Fig. 4B —55-year-old man with pancreatic adenocarcinoma and suspected liver metastases shown by MRI but inconspicuous on MDCT. Axial arterial-phase gadolinium-enhanced T1-weighted fat-suppressed gradient-recalled echo MR image performed 3 days after MDCT shows several ring-enhancing liver lesions (short white arrows) suggestive of liver metastases. These lesions were not bright on T2-weighted images, suggesting bile lakes or abscesses. Patient was afebrile. These lesions were inconspicuous on MDCT. There is susceptibility artifact because of biliary stent (arrowhead) with adjacent dilated pancreatic duct en face (long arrow). Note poorly defined hypointense mass (black arrow) in pancreatic head.
