| 目的 利用超声多普勒检测前列腺癌的局部血流,为前列腺癌的诊断与鉴别提供影像学依据。方法 本文通过经腹壁、会阴及直肠扫查,观察比较了16例前列腺腺癌和20例前列腺增生的超声多普勒血流及二维切面形态的改变。结果 16例前列腺癌与20例前列腺增生的前列腺大小相差不显著,两组的病变结节大小、形态及回声类型相近,前列腺癌结节可向包膜外突出;两组的彩流分布有所不同:增生组的血流信号主要见于内腺的边缘,增生结节的内部及周边稀少、呈点状,脉冲多普勒可检出低速的脉动血流频谱,Vmax为(11.5±0.8)cm/s;腺癌组的肿块周围及"结节"内部可见较丰富的血流信号、呈环状及簇状,Vmax为(24.5±10.7)cm/s,明显高于增生组(P<0.05)。部分腺癌放疗后病灶内血流信号有所减少。结论 增大的前列腺内具有较丰富、流速较高动脉血流信号的结节样病灶应高度考虑前列腺癌的可能。 |

| Objective To extend imaging data for the diagnoses of prostate carcinoma. Methods Sixteen cases of prostate carcinoma and twenty cases of prostatic hyperplasia were examined by duplex transabdominally,perineally and endorectally. Results There were no obvious differences in the size of the prostate and the echo signs of the prostatic nodes between the cases of prostate carcinoma and the cases of prostatic hyperplasia, but different distributions of the color Doppler flow imaging were observed among the cases. In the cases of prostatic hyperplasia, color Doppler signal was mainly seen at the edge of inner grand of prostate with only a little spot-like color signal in the nodes and the peak velocities (PV) were (10.5±0.8)cm/s,while in the cases of prostate carcinoma, plentiful cluster of color Doppler signal could be detected in the nodes and the PVs were (24.5±10.7)cm/s.Reduced blood flow in the patients with the tumors treated by radiotherapy were also observed. Conclusion The possibility of prostate carcinoma should be considered when a prostatic hyperplasia has the nodes with plentifully arterious signal. |
