Iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) of the wrist and finger at 3T: comparison with chemical shift selective fat suppression images.
To compare fat-suppressed magnetic resonance imaging (MRI) quality using iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) with that using chemical shift selective fat-suppressed T1-weighted spin-echo (CHESS) images for evaluating rheumatoid arthritis (RA) lesions of the hand and finger at 3T. ⋯ IDEAL could compensate for the effects of field inhomogeneities, providing uniform FS of the hand and finger than did the CHESS-T1-SE sequence.

Regional values of diffusional kurtosis estimates in the healthy brain.
To provide estimates of the diffusional kurtosis in the healthy brain in anatomically defined areas and list these along previously reported values in pathologies. ⋯ DKI parameter estimates MK and RK varied depending on the anatomical region and varied with age in pooled WM and GM data. MK estimates in the internal capsule, corpus callosum, and thalamus were consistent with previous studies. The range of values of MK and RK in healthy brain overlapped with that in pathologies.
