| Popis: | To assess the impact of hepatobiliary phase images obtained during intravenous gadoxetate disodium-enhanced liver MRI in the planning of image-guided liver tumor ablations. This institutional review board-approved retrospective study included 34 patients (21 men, 13 women, ages 25–80) who underwent 36 liver MRI examinations with gadoxetate disodium within 12 weeks prior to image-guided thermal ablation of 62 liver tumors during 36 procedures. Visibility of bile ducts, subdivided by branch order, on hepatobiliary phase images was compared to standard MRI sequence images by an attending abdominal radiologist and fellow. Interventional decision making (whether or not to ablate and technical plan) using hepatobiliary phase images was compared with standard MRI sequences by the ablationists. The technical success and adverse events of ablation procedures were noted. Bile duct visibility was significantly increased by at least one branch order in 18/36 (50%) examinations (p |
