Analyzing Circle of Willis blood flow in ischemic stroke patients through 3D Stroke Arterial Flow Estimation.
Conclusions We present SAFE analysis for collecting detailed time-resolved cerebral arterial flow data in the entire Circle of Willis for IS. Further study with more cases may be important to test the clinical utilization of SAFE and helpful to the study of the underlying hemodynamics of stroke.

Carotid Bulb Webs as a Cause of "Cryptogenic" Ischemic Stroke EXTRACRANIAL VASCULAR
CONCLUSIONS: Carotid webs exhibit a strong association with ischemic stroke, and their presence should be suspected in patients lacking other risk factors, particularly African American women.

Transfer of stroke patients impairs eligibility for endovascular stroke treatment
Conclusions EST should be provided directly whenever possible as one in four transferred stroke patients becomes ineligible for EST during transfer. If direct transfer is not possible, indication for EST should be re-assessed after transfer.

Variability of Stroke Patients Meeting Endovascular Stroke Trial Criteria in a Non-Clinical Trial Setting
Conclusions The proportion of patients with acute stroke and large vessel occlusion presenting within eight hours that would meet radiological criteria for endovascular stroke trials varies considerably (62-100%) in a cohort outside of clinical trials from an academic comprehensive stroke center. Thus, the radiological criteria used for candidate selection in daily practice will greatly influence the proportion of patients treated with endovascular therapy.

Effects of chronic flexed wrist posture on the elasticity and crosssectional area of the median nerve at the carpal tunnel among chronic stroke patients.
CONCLUSIONS: These results suggest that chronic flexed wrist posture may cause atrophy of the median nerve due to chronic compression after stroke and increase in the stiffness of the median nerve. PMID: 29400371 [PubMed - in process]

Abnormal functional corticomuscular coupling after stroke
Publication date: Available online 4 April 2018 Source:NeuroImage: Clinical Author(s): Xiaoling Chen, Ping Xie, Yuanyuan Zhang, Yuling Chen, Shengcui Cheng, Litai Zhang Motor dysfunction is a major consequence after stroke and it is generally believed that the loss of motor ability is caused by the impairments in neural network that controls movement. To explore the abnormal mechanisms how the brain controls shoulder abduction and elbow flexion in “flexion synergy” following stroke, we used the functional corticomuscular coupling (FCMC) between the brain and the muscles as a tool to identify the temporal evolution of ...

The Yellow Scale Is Superior to the Gray Scale for Detecting Acute Ischemic Stroke on a Monitor Display in Computed Tomography
Conclusions The detection of acute ischemic stroke is improved by changing the display monitor from the gray scale to the yellow scale. From the perspective of color psychology, yellow is associated with higher arousal, cheerfulness, confidence, creativity, and excitement. Therefore, the yellow scale may be suitable for a medical imaging display.

Procedural and clinical outcomes of endovascular recanalization therapy in patients with cancer-related stroke.
Conclusions Although clinical outcomes at discharge were similar for CE and LAA patients, complete recanalization seemed more difficult to achieve in CRS patients than in conventional stroke patients. PMID: 29792090 [PubMed - as supplied by publisher]

Ischemic stroke enhancement using a variational model and the expectation maximization method
ConclusionThese results show the importance of a computational tool to assist neuroradiology decisions, especially in critical situations such as the diagnosis of ischemic stroke.Key Points• Diagnosing patients with stroke requires high efficiency to avoid irreversible cerebral damage.• A computational algorithm was proposed to enhance the visual perception of stroke.• Observers’ performance was increased with the aid of enhanced images.
