Feasibility of Applying Mb Epi Pcasl for High-resolution Whole Brain Perfusion Imaging at 7t
Target audience: Arterial spin labeling researchers, neuroimaging scientists and clinicians Purpose Ultra high fields, (≥7T), should provide significant advantages for high-resolution whole brain perfusion imaging due to greatly increased blood T1 and signal noise ratio (SNR). However, there exist several challenges: B1 and B0 inhomogeneity, high specific absorption rate (SAR) and shortened T2*...
متن کاملHigh-Resolution 7T MR Imaging of the Motor Cortex in Amyotrophic Lateral Sclerosis.
BACKGROUND AND PURPOSE Amyotrophic lateral sclerosis is a progressive motor neuron disorder that involves degeneration of both upper and lower motor neurons. In patients with amyotrophic lateral sclerosis, pathologic studies and ex vivo high-resolution MR imaging at ultra-high field strength revealed the co-localization of iron and activated microglia distributed in the deep layers of the prima...
متن کاملPeriventricular Areas Anti-Correlate with Visual Cortex in High Resolution Resting-State fMRI at 7T
Fig. 3 For an example data-set, we show a zoomed view of: A) negative/positive correlation maps (red/green) with the seed-time series in the VC, and the anatomy of the lateral ventricles in high-resolution B) magnitude and C) phase images (TE = 28.5 ms). Fig. 4 Correlation maps (red/green = negative/positive) with the seed timeseries in the VC from the second echo (TE = 28.2ms). Images for an e...
متن کاملApplications of Epi-Retractable and Co-Epi-Retractable Modules
A module M is called epi-retractable if every submodule of M is a homomorphic image of M. Dually, a module M is called co-epi-retractable if it contains a copy of each of its factor modules. In special case, a ring R is called co-pli (resp. co-pri) if RR (resp. RR) is co-epi-retractable. It is proved that if R is a left principal right duo ring, then every left ideal of R is an epi-retractable ...
متن کاملA Multi-Resolution Comparison of Single-Shot EPI, 3DFFE and PRESTO for fMRI at 7T
INTRODUCTION Single-shot Echo-Planar Imaging (EPI) is the sequence most commonly used for fMRI experiments. At high field, e.g. 7T, magnetic field inhomogeneities cause spins to become out of phase quickly, and distortion and signal dropout become severe [1]. Consequently, single-shot EPI fMRI suffers technical limitations at high field. Here we consider two alternatives to EPI for high field f...
