Objective To investigate the characteristics of the bronchial artery by using 64-slice spiral CT imaging, in order to grasp the anatomy structure of bronchial artery, including the origin, distribution, amount, diameter, location and the lymph nodes around, and to lay a foundation for further diagnosis of the bronchial artery pulmonary disease with 64-slice spiral CT imaging. Methods A total of 85 cases with pulmonary disease and planed to have chest CT scan in our hospital and Jiamusi University First Affiliated Hospital were collected from February 2013 to December 2014. All patients were examined by common CT and 64-slice spiral CT BA-CTA after obtaining the agreement from patients and their family members. The imaging of the bronchial artery and the lymph nodes around were observed, and the differences of condition and quality between the common CT and 64- slice spiral CT were investigated. Results The number of the single left, single right and overall meditational segmental bronchus artery demonstrated by 64-slice spiral CT BACTA was larger than common CT (P＜0.05), the difference had statistical significance. The display capability of the artery diameters and the lymph nodes around which examined by 64-slice spiral CT CTA was significantly better than common CT for P＜0.05. All the imaging quality by using 64-slice spiral CT CTA was better than common CT for P＜0.05. Conclusion It is more complete and intuitive by using 64-slice spiral CT to show the origin, branch, number diameter, location of the bronchial artery and the lymph nodes around than normal CT, which plays a important role in the diagnosis of pulmonary disease.
