Magnetic Resonance Imaging is a powerful tool for the detection of ferromagnetic components. This property can be used for the early detection of pathologic conditions related to liver iron overload. Neonatal hemochromatosis and hemosiderosis are conditions associated with severe liver disease. Infections like parvovirus and cytomegalovirus, metabolic conditions and gestational allo-immune liver disease can produce neonatal hemochromatosis phenotype. Fetal iron overload can be detected early by using T₂* multi-echo gradient sequence. There are only few studies reporting standard T₂* values of the fetal liver at 1.5 T. The aim of this study is to evaluated the standard T₂* values of the fetal liver using prenatal MRI with 3.0 T. Read More

Fetal intracranial volume is one of the most important parameters used in assessing normal fetal growth. Based on volumetric ultrasound (US), Virtual Organ Computer-Aided-anaLysis (VOCAL^TM) is a commonly used technique for such measurement. Magnetic resonance imaging (MRI) offers better soft tissue contrast for fetal brain imaging and is considered as one of the best tools for tissue volumetry, and as a standard for comparison. In this work we compare fetal intracranial volumes measured from MRI with those obtained from VOCAL^TM measurements in the same fetuses. Read More

Both placental vascular density and oxygenation can indicate placenta health. MRA is a powerful tool to evaluate tissue vasculature but with limited applications because of the use of contrast agents. T₂* maps can be used to estimate the placental oxygen reserve. In this work, we acquired non-contrast enhanced MRA and T₂* maps to evaluate placental vasculature and oxygenation. Read More
