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…
Considerations and recommendations from the ISMRM Diffusion Study Group for preclinical diffusion MRI: Part 2 -- Ex vivo imaging: added value and acquisition
Kurt G Schilling, Francesco Grussu, Andrada Ianus +54
The value of preclinical diffusion MRI (dMRI) is substantial. While dMRI enables in vivo non-invasive characterization of tissue, ex vivo dMRI is increasingly used to probe tissue…
Considerations and Recommendations from the ISMRM Diffusion Study Group for preclinical diffusion MRI: Part 1 -- In vivo small-animal imaging
Ileana O Jelescu, Francesco Grussu, Andrada Ianus +54
Small-animal diffusion MRI (dMRI) has been used for methodological development and validation, characterizing the biological basis of diffusion phenomena, and comparative anatomy.…
Incorporating the effect of white matter microstructure in the estimation of magnetic susceptibility in ex-vivo mouse brain
Anders Dyhr Sandgaard, Valerij G. Kiselev, Rafael Neto Henriques +2
Accurate estimation of microscopic magnetic field variations induced in biological tissue can be valuable for mapping tissue composition in health and disease. Here, we present an…
To mask or not to mask? Investigating the impact of accounting for spatial frequency distributions and susceptibility sources on QSM quality
Anders Dyhr Sandgaard, Noam Shemesh, Sune Nørhøj Jespersen +1
Estimating magnetic susceptibility using MRI depends on inverting a forward relationship between the susceptibility and measured Larmor frequency. However, an often-overlooked cons…
Tensor denoising of high-dimensional MRI data
Jonas L. Olesen, Andrada Ianus, Leif Østergaard +2
The signal to noise ratio (SNR) fundamentally limits the information accessible by magnetic resonance imaging (MRI). This limitation has been addressed by a host of denoising techn…
