Abstract：Objective: Using spiral CT angiography(CTA) for assessing the changes of bronchial artery(BA) in central and peripheral lung cancer, the difference in BA changes with tumor size and location. Methods: The study was approved by the institutional research board. Fifty patients with pathologically confirmed lung cancer(25 cases in each of the central and peripheral lung cancer), were divided into nodular group(tumor diameter ≤30 mm) and mass group(tumor diameter >30 mm); 30 normal individuals were included. Pre- and post-enhanced chest CT scan were performed in all of the cases. CTA was processed from the data of arterial phase CT scan after contrast material was injected. Post-processing included multiple plane reconstruction(MPR), maximum intensity projection(MIP), and volume rendering technique(VRT). The origins, morphological features of the BA and its relationship with the tumor were carefully observed. Results: All of the 30 cases of normal control group showed BA, 50 arteries on the right side(average 1.7/case), 53 arteries on the left side(average 1.8/case). In 50 cases of lung cancer, 90 arteries were showed(an average of 1.8/case). The average diameter of BA was 1.4 mm in the control group. The average diameter of BA was 1.8 mm in the 12 central lung cancer(nodule group), 13 cases the average diameter was 2.9 mm in the mass group, total average diameter was 2.6 mm. The average diameter of BA was 1.5 mm in the 9 peripheral lung cancer nodule group. The average diameter was 2.0 mm in the 16 cases of the mass group, total average diameter was 1.8 mm. BA of peripheral lung nodule group compared with normal control group, there was no significant difference(P>0.05). There was significant difference in internal diameter of BA in mass group of peripheral lung cancer and central of the nodule group when compared with normal control group(P<0.001). The diameter of BA was significantly increased in the central lung cancer than that in the peripheral lung cancer(P<0.01). Conclusions: Spiral CT can effectively show the BA, BA changes have certain relevance with the tumor size and location.
