K. Koito et al., MUCIN-PRODUCING PANCREATIC TUMORS - COMPARISON OF MR CHOLANGIOPANCREATOGRAPHY WITH ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY, Radiology, 208(1), 1998, pp. 231-237
PURPOSE: To compare magnetic resonance cholangiopancreatography (MRCP)
with endoscopic retrograde cholangiopancreatography (ERCP) in the det
ection of mucin-producing pancreatic tumors. MATERIALS AND METHODS: Th
e authors retrospectively reviewed MRCP and ERCP images obtained in 28
patients with mucin-producing pancreatic tumors. Detectability of the
pancreatic duct and its branches intraductal cystic:lesions,: and int
racystic nodules or septa was assessed. RESULTS: MRCP depicted cystic
dilated ductal branches significantly better than did ERCP (P <.001).
The difference in the number of nodules, or septa_ detected with MRCP
compared with ERCP was not significant. MRCP, however, simultaneously
showed not only the main pancreatic duct but also the cystic lesions;
this was not always possible with ERCP. CONCLUSION: MRCP appears to be
more:effective and less invasive than ERCP to evaluate changes in the
size and extent of tumors and to determine if new lesions appear, as
well as to follow up mucin-producing pancreatic tumors.
