Abstract:
Objective To observe the characteristics of different level of normal abdominal aorta’s time-flow,time-velocity curve and to investigate the hemodynamic factors in role of the occurrence and development of abdominal aorta’s disease.Methods PC-MRI scanning was performed on 60 normal volunteers T12/L1-L4/5 disc at the level of abdominal aorta,time-flow and time-veloci-ty curve were generated respectively.The characteristics of blood flow curves at different levels of abdominal aorta were observed. Results The time-flow,time-velocity curve of the normal abdominal aorta in different levels have 2nd phase (no diastolic reflux) and 3rd phase (diastolic reflux).Conclusion The characteristics of blood flow curves of different levels of abdominal aorta are dif-ferent.
