The SSFSE sequence used in evaluating the pregnant patient is a common staple of MRCP examinations and an assessment of the biliary tract is inherent to the protocol, almost always captured with the large, coronal field-of-view.
When there is laminar flow in the ureter, a central, poorly defined filling defect may be seen on the SSFSE sequence (Figure 2).
imaging accurately shows the biliary and pancreatic ducts, peripancreatic inflammation, pseudocysts, and other fluid collections without the administration of intravenous contrast.

or HASTE is that the individual images are acquired in <1 second, allowing motion-free images in patients, even without patient cooperation.
