Mechanical Thrombectomy in Patients with Acute Ischemic Stroke and ASPECTS ≤5
This study examined the clinical features, functional outcomes, and prognostic indicators of acute ischemic stroke (AIS) patients who had an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) ≤ 5 and who underwent mechanical thrombectomy (MT).

Alberta Stroke Program Early CT Score Calculation Using the Deep Learning-Based Brain Hemisphere Comparison Algorithm
The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is a promising tool for the evaluation of stroke expansion to determine suitability for reperfusion therapy. The aim of this study was to validate deep learning-based ASPECTS calculation software that utilizes a three-dimensional fully convolutional network-based brain hemisphere comparison algorithm (3D-BHCA).

Hypoperfusion Intensity Ratio is Associated with Stroke Mechanism in Patients Undergoing Mechanical Thrombectomy
Hypoperfusion Intensity Ratio (HIR), defined as Tmax>10s/Tmax>6s on computed tomography perfusion (CTP), and stroke mechanisms have been independently correlated with angiographic collaterals and patient outcomes. Slowly developing atherosclerotic stenosis may foster collateral development, whereas cardioembolic occlusion may occur before collaterals mature. We hypothesized that favorable HIR is associated with large artery atherosclerosis (LAA) stroke mechanism and good clinical outcome.

Recurrent Ischemic Stroke in a Patient with the Trousseau Syndrome Treated with Dabigatran
A 70-year-old man with multiple ischemic strokes was diagnosed with cardiac embolism and treated with dabigatran. Three months later, he suddenly developed vertigo and vomiting. Magnetic resonance imaging, showed recurrent lesions and blood tests revealed hypercoagulability, hypoproteinemia, and elevated cytokeratin 19 fragments that serve as a tumor marker of lung cancer. Chest computed tomography showed there were small nodules in bilateral lungs and swollen mediastinal lymph nodes. A conclusive diagnosis was impossible because the patient declined invasive procedures. We suspected primary lung cancer and diagnosed conco...

Demographic and Clinical Predictors of Leptomeningeal Collaterals in Stroke Patients
Background: Leptomeningeal collaterals improve outcome after stroke, including reduction of hemorrhagic complications after thrombolytic or endovascular therapy, smaller infarct size, and reduction in symptoms at follow-up evaluation. The purpose of this study was to determine the demographic and clinical variables that are associated with a greater degree of cerebral collaterals.Methods: Clinical data of patients presenting with M1 occlusions of the middle cerebral artery (MCA) and associated computed tomography angiography studies after admission from 3 separate institutions were retrospectively compiled (n = 82). Occl...

Clot Characteristics on Computed Tomography and Response to Thrombolysis in Acute Middle Cerebral Artery Stroke
Clinical and computer tomography angiography (CTA) correlates of hyperdense middle cerebral artery sign (HMCAS) and dot sign were revisited in patients treated for acute MCA stroke. Temporal evolution of these signs over 24 hours was assessed quantitatively by density (Hounsfield unit [HU]) measurements.

Contrast-Enhanced Computed Tomography as a Necessary Scan in Acute Stroke: A Case Series
We present a number of exemplary cases where the diagnostic value of the contrast-enhanced computed tomography (CT) after CT angiography in our acute stroke imaging protocol was of fundamental clinical significance.

Multidisciplinary Protocol for Rapid Head Computed Tomography Turnaround Time in Acute Stroke Patients
The door-to-computed tomography (CT) head reporting time is an essential step to determining eligibility for thrombolysis in acute stroke patients, but the specific components of the process have not been reported in detail.

Auditory Spatial Deficits in the Early Stage of Ischemic Cerebral Stroke
Clinical research, together with computed tomography/magnetic resonance imaging findings, proves that ischemic stroke (IS) that damages auditory pathways can cause hearing loss and impairment of higher auditory processes such as sound localization. The goal of the study was to find possible correlations between the IS risk factors, ischemic lesion volume and localization, neurologic status, and the sound localization capability in acute IS patients.

Inter-rater Agreement in Three Perfusion-Computed Tomography Evaluation Methods before Endovascular Therapy for Acute Ischemic Stroke
There is ongoing debate on which method of perfusion computed tomography (PCT) evaluation in ischemic stroke is the most appropriate for improved selection of patients for endovascular treatment. We sought to test different assessment methods for inter-rater reliability.

Good Clinical and Radiological Correlation from Standard Perfusion Computed Tomography Accurately Identifies Salvageable Tissue in Ischemic Stroke
It has been debated whether the penumbral pattern, as identified using multimodal imaging, is a specific marker of tissue viability in ischemic stroke. We assessed whether perfusion computed tomography (PCT) accurately identifies salvageable tissue and helps predict postreperfusion outcomes.

Relative Mean Transit Time Predicts Subsequent Stroke in Symptomatic Carotid Occlusion
Mean transit time (MTT) measurements to assess cerebral hemodynamics are easily obtained by computed tomography and magnetic resonance imaging. We reviewed hemodynamic and clinical outcome data from the St. Louis Carotid Occlusion Study to determine if increased MTT was associated with an increased risk of stroke in patients with symptomatic complete carotid artery occlusion.
