【摘要】 超声观察３５例中心型肺癌（Ａ组）及２６例其他原因（Ｂ组）所致无气肺内结构。发现支气管扩张、充满液体的＂液相＂在两组有明显的差异（Ｐ＜０．０１）。Ａ组的液相显示率为７７％（２７／３５例）．呈显著扩张；Ｂ组的显示率为１５％（４／２６）．呈轻度扩张；支气管＂液相＂对中心型肺癌的诊断准确率可达８０％（４９／６１例）．为不可忽视的重要指征。本文１９例经彩超及脉冲多普勒检查．其中１４例确认无气肺内扩张的管道为肺动脉．该方法是判断管道性质简易而有效的手段。更多还原

【Abstract】 Abstract patients with air-space consolidations or atelectases of the lung,which were caused by central lung cancers(CLC,n=35)and other diseases(OD,n=26),were studied with ultrasound.In the abnormal area of the lung,the bronchial fluid phase which presented with a dilated tube filled with some fluid was found between CLC and OD(77%vs 15%,P<0.01),with an accuracy being 80%(49/61).In 14 of the 19 cases performed with duplex ultrasound and color doppler flow imaging,tubular structures imaged were proved to be pulmonary arteries or their branches.Conseguently,our Study shows that the bronchial fluid phase on a monographic image may predict the existence of central carcinoma of the lung and the doppler assessment is a simple and practical method of the distinction between the bronchus and the artery.更多还原
