Diffusion MRI with pulsed and free gradient waveforms: Effects of restricted diffusion and exchange

Sign Up to like & get
recommendations! Published in 2022 at "Nmr in Biomedicine"

DOI: 10.1002/nbm.4827

Abstract: Monitoring time dependence with diffusion MRI yields observables sensitive to compartment sizes (restricted diffusion) and membrane permeability (water exchange). However, restricted diffusion and exchange have opposite effects on the diffusion‐weighted signal, which can lead to… read more here.

DOI: 10.1002/nbm.5208

Abstract: Filter exchange imaging (FEXI) is a double diffusion‐encoding (DDE) sequence that is specifically sensitive to exchange between sites with different apparent diffusivities. FEXI uses a diffusion‐encoding filtering block followed by a detection block at varying… read more here.

DOI: 10.1007/s00234-025-03672-4

Abstract: Glioblastoma (GB) is the most malignant primary brain tumor. Isolated restricted diffusion (IRD) is restricted diffusion outside the confines of enhancing tumor with no corresponding enhancement on post contrast study. The aim of our study… read more here.

DOI: 10.1007/s00261-017-1366-2

Abstract: Abstract Diffusion-weighted imaging (DWI) is an increasingly utilized sequence in the assessment of abdominal and pelvic lesions. Benign lesions containing hemorrhagic products, with conglomerates of tightly packed blood cells or fibers, can have restricted water… read more here.

DOI: 10.1007/s12028-018-00666-4

Abstract: BackgroundAbnormal restricted diffusion on magnetic resonance imaging is often associated with ischemic stroke or anoxic injury, but other conditions can present similarly. We present six cases of an unusual but consistent pattern of restricted diffusion… read more here.
