摘　　要：目的 :探讨增生前列腺内腺低回声前列腺癌与低回声增生结节在声像图及血流动力学方面的差异 ,提高前列腺癌的早期诊断水平。方法 :经直肠彩色多普勒超声对增生前列腺内腺 31个低回声增生结节及 18个低回声前列腺癌的形态、边界、动脉收缩期最大血流速度 (Vs)、阻力指数 (RI)及搏动指数 (PI)进行对比性分析。结果 :前列腺癌相对增生结节来说 ,边界不甚清楚 ,形状不规则 ,Vs、RI、及PI均明显增大 (P <0 0 1)。结论 :增生前列腺内腺低回声的增生结节与前列腺癌声像图表现及Vs、RI。Objective:To observe the sonographic appearance and hemodynamic features of hypoechoic hyperplastic lesions and hypoechoic cancer lesions in the hyperplastic prostate inner gland to raise the early accuracy rate for prostate cancer.Methods:Thirty one cases with hypoechoic hyperplastic lesions and 18 cases with hypoechoic cancer lesions in the hyperplastic prostate inner gland were observed Comparative analysis of their shape、edge and Vs RI PI was introduced.Results:As compared with the hyperplastic group,in the cancergroup the lesions revealed the shapes more irragular and the rims more unclear and the Vs,RI,PI were highter than those in the hyperplastic group.Conclusions:The sonographic appearance and Vs RI PI have important value in distinguishing hypoechoic hyperplastic lesions and hypoechoic cancer lesions in the hyperplastic prostate inner gland.
