Abstract：Objective The application value of Test bolus(TB)technology and Bolus tracking(BT)technology in CTPA was compared and studied.Methods Retrospective analysis was conducted on 206 patients who underwent CTPA in our Hospi-tal.The same equipment and the same scanning parameters were applied.Enhanced scanning technology was adopted BT technol-ogy or TB technology.There were 67 cases in BT technology group and 139 cases in TB technology group.The image was evalu-ated subjectively and objectively,and the unified standard was applied.The results of image quality of the two groups were statis-tically analyzed by SPSS 22.0 software package,and the difference was statistically significant(P<0.05).Results The aver-age CT value of MPA,the average CT value of PLPV and the failure rate of initial scan in TB group were lower than those in BT group(P<0.05).In terms of CT value difference between MPA and PLPV and subjective score of image quality,TB technology group was greater than BT Technology Group(P<0.05).Conclusion.Compared with BT technology group,TB Technology Group has higher image quality of pulmonary artery,lower failure rate,less dose of contrast agent and higher clinical application value.
