目的 :探讨超声诊断前列腺癌的新途径。方法 :应用超声检测前列腺的形态学参数及血流参数。结果 :前列腺癌组的h %、v明显高于前列腺增生组或正常组 (P <0 0 5 ) ,PI则低于其余二组 (P <0 0 5。结论 :①外腺连续性中断 ;②h % >45 % ;③v >3 0cm3;④PI <1 5 0符合上述条件 2项或 2项以上者诊断前列腺癌符合率 92 6 %、敏感性 86 2 %、特异性 97 3 %。 Objective : To explore a new way of ultrasound diagnosis of prostate cancer. Methods: Ultrasound was used to detect the morphological parameters and blood flow parameters of the prostate. Results: The h% and v in prostate cancer group were significantly higher than those in benign prostatic hyperplasia group or normal group (P <0 05), PI was lower than that in other two groups (P <0 05. Conclusion: 1 The external gland was continuously interrupted; 2h % >45 % ; 3v >3 0cm3 ; 4PI <1 5 0 in line with the above condition 2 or more than 2 persons diagnosed with prostate cancer : 92 % , sensitivity 86 2 % , specificity 97 3 % .
