BACKGROUND Magnetic field markings are occasionally used at MRI sites to provide visual feedback of magnetic field strength at locations within the MRI scan room for safety purposes. In addition to magnetic field line markings, relative magnetic forc

Purpose: To present a dual-pathway multi-echo steady state sequence and reconstruction algorithm to capture T 2 , T 2 ∗ and field map information. Methods: Typically, pulse sequences based on spin echoes are needed for T 2 mapping while gradient ec

Purpose Dual-pathway sequences have been proposed to help improve the temperature-to-noise ratio (TNR) in MR thermometry. The present work establishes how much of an improvement these so-called "PSIF-FISP" sequences may bring in various organs and ti

Purpose Magnetic resonance spectroscopic imaging (MRSI), under low-spatial resolution settings, often suffers signal contamination from neighboring voxels due to ringing artifacts. Spatial localization can be improved by constraining the point-spread
