摘　　要：目的探讨经直肠前列腺超声造影在前列腺癌穿刺活检术中的应用价值。方法分析我科行经直肠超声引导前列腺穿刺活检术的487例可疑前列腺癌患者的临床资料,其中研究组85例患者,采用SonoVue造影剂及对比脉冲序列造影成像技术在前列腺穿刺活检前进行经直肠前列腺超声造影;对照组402例患者,直接进行经直肠超声引导前列腺穿刺活检,对比两组患者前列腺癌穿刺活检的阳性率。结果研究组前列腺癌结节超声造影表现为早期高增强,早消退。前列腺癌穿刺活检阳性率为43.53%,明显高于对照组28.11%(P<0.05);而两组在穿刺活检针数及并发症发生率差异无统计学意义(P>0.05)。结论在不增加穿刺活检针数的情况下,经直肠前列腺超声造影能提高前列腺癌的穿刺活检率,具有推广应用价值。Objective To explore the application value of transrectal contrast - enhanced ultrasound（CEUS） in biopsy of prostate cancer. Methods The clinical data of 487 patients with suspected prostate cancer were anaiyzed. In study group, CEUS was performed on 85 patients with SonoVue and CPS before prostate biopsy, while in control group, prostate biopsy was performed on 402 patients without CEUS. Then the positive rate was compared between the two groups. Results The CEUS appearance of prostate cancer nodules in study group were high enhancement and early regression in early phase. The positive rate of prostate cancer biopsy in study group and control group was 43.53% and 28.11% ,respectively （P 〈0.05 ）. There was no significant difference of the amount of biopsy and the complication incidence rate between the two groups （ P 〉 0.05 ）. Conclusion CEUS can improve the biopsy rate of prostate cancer, it is worth spreading to use in clinic.
