Objective:The explore the feasibility of shortening the delay time of hepatobiliary phase by increasing flip angle(FA)on Gd-EOB-DTPA-enhanced MR imaging.Methods:Seventy-one patients with 107 hepatic lesions underwent gadoxetic acid-enhanced MRI with 10 min FA 20°,10 min 30°and 20 min FA 10°.Signal-to-noise ratio of liver(SNRliver),signal-to-noise ratio of lesion(SNRlesion),liver-to-lesion ratio(LLR),bile-to-paravertebral muscle ratio(BMR)were calculated and statistically analyzed in three image groups.Two r...
