High-Resolution Free-Breathing Chemical-Shift-Encoded MRI for Characterizing Lymph Nodes in the Upper Abdomen

This work presents a promising magnetic resonance imaging method to depict upper abdominal LNs and to visualize their USPIO uptake. Instead of multiple Cartesian breath-hold scans, all relevant contrasts and parameters are obtained from a single free-breathing radial acquisition. The proposed method yielded higher image quality and more sensitive detection of small LNs. value analysis showed a strong linear correlation with the reference, albeit with minimal biases.
