超声形态学及血流测定诊断前列腺癌的初探

Preliminary studies in diagnosing prostatic cancer by ultrasound morphology and blood flow

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 %。

Purpose:To study the new means of diagnosing prostatic cancer with ultrasound. Methods:To use ultrasound determining the morphology parameter and the PI of the follow three groups: the prostaticcancer group, the prostate hyperpophy group and the normalcontrust group. Results:The ‘h%’ and the ‘V’ in the prostatc cancer group is higher than them inthe prostate hyperpophy group or the normal contrust group ( P <0 05), and the PI in the prostatic cancer group is smaller than one in the prostat hyperpophy group or the normal contrust group ( P <0 05). Conclusions:①The continuity of prostatic outside gland was broken off,②the h%>45?%,③the V>3 0?cm 3, ④the PI>1 30, when or more than 2 of aforementioned condition one was conelated to the diagnosis rate for prostatic cancer at 92.6%, the sensitirily was 86.2%, the specficily was 97.3%.
