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 investigate the value of transrectal color Doppler ultrasound in the early diagnosis of prostate cancer. Methods The results of prostate biopsy in 32 cases of prostate cancer were compared by transabdominal and transrectal color Doppler ultrasound. Results Transrectal ultrasound was more sensitive to the diagnosis of prostate cancer than abdominal ultrasound, the detection rate of the two was significantly different (P <0.05). Application of energy map method can be more clear than the color Doppler ultrasound shows abnormal blood flow within the prostate. And blood flow resistance index (RI) was significantly higher. Conclusion Transrectal color Doppler ultrasound can be used to diagnose prostate cancer early by transabdominal ultrasonography, which is of great value to the diagnosis of prostate cancer.
