Predictors of Good Outcome After Endovascular Treatment for Patients with Vertebrobasilar Artery Occlusion due to Intracranial Atherosclerotic Stenosis
AbstractPurposeTo investigate the predictors for good outcome of endovascular therapy (EVT) for patients with acute vertebrobasilar artery occlusion (VBAO) due to intracranial atherosclerosis stenosis (ICAS).MethodsFrom April 2012 to February 2018, patients with VBAO due to ICAS who received EVT were retrospectively analyzed. ICAS was defined as fixed stenosis of>70%, or a degree of fixed stenosis>50% in addition to either perfusion impairment or evidence to re-occlusion. Good outcome was defined as mRS ≤2 at 90 days. Both logistic regression and receiver operating characteristic curve (ROC) analyses were performe...

Spot Sign in Secondary Intraventricular Hemorrhage Predicts Early Neurological Decline
AbstractPurposeThe spot sign is associated with intracerebral hemorrhage (ICH) expansion and neurological decline. However, the relationship of the spot sign to secondary intraventricular hemorrhage (IVH) has not been well established. The presence of the spot sign in secondary IVH may provide information regarding neurologic outcome in a population with known poor prognosis.MethodsA subset analysis was performed of patients with IVH from the Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 (ATACH-II) study, a randomized clinical trial examining the effect of intensive blood pressure reduction on hematoma expansio...

Role of Diffusion Tensor Imaging Parameters in the Characterization and Differentiation of Infiltrating and Non-Infiltrating Spinal Cord Tumors
AbstractBackground and PurposeRecent attempts to utilize diffusion tensor imaging (DTI) to identify the extent of microinfiltration of a  tumor in the brain have been successful. It was therefore speculated that this technique could also be useful in the spinal cord. The aim of this study was to differentiate between infiltrating and noninfiltrating intramedullary spinal tumors using DTI-derived metrics.Material and MethodsThe study group consisted of 6  patients with infiltrating and 12 with noninfiltrating spinal cord tumors. Conventional magnetic resonance imaging (MRI) with gadolinium administration was ...

Imaging Clot Characteristics in Stroke and its Possible Implication on Treatment
AbstractIschemic cerebral stroke is an increasingly treatable entity due to the recent developments in intravascular clot extraction, with recent research indicating that the efficacy of the chosen thrombectomy device may be affected by the composition of the occluding clot. This literature review summarizes the results from analytical clot imaging studies, and in vitro and in vivo thrombectomies, to assess whether the choice of thrombectomy device can be optimized to the composition of the occluding clot. The literature has shown that the composition of the clot impacts its mechanical properties and interactions with the ...
