[MR imaging of the pancreas]

Area of Science:

• Radiology
• Medical Imaging
• Gastroenterology

Context:

• Magnetic resonance (MR) imaging has significantly advanced pancreatic imaging capabilities.
• Noninvasive visualization of pancreatic ducts and parenchyma is now achievable.
• MR cholangiopancreatography (MRCP) is a key tool for pancreatic assessment.

Purpose:

• To review the evolving role of MR imaging and MRCP in diagnosing pancreatic diseases.
• To highlight the utility of MR techniques in evaluating pancreatic ductal anatomy, parenchyma, and various pathologies.
• To discuss the diagnostic contributions of MR in conditions like pancreatitis, neoplasms, and other specific pancreatic disorders.

Summary:

• MR imaging provides detailed noninvasive visualization of the pancreas and its ducts.
• MRCP is effective for detecting anatomical variants like pancreas divisum.
• While contrast-enhanced CT remains standard for acute/chronic pancreatitis with calcifications, MR and secretin-enhanced MRCP are valuable for pseudocysts and disruptions.
• MR imaging is crucial for characterizing cystic pancreatic lesions and their ductal communication.
• MRCP and MR are also useful for diagnosing lymphoplasmocytic and groove pancreatitis.

Impact:

• MR imaging and MRCP enhance the noninvasive diagnostic capabilities for a wide spectrum of pancreatic diseases.
• These techniques offer critical information for characterizing pancreatic lesions, especially cystic neoplasms.
• The findings support the integration of advanced MR techniques into the diagnostic workup of pancreatic pathologies, complementing CT imaging.
