Relevance of the cerebral collateral circulation in ischaemic stroke: time is brain, but collaterals set the pace.
Abstract Blood supply to the brain is secured by an extensive collateral circulation system, which can be divided into primary routes, i.e., the Circle of Willis, and secondary routes, e.g., collaterals from the external to the internal carotid artery and leptomeningeal collaterals. Collateral flow is the basis for acute stroke treatment, since neurones will only survive long enough to be rescued with reperfusion therapies if there is sufficient collateral flow. Poor collateral flow is associated with worse outcome and faster growth of larger infarcts in acute stroke treatment. Therapeutic promotion of collateral ...

How one ED uses telemedicine in the ambulance
When you think of telemedicine, what comes to mind? Often the answer is a split screen—physician and patient in separate locations on their computers or tablets. But one health system has shown the true breadth of telemedicine’s reach by using the technology to treat patients during the critical early moments of a stroke. Find out how. The risk of damage and disability in patients who are experiencing a stroke increases with any delay in care delivery. Two emergency physicians at the University of Virginia (UVA) Health System understood the need for speed when it comes to caring for patients in the midst of acute str...

Impact of Asynchronous Training on Radiology Learning Curve among Emergency Medicine Residents and Clerkship Students.
CONCLUSION: Incorporating asynchronous WBL modules into EM clerkship and residency curriculum provides early radiographic exposure in their clinical training and can enhance diagnostic head CT scan interpretation. PMID: 29272248 [PubMed - in process]

OA214 An experience with open source machine learning software deepmedic
The aim of this study was to investigate if 3D convolutional deep neural network implementation DeepMedic [1] could be applied to computed tomography angiography (CTA) images in acute stroke lesion detection. DeepMedic has previously been successful in lesion segmentation from magnetic resonance images [2].

Deep learning algorithms for detection of critical findings in head CT scans: a retrospective study
Publication date: Available online 11 October 2018Source: The LancetAuthor(s): Sasank Chilamkurthy, Rohit Ghosh, Swetha Tanamala, Mustafa Biviji, Norbert G Campeau, Vasantha Kumar Venugopal, Vidur Mahajan, Pooja Rao, Prashant WarierSummaryBackgroundNon-contrast head CT scan is the current standard for initial imaging of patients with head trauma or stroke symptoms. We aimed to develop and validate a set of deep learning algorithms for automated detection of the following key findings from these scans: intracranial haemorrhage and its types (ie, intraparenchymal, intraventricular, subdural, extradural, and subarachnoid); ca...

Improvement of diagnostic performance of hyperacute ischemic stroke in head CT using an image-based noise reduction technique with non-black-boxed process
To date, a variety of image-based noise reduction (INR) techniques for computed tomography (CT) have been reported. They are based on iterative processes or deep learning techniques. Some INR products using iterative processes are already commercially available and have been reported to exhibit noise reduction performance better than hybrid-type iterative reconstruction (HIR) in abdominal CT [1,2]. However, the details of the processes inside these commercial INR systems are usually proprietary and cannot be readily replicated outside.
