Objective The objective of this study was to investigate the frequency of hippocampal sulcus remnants (HSRs) in nonelderly adults using ultra-high-resolution 7T magnetic resonance (MR) images and their imaging features. Methods A total of 33 healthy

Background and Purpose— We aimed to examine perfusion changes between 3 and 6 and 6 and 24 hours after stroke onset and their impact on tissue outcome. Methods— Acute ischemic stroke patients underwent perfusion magnetic resonance imaging at 3, 6

Background and Purpose— Alterations of cerebral glucose metabolism are well anticipated during cerebral ischemia. However, detailed spatiotemporal characteristics of disturbed cerebral glucose metabolism during acute ischemia remain largely elusive

Introduction: Collateral flow is postulated to play an important role in maintaining tissue viability during acute ischemic stroke (AIS), but its direct influence on the ischemic penumbra and eventual tissue outcome is not well understood. Hypothesis

Introduction: CSF volumetric change within the first 24hrs after ischemic stroke (ΔCSF) may be an early imaging biomarker of cerebral edema. The ability to accurately and rapidly quantify ΔCSF in large multicenter stroke populations will facilitate

Background and Purpose— Statin pretreatment has been associated with improved outcomes in patients with ischemic stroke. Although several mechanisms have been examined in animal models, few have been examined in patients. We hypothesized that patie

Background and Purpose— This study aimed to examine the temporal relationship between tissue perfusion and apparent diffusion coefficient (ADC) changes within 6 hours of ischemic stroke onset and how different reperfusion patterns may affect tissue

Background and Purpose— A noninvasive MRI method to measure cerebral oxygen metabolism has the potential to assess tissue viability during cerebral ischemia. The purposes of this study were to validate MR oxygenation measurements across a wide rang

Stroke. 46
Background: During the first 24 hours after stroke, brain perfusion is highly dynamic. While early reperfusion can salvage tissue, it is unclear if late perfusion changes affect tissue fate. We examined perfusion changes between 6 and 24h after strok

Background: Human Immunodeficiency Virus (HIV) infected individuals are at high risk for ischemic stroke. Magnetic resonance imaging (MRI) method of measurement of cerebral blood flow (CBF) and oxygen extraction fraction (OEF) may help assess the str
