细支气管肺泡癌的薄层CT诊断(附65例报告)

Thin section CT Diagnosis of Bronchioloalveolar Carcinoma

目的：探讨细支气管肺泡癌在簿层ＣＴ上的表现与意义。资料与方法：搜集１９９４年１２月至１９９６年１２月经薄层ＣＴ扫描和病理证实的６５例细支气管肺泡癌。扫描方法：先以１０ｍｍ层厚，１２５ｋＶｐ，２５０ｍＡｓ，自肺尖到肺底逐层扫描，然后对病变区行１～１．５ｍｍ层厚薄层扫描并放大。结果：６５例细支气管肺泡癌的ＣＴ表现可分为五型：（１）孤立结节型，（２）肿块型，（３）斑片型，（４）弥漫型，（５）混合型。结论：薄层ＣＴ扫描对细支气管肺泡癌的诊断很有价值。

Purpose:To evaluate the features and signifivance of bronchioloalveolar carcinoma(BAC) on the thin section CT.Meterials and methods:From December 1994 to December 1996,65 case of BAC were examined at the thin section CT.CT scans were performed with 10 millimeter thick section,125 kVp,250mAs,from the apexes to lung bases,then the targed areas were scaned with 1.5 to 20 millimeter section,125kVp,250mAs.Reasults:of 65 cases of BAC,CT images displayed 5 patterns:solitary,patch,mass,diffuse and mixed types.Conclusion:It is great value to the diagnosis of BAC with thin section CT.
