Diffusion MRI with pulsed and free gradient waveforms: Effects of restricted diffusion and exchange
Sign Up to like & getrecommendations! 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.
