The application of dual-source Flash post-processing software for the evaluation of bronchial artery / 实用放射学杂志

ABSTRACT

Objective To evaluate feasibility and time efficiency of dual-source flash post-processing software (Bone Reading)for reconstruction of bronchial artery.Methods The imaging data of 70 patients with suspected bronchial artery dilatation who underwent bronchial artery-CTA were evaluated by 2 independent radiologists.First,the related contents of bronchial artery such as origination,number, type,route and lumen diameter were evaluated by multiple planar reconstruction (MPR),maximum intensity projection (MIP)and volume rendering technique (VRT).The results and process time were recorded.After a month,the post-processing software(Bone Reading)was used to evaluate the same contents.Results There was very good correlation between both readers for both reading methods without significant differences.There was significant difference of process time between with regular method and with Bone Reading (P<0.05)for both readers.Process time could be decreased by approximately 35%.Conclusion The application of CT software (Bone Reading)is feasible in the CTA of bronchial artery.This method may gain a significant time saving in comparison to regular method.
