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 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 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...

Figure 2. (a) ADC (unit 1×10 mm/s) changes in the presence and absence of reperfusion; (b)histogram of tp2 ADC in the reperfused ROI that did (infarct) and did not (noninfarct) go on infarction. The two vertical lines show ADC abnormal threshold (left) and normal mean (right). Figure 1. Representative ADC, MTT at tp1 and tp2 and FLAIR at tp3 from two patients. The range of the colorbar is from ...
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...
