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.

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

1. To determine short-term interval changes in T2 maps of knee cartilage of healthy boys before and after a 2-minute knee-squat exercise at 1.5T and 3T MRI; 2. To determine interval changes in T2 maps pre-exercise at 1.5T vs. 3T, and post-exercise at 1.5T vs. 3T; 3. To determine interval changes pre- and post-exercise among minimal-, moderate-, and high-activity subjects at 1.5T and 3T; and 4. To determine inter- and intra-reader reliability of 1.5 and 3T values. Read More
