Purpose: The aim of this study was to compare non-contrast 3T renal MRA with that of 1.5T unit.\nM ethods and M aterials : We performed renal MRA in twelve volunteers using a 1.5T and 3T unit. For\nrenal MRA, 3D SSFP sequence was used. For quantitative evaluation,ROI was set on the aorta,main\nstems of bilateral renal arteries, and IVC, measuring flow signal at each point. Signal intensity ratio\n(SIR) of renal artery relative to the parenchyma and IVC were calculated. For subjective analysis,two\nreaders evaluated visual quality. Results : SIR of the both renal artery on 3T MRA were significantly\nhigher than those on 1.5T (p＜0.01). On subjective analysis,the mean visualization score of renal main\nstem showed no statistically significant difference. However,the scores of the peripheral branches on 3T\nwas significantly higher than those of 1.5T bilaterally(p＜0.05). IVC showed significantly lower signal\nratio on 3T relative to that on 1.5T. Conclusion : 3T MRA showed superior demonstration of renal\narteries compared with 1.5T MRA. The intraparenchymal peripheral branches are especially well\ndemonstrated on 3T MRA. Decreased venous signal on 3T system contributed to the selective arterial\ndemonstration. |
