Abstract:
Objective:To study the feasibility of using MRI in detection and qualitative analysis of atherosclerotic plaque in rabbits.Methods: The atherosclerotic model was established in rabbits with high cholesterol diet.The experimental animals received T_(1)WI,T_(2)WI,PDWI and TOF sequences scanning and B ultrasound examination.Results: The atherosclerotic model was successfully established in rabbits.T_(1)WI,T_(2)WI and PDWI sequences scanning showed thickening of aortal wall and the plaque showed equal,high or low signal intensities,which was in good accordance with the pathological examination results.The atherosclerotic plaques were successfully detected and analyzed by MR and MR had higher accuracy than ultrasound examination.Conclusion: MR can be used for detection of atherosclerotic plaque and for qualitative analysis of the plaque.
