for evaluating the elastography images showed the highest sensitivity of 74.2%,specificity of 73.7% and accuracy of 74.0% at a best cut off point of 5.5 between benign and malignant lesions.Conclusion Prostate US combined with elastography can be a helpful tool for guiding malignant lesions.Also it can help in targeting the biopsy site.
