Methods: We made use of Cochrane Library, PubMed, and Embase in order to obtain
literature and papers. The combination analysis of both direct and indirect evidence in terms …

Background This study aimed to identify and validate whole brain perfusion computed
tomography (CTP) thresholds for ischemic core and salvageable penumbra in acute stroke …

Stroke mimics account for up to a third of suspected strokes. The main causes are epileptic
deficit, migraine aura, hypoglycemia, and functional disorders. Accurate recognition of stroke …

Relative delays in blood-oxygen-level-dependent (BOLD) signal oscillations can be used to
assess cerebral perfusion without using contrast agents. However, little is currently known …

Background and purpose To investigate the relation between DWI-PWI mismatch and FLAIR-
hyperintense vessel (FHV) sign and their influence on the prediction of the infarct growth in …

We aimed to investigate the clinicoradiologic determinants of negative diffusion-weighted
image (DWI) results in patients with acute cerebral infarction (ACI). The medical records …

Background and purpose Multiple hypointense vessels (MHV) on susceptibility-weighted
imaging (SWI) is associated with an increased oxygen demand in acute cerebral ischemia …

Background Few studies with a limited number of patients focused on the outcomes of
patients with diffusion-weighted imaging (DWI)-negative acute ischemic stroke (AIS) after …

Because of its excellent sensitivity and specificity to diagnose arterial ischemic stroke (AIS)
in the acute phase, MRI answers the main questions to guide treatment in “candidates” for …

Objective: We longitudinally assessed patients presenting with total mismatch and
hypothesized that hypoperfusion intensity ratio (HIR), severity of stroke, and occlusion of …
