摘要
目的 :探讨肺内球形灶血管支气管平行CT征的病理基础及诊断价值。方法 :选择 1 2例肺内球形灶血管支气管平行CT征进行病理对照研究。所有病灶大小为 3 .0～ 6 .0cm。机型为ElscientCTTwin和GEProspeedCT机 ,1 2例均经肝静脉注射对比剂后 ,从肺尖至肺底扫描 ,层厚 1 0 .0mm ,依病灶大小 ,加扫薄层 3 .0～ 5 .0mm ,手术标本按Heitzman法制标本。根据CT横断面扫描特点 ,将标本病灶部分进行横断 ,作 0 .5～ 1 .0cm厚组织切片 ,然后 ,对“兴趣区”取材作石腊切片 ,HE染色 ,光镜观察 ,进行病理对照。结果 :在 1 2例肺球形灶血管支气管平行CT征中 ,除 1例肺炎性假瘤外 ,其余均为肺恶性肿瘤。结论
Objective:To explore the pathological basis and the diagnostic value of the bronchovascular parallar CT sign of pulmonary spherical foci.Methods:A comparative study of the bronchovascular parallar CT sign of the lung with the pathological examination was done in 12 cases.All foci were 3～6cm in diameter.The scanner were Elscient CT Twin and GE prospeed.All the scans were performed at 10mm intervals from the tips to the base of lung after intravenous injection of contrast materials.Additionally the thin slice with 3～5mm were done acoording to the size of foci.The pathological specimens were fixed in acoodance with Heitzmen method and sectioned transversely at 0.5～1.0cm intervals in same plane at the CT scan.The microscopic examination of the region of interest was performed for comparison with the CT sign.Results:All but 1 inflammatory pseudotumor were proved as malignant lung tumer in 12 bronchovascular parallar CT sign of the pulmonary spherical foci.Conclusion:The bronchovascular paralla,CT sign is valuable in the diagnosis of malignant lung tumor.
