Abstract：Objective:To investigate the clinical value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of prostate cancer in patients with different concentrations of prostate-specific antigen (PSA).Methods:Based on the PSA concentration,186 patients were divided into three groups (PSA 4-10 μg/L,11-20 μg/L,and ＞ 20 μg/L) and underwent transrectal CEUS and biopsy.We compared the pathological results with the CEUS features in different groups of patients and performed a statistical analysis on the characteristics of the CEUS manifestations of prostate cancer and benign prostatic lesions.Results:Of the 186 patients,118 (63.4％) were diagnosed by biopsy with prostate cancer and the other 68 (36.6％) with benign prostatic lesions.The positive rate of CEUS in the diagnosis of prostate cancer was above 95％ in all the three groups,significantly higher than that of conventional ultrasound in the PSA 4-10 and ＞ 10-20 μg/L groups (P ＜ 0.01).Conclusion:Contrast-enhanced ultrasonography can achieve a high detection rate in the diagnosis of prostate cancer,especially for the patients with a low PSA concentration,and therefore can be used as one of the most valuable diagnostic techniques for this purpose.
