We report a case of heat stroke in which detection of brain injury was improved by high b-value diffusion-weighted imaging (DWI). High b-value DWI revealed moderate to marked hyperintensity at/around bilateral dentate nuclei and part of thalami. Apparent diffusion coefficient maps revealed apparent diffusion coefficient decrease of the dentate lesions. Routine DWI showed only mild hyperintensit...

BACKGROUND AND PURPOSE Time of stroke onset is uncertain for patients who wake from sleep with stroke. Functional imaging techniques may allow estimation of benefit and risk of acute stroke therapy. We compared the clinical and multimodal MRI findings of patients with uncertain stroke onset with those with known onset time. METHODS Patients imaged within 24 hours of ischemic stroke onset betw...

Purpose To enable SWI that is robust to severe head movement. Methods Prospective motion correction using a markerless optical tracker was applied all pulse sequences. Three-dimensional gradient-echo and 3D EPI were used as reference sequences, but expected be sensitive motion-induced B0 changes, the long TE required for allows phase discrepancies accumulate between shots. Therefore, 2D interle...

PURPOSE To compare the added value of dynamic contrast material-enhanced ( CE contrast enhanced ) ( DCE dynamic CE ) magnetic resonance (MR) imaging with that of dynamic susceptibility CE contrast enhanced ( DSC dynamic susceptibility CE ) MR imaging with the combination of CE contrast enhanced T1-weighted imaging and diffusion-weighted ( DW diffusion weighted ) imaging for predicting recurrent...

OBJECTIVE To investigate whether proton density-weighted imaging can detect the "hot cross bun" sign in the pons in multiple system atrophy with predominant cerebellar ataxia significantly better than T2-weighted imaging at 3T. METHODS Sixteen consecutive patients with multiple system atrophy with predominant cerebellar ataxia according to the Consensus Criteria were reviewed. Axial unenhance...

One central purpose of Experimental Philosophy (hereafter, x-phi) is to criticize the alleged reliance on intuitions in contemporary philosophy. In my book Philosophy without Intuitions (hereafter, PWI), I argue that philosophers don’t rely on intuitions. If those arguments are good, experimental philosophy has been engaged in an attack on a strawman. The goal of this paper is to bolster the cr...
