Abstract:
Objective： The current study was designed to assess the clinical value of heteromorphic enhanced vessel sign in the thin section CT images in diagnosis and distinguished diagnosis for small lung cancer. Methods： A total of 37 distinguished small peripheral lung cancer with less than 3 cm diameter were compared between enhanced thin section CT and conventional enhanced CT. At the same time,18 pulmonary inflammatory pseudotumors and pulmonary tuberculomas required distinguished have been studied as control. The enhanced thin section CT images of the three kinds of diseases were investigated. Results： 1.The enhanced thin section CT scan apparently showed the special signs (heteromorphic enhanced vessel signs) of the tumor vessel in small lung cancer, which was rarely displayed on conventional CT images. 2.The heteromorphic enhanced vessel sign was rarely found in pulmonary inflammatory pseudotumor and pulmonary tuberculoma. Conclusion： The heteromorphic enhanced vessel sign is a valuable CT characteristic for diagnosis and distinguishing diagnosis for small lung carcinoma.
