肺癌的胸片体层片与CT、BAG的X线表现和诊断价值比较

目的：探讨胸片，体层片和CT，支气管动脉造影（BAG）对肺癌的诊断价值并对其进行比较，方法：对照病理检查结果对101例患者的胸片、体层片和CT、BAG的X线表现和诊断价值进行回顾性分析，结果：61例肺癌、胸片、体层片诊断正确43例（70．5％）；定性困难16例（26．2％）；误诊8例（13．1％（）。CT诊断正确57例（93．4％）；误诊4例（6．6％；40例肺癌：BAG中有肿瘤血管改变者35例（87．5％）。特征性造影表现有肿瘤血管（27例、67．5％）；肿瘤染色（20例、50％）；肿瘤包烧（835例、87．5％）。结论：胸片，体层片和CT对肺癌具有很高的诊断价值。以CT为优，胸片，体层片显示段以上支气管情况和肿块整体形态较好，CT显示肿瘤的内部结构，轮廓、瘤周、纵隔胸膜转移和纵隔旁及脊柱旁区病灶具有明显优势。BAG对肺癌有一定的诊断价值。

Radiological Manifestation and Diagnostic Significance Comparison of Conventional X-ray Film. Tomographic Film and CT, BAG in Pulmonary Carcinoma

Purpose: To evaluate and compare the diagnostic Value of conventional X-ray film, tomographic film and CT, BAG (bronchial arteriography) in pulmonary carcinoma. Methods: With pathologic correlation authors retrospectively analyzed the radiological manifestation of chest rediograph,tomographic film and CT, BAG of 101 cases in pulmonary carcinoma. Rusults: chest radiogram, tomographic film and CT had been performed in 61 cases, correct diagnoses, undefinite diagnoses, missed diagnoses were made on the basis of chest radiogram, tomographic film in 43 cases(70.5%), 16 cases (26.2%),8 cases (13.1%). Correct diagnoses and missed diagnoses were made by CT in 57 cases (93.4%) and 4 cases (6.6%). BAG had been performed in 40 cases. the typical theriographic manifestation of carcinoma was tumor vessel,tumor stain tumor encirclement it were described 27 cases(67.5%); 20 cases (50%); 35 cases (87.5%). The rate of successful aniography carcinoma could be identibied accurately by chest radiogram, tomoglaphic film and CT, CT is more sensitve in demonstrating bronchus in pulmonary segment and pulmonary lobe and appearances of entire tumor. Compared with plain chest film, tomographic film. CT is more sensitive in demonstrating internal structural of lesion, margin, peritumoral, metastases in mediastinum and pleura, lesions in perimediastinum and perispine. BAG is helpful to the correct diagnosis of pulmonary carcinoma.
