Fig. 1A —35-year-old woman with remote cholecystectomy who was
referred for abdominal pain. Coronal 2D thick-slab conventional (A) and
SENSE-implemented (B) single-shot fast spin-echo (SSFSE) images show
normal biliary system. Note increased background noise in SENSE-implemented
image (B) obscuring right posterior hepatic duct and segmental branches
of left hepatic duct.

Fig. 2A —23-year-old man who presented with suspected pancreatitis.
Coronal 2D thick-slab conventional (A) and SENSE-implemented (B)
single-shot fast spin-echo (SSFSE) images show normal biliary system. Note
increased background noise in SENSE-implemented image (B) with
corresponding increase in edge enhancement of right hepatic ducts
(arrowheads, B).

Fig. 3A —49-year-old woman after cholecystectomy who presented with
elevated liver function enzymes. Coronal 2D thick-slab conventional (A)
and SENSE-implemented (B) single-shot fast spin-echo (SSFSE) images
show normal biliary system and pancreatic duct. Two-dimensional thick-slab
SENSE-implemented sequence (B) depicts medial segment of left hepatic
duct (arrow, B).
