Objective To compare the image quality between large dose smart tracking technique and low dose test bolus technique for gem spectral CT pulmonary angiography(CTPA).Methods A total of 106 cases with suspected pulmonary embolism were divided into two groups.Group A(54cases)was carried out with large dose smart tracking technique.Group B(52cases)was carried out with low dose test bolus technique.We compared the image quality between the two groups.Results There were significant differences in the CT value of the right pulmonary artery and the content of iodine in the lower lobe of the right pulmonary artery of two groups(P0.01).There was significant difference of image quality between the two groups(P0.05).The rate of excellent or good image quality in group A was higher than that in group B,and the difference was statistically significant(P0.05).Conclusion Large dose smart tracking technique can track the artifacts of pulmonary artery imaging with less artifacts and uniform vascular fixation.The image quality of pulmonary artery imaging is better than that of small dose contrast agent.
