A, Stack of coronal single-shot fast spin-echo images through liver and biliary tree (field of view, 36 cm; slice thickness, 5 mm, interval, 6 mm; matrix, 320 × 224. TE is 70 milliseconds. Parallel imaging acceleration factor is 2. Stack was obtained during two separate breath-holds. Notice how diaphragm and liver bounce up and down on every other image. Although patient held breath satisfactorily, breath-hold position was different for the two acquisitions. Images are difficult to scroll through, and a small gallstone could potentially be missed if it moved in and out of the imaging planes.

B, Stack of coronal single-shot fast spin-echo images through liver and biliary tree (field of view, 36 cm; slice thickness, 5 mm, interval, 6 mm; matrix, 320 × 224. TE is 70 milliseconds. Parallel imaging acceleration factor is 2. Stack was obtained using respiratory triggering. Notice how diaphragm and liver are in same position on each image. No misregistration is seen.
