Study on 256-slice spiral CT bronchial artery imaging of common pathological types of central-type lung cancer.

OBJECTIVE: In this study, we analyzed features of 256-slice spiral CT bronchial artery imaging in common pathological types of central-type lung cancer to provide a reference for clinical diagnosis. PATIENTS AND METHODS: 74 patients diagnosed as central-type lung cancer were selected. They included 34 cases of squamous carcinoma and 40 cases of non-squamous carcinoma. 256-slice spiral CT bronchial artery imaging examination was performed for patients in the two groups. The 3D reconstruction technique was used in a stand-alone workstation, using different rotation axis to observe space anatomical details of the bronchial artery and to compare development ratio of the bronchial artery, artery diameter, diameter of tumor and developing condition of the pulmonary artery. RESULTS: It was found that left side, right side and both sides developing ratios of a bronchial artery in the squamous carcinoma group were higher than the other group. Moreover, the average diameter of the artery and diameter of the tumor was significantly higher than non-squamous carcinoma group. The occurrence rates of compression and narrowing on the pulmonary arterial branch at tumor side were significantly increased (p<0.05). CONCLUSIONS: There were different 256-slice spiral CT bronchial artery imaging results for different pathological types of central-type lung cancer, which has a certain reference value for clinical diagnosis.
