Correlation of Apparent Diffusion Coefficient and Computed Tomography Density in Acute Ischemic Stroke
and Computed Tomography Density in Acute Ischemic Stroke To the Editor: We read with interest the recent article by Kucinski et al.1 The authors observed a decrease in the apparent diffusion coefficient (ADC) in diffusion-weighted MR imaging and a corresponding decrease in CT density in patients suffering from acute ischemic stroke of the anterior cerebral circulation. CT measurements showed a ...
متن کاملCorrelation of apparent diffusion coefficient and computed tomography density in acute ischemic stroke.
BACKGROUND AND PURPOSE Diffusion-weighted MR imaging is very sensitive for the detection of restricted molecular water diffusion in acute ischemic stroke. CT is sensitive to net water uptake in ischemic edema. We compared the decrease in the apparent diffusion coefficient (ADC) in diffusion-weighted MR imaging with CT density changes to study the correlation between diffusion restriction and wa...
متن کاملAssociation of early CT abnormalities, infarct size, and apparent diffusion coefficient reduction in acute ischemic stroke.
BACKGROUND AND PURPOSE Diffusion-weighted (DW) imaging is more sensitive for early ischemia than CT, and apparent diffusion coefficient (ADC) mapping permits quantification of the severity of cytotoxic edema. We examined the relationship between early CT findings, ischemic lesion volume on DW images, and edema subtype. METHODS Patients in whom early signs of ischemia were detected on baseline...
متن کاملRelationship between apparent diffusion coefficient and subsequent hemorrhagic transformation following acute ischemic stroke.
BACKGROUND AND PURPOSE A method for identifying patients at increased risk for developing secondary hemorrhagic transformation (HT) after acute ischemic stroke could be of significant value, particularly in patients being considered for thrombolytic therapy. We hypothesized that diffusion-weighted MRI might aid in the identification of such patients. METHODS We retrospectively analyzed 17 pat...
متن کاملDiffusion-weighted magnetic resonance imaging versus computed tomography in the diagnosis of acute ischemic stroke.
Current treatment protocols using reperfusion therapy for acute ischemic stroke rely on non-contrast computed tomography (NCCT), with most indications including the absence of acute hemorrhage or large volume of infarction in the presence of clinical signs and symptoms. This predictably results in a significant incidence of the administration of reperfusion therapy to patients with "stroke mimi...
