The sequence was modified so that for dual-spin-echo scans, the polarity of the second degree pulse is inverted relative to the first This causes off-resonance signal from fat to get defocused and thus help reduce fat-shift artifacts See Sarlls et. Robust fat suppression at 3T in high-resolution diffusion-weighted single-shot echo-planar imaging of human brain. Reduction of eddy-current-induced distortion in diffusion MRI using a twice-refocused spin echo. Tournier et al. For a 45 degrees crossing, the minimum b-value required to resolve the fibre orientations was The b-values file contains a set of numbers one for each acquired volume that describe the b-value of the corresponding volume. The b-vecs file contains a triplet of numbers for each acquired volume, describing the diffusion-weighting direction for the corresponding volume. Thus, you nifti file will contain 66 volumes. The b-vals file will contain 66 numbers six 0's, fllowed by 60 's and the b-vecs files will contain 66 triplets describing the DW directions for each volume the triplets for the first 6 non-DW volumes are meaningless and can be ignored. The scan coverage and matrix size are the same for the calibration and the SMS scans. The ART scan is quieter, but the acquisition will be slower and the geometric distortion will be worse. Consult with us if you would like to set up your own diffusion gradient scheme. The pe1 scan is a repeat of the pe0 scan with reversed phase encoding direction.

Perfec condition. Great book for MRI parameters and protocol selections for both new and experienced technologists, as well as instructors. Good reference book.

Great book, what I expected. I use this book as an MRI student. I would recommend this to anyone pursuing or in the MRI field itself. The book is good for what it is. The parameters are good as a general ballpark and not as a finished recommendation. Also although the book covers the positions for scan references it does not cover the recommended or preferred scan sequences or the 'whys' associated with such options.

The lasers enabled prostate and seminal vesicles in CT because of the the patients to be positioned for their MRIRT scan more similarity in Hounsfield numbers with the surrounding closely to their CT set-up position and thereby resulted tissue, which results in a lack of contrast.

Multi-shell diffusion Multi-shell with different TE: this set of scans are set up for a series of different b-values and number of diffusion directions to collect multi-shell diffusion data. The optimized TE for different b-values are different, so to get the best SNR possible we set up separate scans for each b-value.

All scans have the same following acquisition parameters: SMS factor 3, axial slices, 2.
