Velocity-compensated intravoxel incoherent motion of the human calf muscle
CONCLUSION: Velocity-compensated diffusion gradients significantly suppress the IVIM effect in the calf muscle, indicating that the ballistic limit is mostly reached, which is supported by the time dependence of the pseudo-diffusion coefficient.PMID:38688865 | DOI:10.1002/mrm.30059 (Source: Magnetic Resonance in Medicine)

Accelerated motion correction with deep generative diffusion models
CONCLUSION: We propose a flexible framework for retrospective motion correction of accelerated MRI based on deep generative diffusion models, with potential application to other forward model corruptions.PMID:38688874 | DOI:10.1002/mrm.30082 (Source: Magnetic Resonance in Medicine)

Distortionless, free-breathing, and respiratory resolved 3D diffusion weighted imaging of the abdomen
CONCLUSION: Acquisition of distortionless, diffusion weighted images is feasible during free-breathing with a b-value of 500 s/mm2, scan time of 6 min, and a clinically viable reconstruction time.PMID:38688875 | DOI:10.1002/mrm.30067 (Source: Magnetic Resonance in Medicine)

In vivo diffusion MRI of the human heart using a 300 mT/m gradient system
CONCLUSION: This work demonstrates cardiac DWI in vivo with higher b-value and higher order of motion compensated diffusion gradient waveforms than is commonly used. Increasing the motion compensation order from M 2 $$ {M}_2 $$ to M 3 $$ {M}_3 $$ and the maximum b-value from 450 to 1000 s / mm 2 $$ \mathrm{s}/{\mathrm{mm}}^2 $$ affected the MD values but FA and the angular metrics (HA and E2A) remained unchanged. Our work paves the way for cardiac DWI on the next-generation MR scanners with high-performance gradient systems.PMID:38650395 | DOI:10.1002/mrm.30118 (Source: Magnetic Resonance in Medicine)
