WebFor TEs between this interval of 4.4 ms, their phases are shifted and for a TE at the middle of this interval (2.2 ms), they are out of phase. The signal intensity of a voxel containing fat and water oscillates with an increasing echo time, with a minimum when fat and water are out of phase, and a maximum when they are in phase. WebThis mediastinal MR examination of the thymus, if performed correctly and proficiently, should take no more than 30–45 minutes. Our mediastinal MR protocol, which we use to evaluate the thymus, is depicted in Table 1. Images exemplifying each pulse sequence can be found in Figures 1A, 1B, 1C, 1D, 1E, 1F, 1G, and 1H.
