Evaluation of the clinical-diffusion and perfusion-diffusion mismatch models in DEFUSE.
BACKGROUND AND PURPOSE The perfusion-diffusion mismatch (PDM) model has been proposed as a tool to select acute stroke patients who are most likely to benefit from reperfusion therapy. The clinical-diffusion mismatch (CDM) model is an alternative method that is technically less challenging because it does not require perfusion-weighted imaging. This study is an evaluation of these 2 models in t...
متن کاملMismatch and defuse: harvesting the riches of multicenter neuroimaging-based stroke studies.
See related article, pages 1826–1830. The goal of acute stroke evaluation is to determine not only stroke type (ischemic versus hemorrhagic) and localization (anatomical and vascular), but perhaps more importantly, to determine reversibility (presence of an ischemic penumbra that may be salvaged with acute therapy). Traditionally, neurologists have relied on history and neurological examination...
متن کاملTeacher Cognition and Personal Beliefs: A Harmonious Mismatch?
Some engravings are meant to be adored and some possibly abhorred. Teacher cognition, as a meant-to-be-praised engraving, is defined by Borg (2003, p. 81) as “the unobservable cognitive dimension of teaching what teachers know, believe, and think.” This concept in teaching has recently gained momentum meaning that teachers learn so much about their teaching through the vast experience they have...
متن کاملResolving Goodman’s Paradox How to Defuse Inductive Skepticism
Subjective Bayesian inference is unsuitable as an ideal for learning strategies to approximate, as the arbitrariness in prior probabilities makes claims to Bayesian learning too easily vulnerable to inductive skepticism. An objective Bayesian approach, which determines priors by maximizing information entropy, runs into insurmountable difficulties in conditions where no definite background theo...
متن کاملA topographic study of the evolution of the MR DWI/PWI mismatch pattern and its clinical impact: a study by the EPITHET and DEFUSE Investigators.
BACKGROUND AND PURPOSE The ischemic penumbra may be classical, with complete annular configuration around the infarct core, or nonclassical with a more fragmented pattern. We tested the hypotheses that these penumbral patterns may: be associated with specific predictive factors, influence infarct growth and clinical outcome, and influence the effect of tissue plasminogen activator (t-PA). MET...
