【Objective】To  evaluate  the  accuracy  of  the  T1Mapping  sequence  in  determining  the  concentration  of the Gd- EOB- DTPA solution by measuring the T1values of the phantom，and to determine a better scanning sequence.【Methods】Gd-EOB-DTPA solution phantom was prepared with different concentrations（0.007-1.814 g/L）for MRI scanning（n=12）. Scanning sequences include T1weighted image（WI）sequences（opp-phase，IR，SE，T1-fl2d，T1-vibe， T1-3D）and T1Mapping sequences（VIBE_Mapping ，T1-tra-3D_Mapping，T1-fl2d_Mapping）. In T1WI，the signal intensity of the phantom solution（Sp）and that of the reference object（Sm）at the same level were measured ，and the signal to noise ratio（SNR）（Sp/Sm）was calculated. In T1Mapping，the T1 values of the phantom solution（T1p），the reference at the same level（T1m）and the background（T1n）were measured respectively，and the SNR and contrast to noise ratio（CNR）were calculated（SNR=T1p/T1n，CNR=|T1p-T1m|/T1n）. 【 Results 】 The signal intensity（SI）and relative signal intensity（RSI） determined by the conventional sequences were positively correlated with the concentration of Gd-EOB-DTPA（P<0.05），except for the SE sequence（P=0.058）. The T1 values of the phantom were negatively correlated with the concentration of Gd-EOB-DTPA，with statistically significance（P<0.05）. Among the T1Mapping sequences，the SNR and CNR of the VIBE sequence were higher than those of T1-tra-3D and T1-fl2d sequences（P<0.05）. There was no statistically significant difference between T1-tra-3D and T1-fl2d sequences（P>0.05）.【Conclusion】T1Mapping software can obtain accurate T1 values. The T1Mapping image obtained by the VIBE sequence has high quality and fast scanning speed，which is more suitable for Gd-EOB-DTPA enhanced MR examination of liver.
