Abstract:
:MR imaging is a noninvasive, radiation-free imaging method for evaluation of the biliary system. Continued advancements in MR imaging system hardware and sequence design, coupled with novel gadolinium chelate agents, allow for a detailed evaluation of the bile ducts and surrounding soft tissues. New hepatocyte-specific contrast agents may hold utility in the anatomic and functional evaluation of bile duct injury. MR imaging is also the imaging method of choice for bile duct tumor diagnosis, staging, and presurgical planning. Familiarity with the proper methodology of MR image acquisition and interpretation is critical for optimized diagnostic assessment.
