The Course of Apparent Diffusion Coefficient Values following Perinatal Arterial Ischemic Stroke
BACKGROUND Diffusion weighted MR imaging (DWI) plays an important role in the diagnosis of perinatal arterial ischemic stroke (PAIS) during the acute phase. Its derived apparent diffusion coefficient (ADC) can be used to quantify the diffusion restriction. Aim of the current study was to identify the changes in ADC values in the acute phase following PAIS. METHODS A cohort of 36 infants with ...
متن کاملNeurite beading is sufficient to decrease the apparent diffusion coefficient after ischemic stroke.
Diffusion-weighted MRI (DWI) is a sensitive and reliable marker of cerebral ischemia. Within minutes of an ischemic event in the brain, the microscopic motion of water molecules measured with DWI, termed the apparent diffusion coefficient (ADC), decreases within the infarcted region. However, although the change is related to cell swelling, the precise pathological mechanism remains elusive. We...
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 کاملCorrelation 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 ...
