recommendations! Published in 2017 at "JAMA Neurology"

DOI: 10.1001/jamaneurol.2016.4491

Abstract: Importance Robust collateral blood vessels have been associated with better neurologic outcome following acute ischemic stroke (AIS). The most commonly used methods for identifying collaterals are contrast-based angiographic imaging techniques, which are not possible in… read more here.

DOI: 10.1002/acn3.70263

Abstract: OBJECTIVE Myotonic dystrophy type 2 (proximal myotonic myopathy, PROMM) is a progressive multisystem disorder with muscular symptoms (proximal weakness, pain, myotonia) and systemic manifestations such as diabetes mellitus, cataracts, and cardiac arrhythmias. A hallmark feature… read more here.

DOI: 10.1002/brb3.792

Abstract: The accurate diagnosis and monitoring of idiopathic Parkinson disease (PD), a progressive neurodegenerative disorder, has not been fully developed. This study sought to identify a neurochemical profile in multiple regions of the PD brain and… read more here.

DOI: 10.1002/hbm.23642

Abstract: Gamma‐aminobutyric acid (GABA) and glutamate are believed to have inhibitory and exhibitory neuromodulatory effects that regulate the brain's response to sensory perception. Furthermore, frequency‐specific synchronization of neuronal excitability within the gamma band (30–80 Hz) is… read more here.

DOI: 10.1002/jmri.29690

Abstract: Edited MRS technique such as MEshcher‐GArwood Point RESolved Spectroscopy (MEGA‐PRESS) can determine isocitrate dehydrogenase mutation (IDH) mutation status in patients with gliomas but its accuracy in assessing glioma grade has not yet been formally evaluated. read more here.

DOI: 10.1002/jmv.70250

Abstract: A large spectrum of viruses can infect the male reproductive system (MRS). Although the MRS adopts the local antiviral defense, it has also been considered as a potential viral reservoir. We hypothesize that tissue‐specific cells… read more here.

Estimation and removal of spurious echo artifacts in single‐voxel MRS using sensitivity encoding

Sign Up to like & get
recommendations! Published in 2021 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.28848

Abstract: In localized MRS, spurious echo artifacts commonly occur when unsuppressed signal outside the volume of interest is excited and refocused. In the spectral domain, these signals often overlap with metabolite resonances and hinder accurate quantification.… read more here.

DOI: 10.1002/mrm.29222

Abstract: Single‐voxel MRS (SV MRS) requires robust volume localization as well as optimized crusher and phase‐cycling schemes to reduce artifacts arising from signal outside the volume of interest. However, due to local magnetic field gradients (B0… read more here.
