Multi-Echo T2* MRI Identifies Neonatal Hemochromatosis via Extrahepatic Iron Patterns

Neonatal liver failure is a critical emergency often resulting in fetal loss or rapid postnatal demise if the underlying etiology is not identified and treated immediately [1, 2]. Neonatal hemochromatosis, now recognized as the phenotypic expression of gestational alloimmune liver disease, represents the most common cause of liver failure in the first weeks of life [3, 2]. While the condition is characterized by severe hepatic synthetic dysfunction and high serum ferritin levels, these markers frequently overlap with other metabolic and infectious causes of neonatal liver injury [4, 5, 6]. Definitive diagnosis traditionally relies on demonstrating extrahepatic siderosis (iron deposition) in tissues like the minor salivary glands or the pancreas, as the liver itself may show iron overload in various forms of advanced disease [3, 6, 7]. A recent study evaluates how advanced magnetic resonance imaging techniques can refine this differentiation by mapping specific patterns of organ involvement.
