Abstract：Objective:To investigate the clinical value of the 128-slice spiral CT combined with ECG-gated scanning technology in the bronchial artery imaging. Methods:Data of 124 cases with chest angiography (CTA) in our hospital were retrospectively analyzed, among which scan data of 72 cases underwent routine chest CTA were listed in the control group, 52 cases of ECG-gated were listed included in the observation group, bronchial artery opening position, course, the anatomical relationship with adjacent tissues and bronchial artery clarity were compared and analyzed.Results:33.33% (24/72) in the control group bronchial artery displayed clearer, 58.33% (42/72), bronchial artery fuzzy, 8.33% (6/72) found no bronchial artery; observation group, 52 cases of bronchial artery showed all ,86.54% (45/52) of bronchial artery were clearly displayed , and 13.46% (7/52), bronchial artery appeared blurred.Conclusions:Compared with conventional chest angiography, the joint ECG-gated 128-slice spiral CT scanning technology can clearly show the bronchial artery opening position, shape, running their organization and the adjacent relationship; it has an important clinical value for bronchial artery-borne diseases treatment especially the evaluation before interventional treatment.
