AIM： To compare differences between volumetricinterpolated breath-hold examination （VIBE） usingtwo-point Dixon fat-water separation （Dixon-VIBE）and chemically selective fat saturation （FS-VIBE） withmagnetic resonance imaging examination.METHODS： Forty-nine patients were included, whowere scanned with two VIBE sequences （Dixon-VIBEand FS-VIBE） in hepatobiliary phase after gadoxeticacid administration. Subjective evaluations includingsharpness of tumor, sharpness of vessels, strength andhomogeneity of fat suppression, and artifacts that werescored using a 4-point scale. The liver-to-lesion contrastwas also calculated and compared.RESULTS： Dixon-VIBE with water reconstruction hadsignificantly higher subjective scores than FS-VIBE instrength and homogeneity of fat suppression （〈 0.0001）but lower scores in sharpness of tumor （P 〈 0.0001）,sharpness of vessels （P = 0.0001）, and artifacts （P= 0.034）. The liver-to-lesion contrast on Dixon-VIBEimages was significantly lower than that on FS-VIBE（16.6% ± 9.4% vs 23.9% ± 12.1%, P = 0.0001）.CONCLUSION： Dixon-VIBE provides stronger andmore homogenous fat suppression than FS-VIBE, whilehas lower clarity of focal liver lesions in hepatobiliaryphase after gadoxetic acid administration.Key words： Dixon-volumetric interpolated breath-holdexamination; Fat saturation-volumetric interpolatedbreath-hold examination; Gadoxetic acid; Volumetricinterpolated breath-hold examination; Magnetic
