Liver MRI done 2 weeks after cholecystectomy. On axial fat-suppressed T2-weighted TSE (A) and coronal T2-weighted (B) images, mild hyperintense signal is seen at the edge of the surgical resection in segment IV and V. (*) Pregnant uterus at 26 weeks of amenorrhea. Liver MRI at 7 months follow-up, on axial fat-suppressed T2-weighted TSE (C) and coronal T2- weighted (D) images, the signal hyperintensity previously seen has disappeared. On the hepatobiliary phase (axial (E) and coronal (F) view), acquired at 20 minutes after injection of gadoxetic acid (Primovist), no metastases were seen. Some metal artefacts related to surgical clips post-cholecystectomy can been seen (arrow; E).
