The neonatal liver may be affected by a variety of congenital and acquired diseases. Imaging has an important role in the workup and management of many neonatal hepatic abnormalities. Some aspects of imaging the liver and imaging findings are specific to neonatal patients when compared with those in older children. Therefore, selecting and tailoring the imaging technique for each indication in the neonate is important for optimal care, with minimal invasiveness. Common indications for imaging include incidental focal lesions, neonatal liver failure, cholestasis, and sepsis. US is the primary imaging modality, and for most conditions it is the only imaging modality required. MRI is the next modality after US for neonatal liver assessment and is especially required for complete assessment and staging of neoplasms, vascular abnormalities, and diagnosis of neonatal hemochromatosis. CT can be used when MRI is not available and should be used sparingly and in patients with acute conditions such as intra-abdominal bleeding. The authors emphasize imaging modalities that can be used for assessment of neonatal liver abnormalities, the imaging appearances of normal and changing structures in the neonatal liver, and indications for imaging. Abnormalities that are described include neonatal liver failure, infections, hepatic calcifications, umbilical venous catheter-related complications, and vascular abnormalities. ©RSNA, 2024 Supplemental material is available for this article.
