周围型肺癌的X线与CT诊断临床价值对比研究。

Peripheral lung X-ray and CT comparative study of clinical value

目的：探讨对周围型肺癌患者应用X线与CT进行诊断的临床价值。方法：对我院2007年1月～2011年1月收治的40例周围型患者的X线平片和CT检查的影像学资料进行总结分析。结果：X线检查所见早期局限性小斑片阴影，增大后为圆形或类圆形，密度增高，边缘清楚呈分叶状，有印迹或毛刺，肺门淋巴结肿大；癌性空洞；胸腔积液、肋骨破坏。CT检查见早期呈小结节影，较大常呈分叶状肿块；2％～4％产生空洞。直径小于2cm内可见渺小充气的细支气管影，少数内可有偏心性钙化，肿块周围可有血管集中表现，左近胸膜出现胸膜凹陷征或胸膜皱缩征。左近胸壁受侵，产生骨质毁坏，常见于肋骨，局部可出现软组织肿块。胸膜受累或产生胸膜转移时，出现胸腔积液。晚期产生肺门，纵隔淋巴结转移和／或颅脑、肝、肾上腺等远处转移。结论：CT比X线平片诊断周围型肺癌的准确性高，二者联合应用具有重要的临床价值。

Objective：To explore the surrounding lung cancer patients with X-ray and CT diagnosis of clinical value. Methods.. The hospital in January 2007 - January 2011 around 40 cases were treated patients with type X-ray and CT imaging data were analyzed. Results：X-ray examination of the limitations of small plaques seen in the shadow of the early,increased after the round or oval, higher density, the edge clearly lobulated, with imprinted or burr, hilar lymph nodes ; cancer empty, wall thickness, eccentricity, wall irregular, uneven,may have liquid surface; pleural effusion, rib damage. X-ray with eccentric holes, uneven wall. See the early CT scan showed small nodules,often has a large lobulated mass,not the edge of the rules,multiple spike-like rise,mostly soft tissue density,are not within the rules of its low-density areas; 2%to 4%of the voids,There are gas,the hole wall without rules. Less than 2cm in diameter, visible small inflatable bronchial shadow, there are a few eccentric calcification within the tumor blood vessels can be concentrated around the performance, there Sakon pleural pleural pleural indentation or crinkle symptoms, manifested as connecting the outer edge of the pleural mass between the linear shadow, its pleural side was a small triangle. Sakon chest wall invasion, resulting in bone destruction,common in the ribs, local soft tissue mass can occur. Pleural involvement or pleural metastasis produced when the pleural effusion. Late produce hilar and mediastinal lymph node metastasis and / or brain,liver,adrenal metastasis. Conclusion：CT than the X-ray diagnosis of peripheral lung cancer with high accuracy, both in combination with important clinical value.
