Synopsis

A study was carried out on the effect of Gadoxetate disodium (Gx) on the accuracy of liver fat content determined by 2-echos and 6-echos VIBE Dixon in rabbits with nonalcoholic fatty liver disease in hepatobiliary specific phase. Proton density fat-fraction (PDFF) before and 13min. and 17min. after Gx enhancement had strong correlation with that of histopathology (r22E= 0.7643-0.8014 vs. r26E= 0.8208-0.8536). PDFF measured by 6E-VIBE Dixon was stable and reliable, especially for that before Gx enhancement(r26E= 0.8536). PDFF measured by 2E-VIBE Dixon fluctuated to some extent, however, it could be effectively corrected in the specific hepatobiliary phase after Gx enhancement.
