Abstract: ［Abstract］ Objective〖HTSS〗〓To classify the relationship between the subsolid nodules(SSNs) and the bronchi and the surrounding vessels in different pathological types, and to investigate the diagnostic value of benign and malignant nodules.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Multislice spiral CT imaging of 101 subsolid nodules were retrospectively reviewed. According to the relationships between bronchus and the component of subsolid nodules, the types between subsolid nodules and bronchi were divided into five types. Depending on the vasculars' expansion or not and their tracks, the types between subsolid nodules and vasculars were categorized into four types. Statistical analysis was performed on the relationship between the types of vascular and brochi and subsolid nodules.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Of 47 benign subsolide nodules, brochus type Ⅴ and Ⅳ(27/47, 17/47) were the main relationships and the vascular type Ⅱ and Ⅲ(28/47,13/47) were the main relationships. Of 39 invasive adenocarcinomas, brochus type Ⅰ(21/39) was the main relationship and the vascular type Ⅲ and Ⅳ(23/39,12/39) were the main relationships. All of the nodules of premalignant group, microinvasive adenocarcinoma group and invasive adenocarcinoma group were not the brochus type Ⅴ and all of the nodules of microinvasive adenocarcinoma group and invasive adenocarcinoma group were not the vascular typeⅠ. There was significant statistic significance between the different pathology patterns of subsolid nodules and the lesion sizes, the types of brochi and vascular（P＜0.01）.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Different types of bronchi and vascular predict different pathology patterns of subsolid nodules. It is important to predict the malignant and benign of subsolid nodules.
