Hyperacute ischemic stroke missed by diffusion-weighted imaging.

چکیده
We present two cases of hyperacute ischemic stroke that were initially missed by diffusion-weighted imaging; abnormalities in locations corresponding to focal neurologic deficits were discovered by MR angiography and perfusion-weighted imaging. Within hours, follow-up diffusion-weighted scans revealed partial conversion of the hypoperfused regions to complete stroke. These cases illustrate the potential for a nonresolving stroke-in-evolution to go undetected by diffusion-weighted imaging at hyperacute timepoints.

Hyperacute ischemic stroke without lesions on diffusion-weighted imaging in a patient treated with rtPA thrombolysis
KEY CLINICAL MESSAGE We report a comatose patient with severe neurological deficits who was without spontaneous language or movement. He had a good response to recombinant tissue plasminogen activator (rtPA) thrombolysis even though there were no detectable lesions on diffusion-weighted imaging (DWI). DWI is very sensitive for diagnosing hyperacute ischemic stroke, and rtPA thrombolysis is the ...
متن کاملMetabolic counterpart of decreased apparent diffusion coefficient during hyperacute ischemic stroke: a brain proton magnetic resonance spectroscopic imaging study.
BACKGROUND AND PURPOSE Recent studies have shown that the brain ischemic area defined by the map of decreased apparent diffusion coefficient (ADC) obtained by diffusion-weighted imaging (DWI) during the first hours of ischemic stroke includes a significant part of ischemic penumbra. We hypothesize that the misjudgment of the final infarct size by ADC mapping may be related to a restricted abili...
متن کاملDiffusion kurtosis is sensitive to hyperacute cerebral ischemia and increases with ischemic progression without renormalization
Introduction The outcome of stroke treatment relies in large part on reliable staging of ischemic tissue, and it remains a challenge to find the optimal MR techniques as such. Owing to the high sensitivity and specificity of conventional MR diffusion-weighted imaging in ischemic tissue delineation, additional clinically relevant information regarding ischemic tissue microstructure can be probed...
متن کاملEarly metabolic changes following ischemia onset in rats: An in vivo diffusion-weighted imaging and 1H-magnetic resonance spectroscopy study at 7.0 T
Despite improvements in imaging techniques, it remains challenging to quantitatively assess the time of ischemic onset of an acute ischemic stroke. It is crucial to evaluate the early signs of infarction, which are predictive of responses to recombinant tissue plasminogen activator within a treatment window of 4.5 h after stroke induction. The aim of the present study was to assess and quantify...
متن کاملA standardized MRI stroke protocol: comparison with CT in hyperacute intracerebral hemorrhage.
BACKGROUND AND PURPOSE Diagnostic imaging in hyperacute ischemic stroke has been revolutionized by the introduction of diffusion- and perfusion-weighted MRI (DWI and PWI). CT, however, is still needed to exclude intracerebral hemorrhage (ICH). The purpose of our study was to determine the diagnostic accuracy of a standardized, multimodal MRI (mMRI) stroke protocol in the qualitative and quantit...
