摘　　要：目的 :探讨彩色多普勒对肺部良恶性肿块诊断的价值。　 方法 :采用彩色多谱勒 ,探头频率 3.5～ 5MHz,取样容积 2～ 3mm,滤波频率为 50 MHz,校正角度 <60度 ,检查 54例肺部肿块 ,均经穿刺活检证实。　 结果 :34例恶性肿块有 30例 ( 88.2 4 % )均能在内部或边缘测得点状、短条状的高阻力动脉血流信号 ,RI指数在 0 .668～ 1.0 0 ;余未测到血流信号。 2 0例良性肿块中 ,仅 4例 ( 2 0 % )测得点状静脉及低阻力动脉血流 ,RI指数为 0 .333～ 0 .4 88;其余 16例中 9例仅测得稀疏的静脉血流 ,7例无血流信号。　 结论 :根据本组结果动脉血流的检出率及 RI阻力指数 >0 .50 。Objectives:To study the value of color doppler ultrasound in the qualitative diagnosis of lung malignant and benign masses. Methods:Fifty- four lung masses were analysed by color doppler ultrasound with a3.5～ 5 MHz trans- ducer,while the sample volume size between 2～ 3mm,frequency of wall filter set- ting was at 5 0 MHz,correct angles were less than 6 0 degree.The diagnosis was proved by ultrasound- guided needle biopsy pathology in all patients. Results :In 30 cases of the malignancy(88.2 4% ) ,points and short strip pattern high- resistive arterial- blood flow could be detected in or around the masses,and the resistive in- dex was from 0 .6 6 8to 1 .0 0 versus 0 .333to 0 .488in benign masses.In the rest 4 cases,no flow signal was detected.Only 4cases of benign lesions(2 0 % ) had points pattern venous and low resistent arteries.Among the rest1 6 cases,venous flow was rare in9and7cases had no flow signals. Conclusions:The important indica- tion of diagnosing malignant masses in the lung was high detectable rate of arterial- blood and resistic index(>0 .5 ) .Resistive index
