Axonal microstructure and compartmentalization impact the orientation and time dependence of mesoscopic transverse relaxation
Anders Dyhr Sandgaard, Rafael Neto Henriques, Noam Shemesh +1
In biological tissue, MR transverse relaxation stems from mechanisms spanning multiple scales, from molecular dipole-dipole interactions to mesoscopic field variations driven by ti…
Considerations and recommendations from the ISMRM Diffusion Study Group for preclinical diffusion MRI: Part 3 -- Ex vivo imaging: data processing, comparisons with microscopy, and tractography
Kurt G Schilling, Amy FD Howard, Francesco Grussu +55
Preclinical diffusion MRI (dMRI) has proven value in methods development and validation, characterizing the biological basis of diffusion phenomena, and comparative anatomy. While…
The Larmor frequency shift of a white matter magnetic microstructure model with multiple sources
Anders Dyhr Sandgaard, Noam Shemesh, Leif Østergaard +2
Magnetic susceptibility imaging may provide valuable information about chemical composition and microstructural organization of tissue. However, its estimation from the MRI signal…
MP-PCA denoising of fMRI time-series data can lead to artificial activation "spreading"
Francisca F. Fernandes, Jonas L. Olesen, Sune N. Jespersen +1
MP-PCA denoising has become the method of choice for denoising in MRI since it provides an objective threshold to separate the desired signal from unwanted thermal noise components…
Double diffusion encoding and applications for biomedical imaging
Rafael N. Henriques, Marco Palombo, Sune N. Jespersen +3
Diffusion Magnetic Resonance Imaging (dMRI) is one of the most important contemporary non-invasive modalities for probing tissue structure at the microscopic scale. The majority of…
Ultrafast functional magnetic resonance imaging reveals neuroplasticity-driven timing modulations
Rita Gil, Francisca F. Fernandes, Noam Shemesh
Functional Magnetic Resonance Imaging (fMRI) is predominantly harnessed for spatially mapping activation foci along distributed pathways. However, resolving dynamic information on…
