ZTE image encoding was combined with Burst imaging by reversing segments of 3D radial spokes in both time and amplitude. This recalls gradient echoes for each spokes/excitation, yielding images with T2* weighting. By adding a pair of refocusing pulses with the appropriate weight period, it is also possible to obtain spin-echoes, leading to T2-weighted images. Data is reconstructed using...

This work investigates super-resolution reconstruction and deconvolution of perfusion arterial spin labelling (ASL) images using a high-resolution T1-weighted MRI with the aim of reducing the partial volume effect on the estimated cerebral blood flow (CBF). The MR acquisition matrix was factorized to model the down-sampling and blurring of the underlying ASL images, as well as MR coil...

Inductively coupled plasma mass spectrometry (ICP-MS) of brain tissue has confirmed that both R2* and magnetic susceptibility increase linearly with the tissue iron concentration in humans without neurological diseases. However, being related to mesoscopic magnetic field inhomogeneities, R2* depends not only on the voxel-average concentration but also on the distribution of iron in the tissue....

Functional Quantitative Susceptibility Mapping (fQSM) is a recent method that, based on the same acquisition technique as conventional functional Magnetic Resonance Imaging (fMRI), has two very appealing features: it is quantitative and it is less affected by non-local effects than the Blood Oxygenation Level-Dependent (BOLD) signal. Here, for the first time, the response of the auditory...
