Unveiling Dipolar Interaction‐Driven Magnetic Field Inhomogeneities in T2 MRI Contrast Agents
Advanced Science, Volume 13, Issue 3, 14 January 2026.In this study, chemically designed nanoscale‐distance‐tuned based on silica‐coated iron oxide nanoparticles are used to investigate how dipolar interactions affect magnetic resonance imaging (MRI) contrast. By varying shell thickness, researchers modulated dipolar interactions and observed an exponential increase in transverse relaxivity (r2) that ...
