On the coronal scout, the lumen of the gallbladder is sharply divided into low signal medially and high signal laterally with a "level" appearance suggesting layering sludge. However, the axial T2W shows no sludge in the gallbladder. This finding is attributed to cross-excitation artifact. This was an incidental finding.
The main area of concern was in segment 6 metastasectomy bed which shows nonspecific hyperintensity on axial T2 fat sat images.
