摘　　要：目的　探讨经直肠彩色多普勒超声对前列腺癌的早期诊断价值。方法　应用经腹壁及经直肠彩色多普勒超声对 32例前列腺癌患者的前列腺检查结果进行对比观察。结果　经直肠超声较经腹壁超声对前列腺癌的诊断更具敏感性 ,二者对该病的检出率具有显著性差异 (P <0 .0 5 )。应用能量图方法可较彩超更清晰显示前列腺内异常病变区血流。且血流阻力指数 (RI)明显增高。结论　经直肠彩色多普勒超声较经腹部超声可以早期提示前列腺癌 ,对前列腺癌的诊断具有重要价值。Objective To evaluate the value of color Doppler ultrasound in diagnosing prostate carcinoma.Methods A total of 32 patients with prostate carcinoma underwent transrectal ultrasound and transabdominal ultrasound for comparison.Results Transrectal ultrasound was more sensitive to prostate carcinoma than transabdominal ultrasound.There was significant difference of diagnosis rate between them(P<0.05).On color Doppler energy,blood flow in abnormal prostatic area became clear and the resistant index(RI)was increased obviously.Conclusions Transrectal color Doppler ultrasound has important value in diagnosing prostate carcinoma.It can detect prostate carcinoma at early stage beneficial for early treatment and for improving the prognosis.
