摘要 目的 了解彩色多谱勒血流显像在诊断前列腺癌中的价值。 方法 对80例疑诊前列腺癌的患者，进行前列腺低回声区的血流显像检测和前列腺结节组织穿刺活检。 结果 全组血流显像率为68%(54/80)。血流显像的54例中63%(34/54)为前列腺癌，前列腺增生占37%(20/54)。经卡方检验两组的血流显像率差异有极显著性意义(χ² =15.93，P=0.0001)。血流显像的灵敏度为0.89，特异度0.52，阳性预测值为0.63。 结论 前列腺结节的血流显像与前列腺癌有一定关系。直肠B超探测前列腺结节时应加作结节的超声血流显像。

Abstract Objective To investigate therole of color doppler flow imaging in diagnosis of prostate cancer. Methods Transrectalultrasound and color doppler flow imaging were conducted for 80 patients suspected ofprostate cancer. All the patients underwent prostate biopsy. Results Among the 80patients,42 were BPH (53%) and 38 were prostate cancer (47%). The total positive frequencyof color doppler flow imaging was 68% (54/80).Of the 54 color doppler flow imagingpositive cases 34 were malignant and 20 benign(χ² =15.93 ......
