“…Both MRCP techniques employed here allowed for visualization of the dilated bile and pancreatic ducts and side branches; this was consistent with previous series (24,33). Moreover, the use of multisection thin-slice MRCP facilitated additional complementary information by simultaneous visualization of pancreatic parenchyma, duodenum and adjacent structures, e.g.…”

Single-shot thick-slab MRCP and multisection MRCP provide complementary results; however, single-shot MRCP had superior image quality. Moreover, assessment of ductal morphology with MRCP alone facilitated the diagnosis of different pathologic conditions of the pancreatobiliary system in the majority of patients. However, with the addition of T2- and T1-weighted sequences the overall diagnostic accuracy was significantly improved and thus we consider that a comprehensive MR approach should comprise both MRCP techniques and parenchymal sequences.

“…MRCP is now accepted as one of the standard MR techniques for noninvasive evaluation of the pancreatobiliary tracts. [1][2][3][4] The 2D SSFSE sequence was widely used for MRCP because of the very short acquisition time, mainly to evaluate extrahepatic bile and pancreatic ducts and the gallbladder. 1,2 Three-dimensional volume acquisitions have been introduced using FSE, gradient echo, and echo planar methods.…”

“…MRCP using 2D SSFSE can be obtained within 2 s, but this might be not sufficient to provide information for nondilated pancreatic ducts and high-order branches of the bile ducts. 1 Compared with the 2D SSFSE technique, the 3D technique with FSE can provide higher signal-tonoise ratios, and thinner imaging sections can be obtained. However, one of the major drawbacks for 3D FSE imaging is its very long acquisition time.…”

Signal intensity (SI) changes of pancreatic parenchyma were evaluated after intravenous administration of secretin using T2-weighted single-shot spin-echo echo-planar imaging (EPI) to assess this method as a magnetic resonance (MR) test of pancreatic exocrine function. Nine volunteers were studied with serial single-shot EPI of the pancreas for 15 minutes after the injection of secretin or saline. The normal pattern of pancreatic SI change was demonstrated after intravenous injection of secretin, a single peak at 3-4 minutes in the head, body, and tail, followed by a gradual decrease in SI. Saline injection did not induce a significant SI change. There was no statistical difference in the peak contrast ratios (first mean, 1.21-1.25, vs. second mean, 1.18 -1.22) and peak times (first mean, 3.2-3.7 minutes, vs. second mean, 3.1-3.6) in a repeat study. By evaluating the pattern of time-response curves obtained from serial T2-weighted EPI after secretin injection, pancreatic exocrine function may be directly assessed at the level of the head, body, and tail.
