title: Magnetic resonance imaging of the abdomen: applications in the oncology patient.
abstract: Cross-sectional imaging of the abdomen in oncology patients presents unique challenges and opportunities. A close working relationship between the oncologist and radiologist is essential for the exchange of the clinical and imaging information necessary for optimizing patient diagnosis and management. Compared to helical computed tomography (CT), magnetic resonance imaging (MRI) of the abdomen and pelvis offers important advantages, including superior soft-tissue contrast. The multiplanar capabilities of MRI allow for direct coronal or sagittal imaging, providing a truer anatomic presentation of abdominal and pelvic masses. Recent advances in MRI, including the use of intravenous (i.v.) and oral contrast agents, the development of high-performance imagers, and improved surface coil designs, facilitate more rapid abdominal imaging with superior image quality. All of these features combine to produce a versatile imaging examination with exquisite sensitivity for depicting abdominal and pelvic tumors. In this article, we will review the clinical applications for hepatic and extrahepatic abdominal MRI in the oncology patient. The MRI techniques and protocols described can be applied to most commercially available high-field magnetic resonance imagers.
