Objective To evaluate the imaging quality of Coronary MRA(CMRA)from targeted volume vs whole heart acquisitions in visualizing coronary arteries with qualitative ***:Twenty volunteers were examined with CMRA at 3T by using targeted volume vs whole heart *** and quantitative coronary of CMRA was performed in 20 volunteers by using"Soap-Bubble"*** imaging quality score was assessed according visualizing and the average vessel length、diameter and sharpness of coronary arteries can be *** Using targeted volume acquisition,the average vessel length of RCA,LM+LAD and LCX was 112±31mm、98±14mm、51±11mm,the average vessel diameter was 3.0±0.4mm、2.9±0.3mm、3.0±0.3mm and the sharpness was 48±11%、44±13%、43±15%.Using whole heart acquisition,the average vessel length of RCA,LM+LAD and LCX was106±24mm、94±15mm、47±14mm,the average vessel diameter was 3.2±0.3mm、3.0±0.3mm、3.1±0.2mm and the sharpness was 37±14%、36±9%、34±13%.There is a significantly difference in sharpness and imaging quality score between targeted volume and whole heart acquisition(P<0.05),but no obviously difference in length and diameter(P>0.05).Conclusion The targeted volume acquisition scan provided sharper images and better overall image quality score than whole heart *** from targeted volume acquisition is recommended.
