摘要
目的：分析早期周围型肺癌的ＣＴ征象特点，探讨肺癌早期诊断的临床意义以及提高早期肺癌的检出率和ＣＴ诊断的准确性。材料与方法：搜集１９８０～１９９６年６５例其中４１例为查体发现，均经手术与病理证实的ＣＴ检查资料，并进行回顾性分析。结果：本组早期肺癌ＣＴ表现较高的征象有：（１）分叶征５４例（８３％）；（２）细短毛剌和锯齿征５１例（７８４％）；（３）血管集束征４４例（６７７％）；（４）空泡征／细支气管充气征３７例（５７％）；（５）胸膜凹陷征４０例（６１５％）。有５４例（８３％）出现上述３个以上征象。结论：胸部Ｘ线查体，发现病变后进行ＣＴ扫描对周围型肺癌的早期诊断有重要作用；熟悉并掌握基本的ＣＴ征象是提高肺癌早期诊断水平的关键。
Purpose: To analyze the CT features of early peripheral pulmonary carcinoma and to address the related clinical implication and to improve the CT diagnostic accuracy. Materials and Methods: Sixty five cases of periphral pulmonary bronchogenic carcinoma in early stage proved by operation and pathology were studied retrospectively. Results: 1. Basic CT manifestations were fallows:(1) lobulated sign 83% (54/65);(2)Spiculation sign 78.4% (51/65);(3)Vacuole or /and bronchiologram sign 57% (37/65);(4)blood vesseles concentrating to the lession 67.7% (44/65); (5)pleural retraction 61.5%(40/65);2. 53 cases had more than three basic signs mentioned above (83%). conclusion: well familiar and understanding the basic CT manifastations of the early peripheral pulmonary carcinoma is a key of corret diagnosis.
