The only thing worth mentioning was a signal-loss area in the common bile duct that might have suggested narrowing or occlusion (Figure 2).
T1-weighted fat-saturated coronal image acquired 40 minutes post intravenous contrast injection, revealing fistula with the internal opening in the fundus of the gall bladder.

T1-weighted fat-saturated late-phase images obtained 40 minutes after application of 0.025 mmol/kg of Gd-EOB-DTPA revealed a bile fistula with the internal opening in the fundus of the gall bladder (Figure 3). Those images in correlation with CT scans of the drained peritoneal cavity taken before exposed that the tract of the fistula corresponded with the tract of one of the drains placed in the abdominal cavity after peritonitis (Figure 4).
CT sagittal image (A) - drain in the abdominal cavity. T1-weighted fat saturated sagittal image (B) - bile fistula corresponding with the tract of the drain.

T1-weighted fat saturated sagittal image excluded narrowing of the common bile duct suspected in a regular MRCP study

What is more, it revealed no narrowing or occlusion in the common bile duct as the flow of gadoxetic acid through that zone seemed to be undisturbed (Figure 5).
