Abstract:
Objective To investigate the image quality differences of clinical conventional contrast injection solutions and personalized injection program in 64 -slice spiral coronary CT angiography (CTA),thus to obtain the CTA optimum contrast agent injection protocol.Methods 64 patients who needed to receive CTA angiography,were randomly divided into observation group and control group,32 cases in each group.The control group underwent rou-tine clinical angiography contrast agent injection protocol,the observation group received personalized contrast injec-tion solutions,the image difference of the two groups was compared.Results Compared with the control group,the right ventricular (RV)and pulmonary CT value of the observation group increased significantly[(272.4 ±72.3)HU, (372.1 ±78.2)HU],the differences were statistically significant (t =3.827,3.921,all P <0.05).CT values of left ventricular (LV),ascending /descending aorta had no significant differences between the two groups (P >0.05). Compared with the control group,the advantages of septal imaging of the observation group was significant (control group 3 points in 20 cases,29 cases of the observation group),the difference was statistically significant (χ2 =16.023,P <0.05).Conclusion In CTA angiography,personalized contrast injection speed can effectively improve the enhancement degree of right heart,so that the right ventricular septal has clearer image,provides a great conven-ience for clinical diagnosis and prognosis,it is worth further clinical application.
