...Nobuyuki Izutsu; Yasunori Fujimoto; Naoaki Yamada; Ryuichiro Kajikawa; Kazuhiro Yoshimura; Munenori Nagashima; Akatsuki Wakayama; Toshiki Yoshimine Background/Aim: We previously observed spotty hyperintense lesions in the region of the perforating arteries on peri-ictal diffusion-weighted imaging...

...Angelika Alonso; Kristina Szabo; Marc E. Wolf; Anne D. Ebert; Martin Griebe; Michael G. Hennerici; Achim Gass Background: Acute stroke syndromes with negative diffusion-weighted imaging (DWI) but extensive perfusion deficits are rare and constitute a diagnostic challenge due to different...

...-lasting worsening of the poststroke sequelae may develop, but the underlying mechanism of deficit worsening has not been systematically studied by magnetic resonance diffusion-weighted imaging (MRI-DWI). Methods: From 2008 to 2009, 1,010 ischemic stroke patients were admitted to our stroke unit at the Ege...

...Naoki Oyama; Hiroshi Moriwaki; Naoaki Yamada; Kazuyuki Nagatsuka; Hiroaki Naritomi Background: Various mechanisms can be considered in ischemic stroke with internal carotid artery (ICA) occlusive diseases. We clarified the etiologic mechanisms from lesion patterns on diffusion-weighted imaging (DWI...

... other tools than MRI predicting tissue infarction would be valuable. We hypothesized that ABCD 2 risk score is a valid screening tool for diffusion-weighted imaging (DWI) lesions. Methods: TIA patients were prospectively enrolled in an observational MRI study to receive acute and follow-up stroke MRI...

.... We aimed to identify predictors for progressive neurological deficits using diffusion-weighted imaging (DWI). Methods: We studied 40 consecutive patients who were classified into two groups based on their NIHSS scores: progressive infarction (PI) and non-progressive infarction (NPI). We calculated...

...Shin Ahn; Won Kim; Yoon-Seon Lee; Won Young Kim; Jae Ho Lee; Bum Jin Oh; Kyoung Soo Lim Background/Aims: Hippocampal lesions on diffusion-weighted imaging (DWI) are commonly described in transient global amnesia (TGA). We evaluated the utility of DWI and the presence of hippocampal lesions...

... on diffusion-weighted imaging (DWI). Methods: From January 2006 to October 2010, we retrospectively enrolled 21 acute infarct patients with bilateral high-grade ICA stenosis. The infarct patterns were divided into territory, cortical border-zone and internal border-zone by DWI. Results: The milder ICA stenosis...

... was to evaluate the diagnostic value of diffusion-weighted imaging (DWI) in the post-acute phase of cerebral ischemia in patients in whom CT did not yield a definitive diagnosis. Methods: We retrospectively evaluated DWI findings in 214 patients, out of a series of 1,680 patients admitted to our hospital...

...Thorleif Etgen; Helga Gräfin von Einsiedel; Michael Röttinger; Kerstin Winbeck; Bastian Conrad; Dirk Sander Even using diffusion-weighted images (DWI) detection of acute brainstem infarction (BI) is still a challenge. To evaluate the clinical efficacy of a DWI protocol with improved spatial...
