![]() ![]() The minimum repetition time TR (sampling rate =1/TR) depends on number of slices: for full coverage 36-46 slices TR= 1.5 - 2.0 s.Minimum time per slice is 42 µs at TE=30 ms, (echo-spacing in EPI, esp = 440 - 460 µs at resolution nx= 64-72).Our gre-epi is a slightly modified version of the product pulse sequence The Gradient Echo EPI (echo-planar imaging) is a preferable option at 3 Tesla over spin echo or asymmetric spin echo. 4.4 Quantitative Susceptibility Mapping (QSM).4.3 MR Angiography, Venography (non-contrast).4.2 T1, T2, & T2* - relaxation times mapping.4.1 Magnetisation Transfer Imaging - qMT-MRI.3.5 Intra-voxel incoherent motion (IVIM).3.2 Diffusion Tensor Imaging MRI and TBSS processing.2.3 Surface Coils Intensity Correction "PURE™ ".1.2 FMRI: slice order, slice timing, slice orientation. ![]()
