Abstract
Objective: to estimate the informative value of magnetic resonance imaging (MRI) and MR cholangiopancreatography for diagnosing changes in the parenchyma and duct system of patients with suspected and/or diagnostically established chronic pancreatitis.
Material and methods. MRI was carried out in 120 surgical patients with suspected and/or diagnostically established chronic pancreatitis, by using a Siemens Magnetom Impact i.O T MRI system. The study protocol encompassed standard gradient sequences and MR cholangiopancreatography.
Results. No visual signs of changes were found in the pancreatic parenchyma and main pancreatic duct in 7 (5.8%) patients. There were undetectable MR changes in the pancreas and duct system in 12 (10.0%) patients. Mild changes in the pancreas were visualized in 17 (14.2%). Its moderate changes as diffusely reduced signal intensity, gland irregularities, and dilated main pancreatic duct with uneven ecstasized and shortened side branches were revealed in 24 (20.0%) patients. Most examinees (и 60 (50.0%)) had obvious pancreatic changes.
Conclusion. Standard MRI and MR cholangiopancreatography in evaluating chronic pancreatitis can visualize pancreatic parenchymal signal changes and altered ducts particularly in patients with suspected chronic pancreatitis, the signs of pancreatic parenchymal atrophy and fibrous changes and estimate pancreatic sizes and duct system changes.
