MRI of hepatobiliary and pancreatic disorders in pregnancy

Abstract

The most common indication for abdominopelvic imaging in a pregnant woman, excluding fetal assessment, is evaluation of abdominal pain. Although hepatobiliary and pancreatic disorders are relatively uncommon in pregnancy, they may be severe enough to put both mother and fetus in danger. Many times, preceding symptoms are nonspecific and clinical evaluation is challenging. Imaging is, therefore, essential in making an accurate diagnosis and delivering appropriate treatment that can be lifesaving for both mother and fetus. The choice of the most appropriate imaging modality is influenced by various factors that include safety for the fetus, availability, and time. While overall ultrasound remains the initial imaging modality of choice, magnetic resonance imaging (MRI) can provide important noninvasive diagnostic information due to its inherent high soft tissue contrast resolution, even without use of intravenous gadolinium-based contrast material. MRI protocols tailored to address specific clinical questions, such as MR cholangiopancreatography (MRCP), may add value to the examination.
