本文对病理证实的周围型小肺癌３２例的瘤—肺界面进行了ＨＲＣＴ与病理的前瞻性对照研究。术前有ＨＲＣＴ扫描，术后标本充气后ＨＲＣＴ扫描，然后行Ｈｅｉｔｓｍａｎ法固定４８－７２，小时，标本制成组织学切片。对照观察术前．术后标本ＨＲＣＴ及组织学切片，结果表明ＨＲＣＴ能精确反映瘤—肺界面的大体病理改变。周围型小肺癌ＨＲＣＴ常表现为（１）分叶，（２）毛刺，（３）边缘模糊或部分边缘模糊，（４）纵隔窗上边缘锐利。作者初步认为ＨＲＣＴ对周围型小肺癌定性诊断十分重要。
This article prospectively studied HRCT and pathology of the tumor-lung interface in 32 cases of peripheral small lung cancer confirmed pathologically. Preoperatively, HRCT scans were carried out. After the specimens were inflated, they were scanned by HRCT, then fixed by Heitsman method for 48-72 hours, and the specimens were made into histological sections. Control observation before surgery. The HRCT and histological sections of the postoperative specimens showed that HRCT can accurately reflect the gross pathological changes of the tumor-lung interface. The peripheral HRCT of small lung cancer usually manifests as (1) lobar, (2) burrs, (3) blurred edges or partial edge blurring, and (4) sharp edges on the mediastinal window. The authors initially believe that HRCT is very important for the qualitative diagnosis of small peripheral lung cancer.
