DOI: 10.1177/000992289303200203 Evaluation of Cavernous Transformation Of the Portal Vein by Magnetic Resonance ImagingDepartment of Pediatrics, Division of Pediatric Gastroenterology and Nutritional Support, Emory University School of Medicine and Egleston Children's Hospital, Atlanta, Georgia

Department of Pediatrics, Montefiore Medical Center, Albert Einstein Medical Center, Bronx, New York We describe two children who underwent magnetic resonance imaging (MRI) as part of the evaluation of isolated splenomegaly after Doppler ultrasound was unable to identify the portal vein. The diagnosis of cavernous transformation of the portal vein and the normalcy of the biliary tract and hepatic architecture were confirmed by MRI. Because of the risks associated with computed tomography (CT) and angiographic evaluation of such patients, the use of MRI, a noninvasive modality, in the evaluation of pediatric patients requires further consideration.
