Temperature mapping of particles during aseptic processing via magnetic resonance imaging
… undergoing aseptic processing were studied. A variable flip angle gradient echo sequence was initially tested. With this sequence T1 maps were obtained from two images acquired in sequence with a total imaging time of approximately 25 seconds. With a T1 vs temperature calibration, temperature …

Robust Fat and Fluid Suppression in MR Imaging: Technical Developments and Advanced Clinical Applications
… from low SNR. Then, a multi-echo Dixon based variable flip angle TSE sequence was implemented for robust fat suppression with improved SNR and blood suppression, increasing the visualization of brachial plexus. The multi-echo Dixon method was later extended to single shot TSE (SShTSE) sequence …

Three-dimensional T1 quantification techniques for assessment of cartilage quality using dGEMRIC
… of B1 inhomogeneities and slab profile flip angle variations in the 3D-LL data. From in vivo and phantom measurements the methods were shown to be reliable, with T1 results that agreed very well to gold standard two-dimensional inversion recovery (2D-IR). A 3D variable flip angle …
