What Are the Classifications of Perinatal Stroke?
Discussion Perinatal stroke occurs in about 1:1000 live births and is a “focal vascular injury from the fetal period to 28 days postnatal age.” Perinatal stroke is the most common cause of hemiparetic cerebral palsy and causes other significant morbidity including cognitive deficits, learning disabilities, motor problems, sensory problems including visual and hearing disorders, epilepsy, and behavioral and psychological problems. Family members are also affected because of the potential anxiety and guilt feelings that having a child with a stroke presents, along with the care that may be needed over the child&#...

Using convolutional neural network to analyze brain MRI images for predicting functional outcomes of stroke
AbstractNowadays, the physicians usually predict functional outcomes of stroke based on clinical experiences and big data, so we wish to develop a model to accurately identify imaging features for predicting functional outcomes of stroke patients. Using magnetic resonance imaging of ischemic and hemorrhagic stroke patients, we developed and trained a VGG-16 convolutional neural network (CNN) to predict functional outcomes after 28-day hospitalization. A total of 44 individuals (24 men and 20 women) were recruited from Taoyuan General Hospital and China Medical University Hsinchu Hospital to enroll in the study. Based on â€...

Machine Learning-Based Model for Prediction of Hemorrhage Transformation in Acute Ischemic Stroke After Alteplase
In this study, an RF machine learning method was successfully established to predict HT in AIS patients after intravenous alteplase, which the sensitivity was 66.7%, and the specificity was 80.7%.

Prediction of Hemorrhagic Transformation Severity in Acute Stroke From Source Perfusion MRI
Conclusion: The key contribution of our framework formalize HT prediction as a machine learning problem. Specifically, the model learns to extract imaging markers of HT directly from source PWI images rather than from pre-established metrics. Significance: Predictions visualized in terms of spatial likelihood of HT in various territories of the brain were evaluated against follow-up gradient recalled echo and provide novel insights for neurointerventionalists prior to endovascular therapy.

Natural Language Processing of Radiology Reports to Detect Complications of Ischemic Stroke
ConclusionsOur study demonstrates robust performance and external validity of a core NLP tool kit for identifying both categorical and continuous outcomes of ischemic stroke from unstructured radiographic text data. Medically tailored NLP methods have multiple important big data applications, including scalable electronic phenotyping, augmentation of clinical risk prediction models, and facilitation of automatic alert systems in the hospital setting.

MRI for all: Cheap portable scanners aim to revolutionize medical imaging
.news-article__hero--featured .parallax__element{ object-position: 47% 50%; -o-object-position: 47% 50%; } The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing. The cylind...

Korean JLK Inspection launches AI-powered imaging diag system
Korean JLK Inspection said yesterday that it launched its AIHub artificial intelligence-powered medical image diagnostics platform. The newly launched AIHub system is designed to analyze images from a number of different imaging modalities, including magnetic resonance imaging, computed tomography, X-ray and mammography, the Seoul-based company said. JLK Inspection claims the system can detect and monitor for more than 30 medical conditions in 14 regions of the body. The company added that the system is focused on brain diseases and conditions including ischemic stroke, hemorrhagic stroke, brain aneurysm and Alzheimer̵...

What Causes Hyperammonemia?
Discussion Reye’s syndrome (RS)is named for Dr. Douglas Reye who along with Drs. G. Morgan and J. Baral described encephalopathy and fatty accumulation and degeneration in children in a 1963 Lancet article. RS usually affects children but can occur at all ages. All organs can be affected but the liver and brain are primarily affected causing liver failure and encephalopathy as toxic metabolites (especially ammonia) accumulate, and intracranial hypertension and cerebral edema occurs. As the ammonia levels begin to rise (> 100 mg/dL) patients lose their appetite, have nausea and emesis and mental status changes whic...

Deep Learning-Based Approach for the Diagnosis of Moyamoya Disease
Moyamoya disease is a unique cerebrovascular disorder that is characterized by chronic progressive bilateral stenosis of the terminal portion of the internal carotid arteries (ICAs), and it is associated with the formation of an abnormal vascular network at the base of the brain.1,2 For the diagnosis of the moyamoya disease, digital subtraction angiography (DSA), which helps evaluate collateral circulation from the view point of the hemorrhagic risk, is the gold standard.3,4 On the contrary, magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) can be used as alternatives to conventional angiography bec...

Is This Primary Exertional Headache?
Discussion Commonly occurring primary headaches include tension, cluster and migraine headaches. “Other primary headaches” are often situational. Patients can have more than 1 type of these “other” headaches along with more common headaches. Other primary headaches as a group tend to be self-limited with long remission periods. Some other primary headaches include: Thunderclap headache Explosive sudden onset with maximum intensity in less 1 minute and resolution within 5 minutes usually 43/100,000 persons in adults Primary or secondary Secondary causes include intracranial hemorrhage, stroke, thro...
