Applied Discussion of "Soap-Bubble" Quantitative Analysis of Coronary MRA / 实用放射学杂志

ABSTRACT

Objective To introduce the applied value of Soap-Bubble reformatting and quantitative analysis of coronary MRA.Methods Reformatting and quantitative coronary of 3D coronary MRA were performed in twenty cases by using Soap-Bubble visualization following computer-assisted image segmentation respectively.The average vessel length,diameter and sharpness of coronary vessel can be measured.The imaging of coronary vessel was quantitative analyzed.Results 3D coronary MRA was successfully completed in 20 cases.The average vessel length of RCA /LM+LAD/LCX was(111?31) mm/(84?14) mm/(48?12) mm.The average vessel diameter of RCA /LM+LAD/LCX was(3.0?0.4 mm)/(2.9?0.3) mm/(2.4?0.2) mm.The sharpness of RCA /LM+LAD/LCX was(44?13)%/(43?15)%/(31?18)%.Conclusion Soap-Bubble enables the simultaneous display of multiple coronary segments in one 2D representation.The coronary vessel can be quantitative analyzed.
