The evaluation by magnetic resonance imaging of hepatic periportal fibrosis in infants with neonatal cholestasis: preliminary report.

Purpose: The aim of this study was to evaluate the potential role of magnetic resonance (MR) imaging cholangiography for the assessment of periportal fibrosis associated with neonatal cholestasis.

Methods: The authors have compared the findings on MR imaging cholangiography and on pathology in 10 infants evaluated because of neonatal cholestasis. The series included 3 patients with biliary atresia (BA), 3 patients with choledocal cyst, 2 with a neonatal hepatitis, and 2 with an inspissated bile syndrome.

MR imaging of fetal sacrococcygeal teratoma: diagnosis and assessment.

Objective: The purpose of this study was to evaluate the usefulness of MR imaging in the diagnosis and assessment of fetal sacrococcygeal teratoma and to determine if MR imaging provides information not seen on obstetric sonography.

Subjects And Methods: Twelve pregnant women were referred for fetal MR imaging of sacrococcygeal teratoma seen at obstetric sonography. The presence, size, content extension, and compressive effects of each mass were determined and correlated with the sonographic findings and with postnatal studies, including surgery and pathology.
