早期周围型肺癌的X线与CT诊断分析

The X-ray and CT Diagnosis of Early Peripheral Pulmonary Carcinoma

目的:分析早期周围型肺癌的X线与CT征像特点,探讨X线与CT检查在早期周围型肺癌诊断中的作用。方法:对65例直径<3cm,经手术病理证实的周围型肺癌的X线胸片及CT扫描征象进行回顾性分析。对两种检查方法的定性准确率进行统计学检验。结果:分叶征、毛刺征、空气支气管征、血管集束征及胸膜凹陷征为早期周围型肺癌的基本征象。对病灶的定性诊断CT扫描明显优于普通X线检查(x=5.47 P<0.025)。结论:胸部X线检查是发现病变的基本首选方法,发现病变后进行CT扫描对早期周围型肺癌的确诊有重要意义,熟悉并掌握早期周围型肺癌的基本X线及CT征象是提高肺癌早期诊断水平的关键。

Objective: To analyze the X-ray and the CT features of early peripheral pulmonary carcinoma and to evaluate the effect of the X-ray and the CT in the diagnosis of peripheral pulmonary carcinoma. Methods: The X-ray and the CT features of sixty five cases with early peripheral pulmonary carcinoma(d < 3cm) proved by operation and pathology were studied retrospectively, and analyze statistically the accuracy of the two imaging methods. Results: The basic manifestations of CT in the 65 cases were as fallows: lobulated sign; spiculation sign; bronchiologranl sigh; blood vessels concentraling to the lesion and pleural retraction. The accuracy of the CT diagnosis was better than the X-ray diagnosis. Conclusion: The CT scan should be choiced once the X-ray check found solitary pulmonary nodule. Master the basic CT manifestations of the early peripheral pulmonary carcinoma play an important role in the correct diagnosis.
