Na ïve bayes classifier assisted automated detection of cerebral microbleeds in SWI brain images
Biochem Cell Biol. 2023 Aug 28. doi: 10.1139/bcb-2023-0156. Online ahead of print.ABSTRACTCerebral Microbleeds (CMBs) in the brain are the essential indicators of critical brain disorders such as dementia and ischemic stroke. Generally, CMBs are detected manually by experts which is an exhaustive task with limited productivity. Since, CMBs have complex morphological nature, so manual detection is prone to errors. This paper presents a machine learning-based automated Cerebral Microbleeds detection technique in the brain SWI scans based on statistical feature extraction and classification. The proposed method consists of th...

E-223 Improved time to diagnosis with portable MR imaging
ConclusionPortable MRI is a promising innovation with the aim to expand patient access and improve diagnostic times so that critical and potential lifesaving imaging diagnoses can be promptly treated with the urgency that is required. While initial analysis provides evidence that portable MRI has advantages over conventional MRI systems including workflow efficiency and improved patient imaging times, this will need to be compared to the unfortunate negative drawbacks of lessened image resolution and limited imaging sequences that come with the convenience of portable MRI systems. If the hypothesis is further corroborated,...

Development of predictive algorithms for the wear resistance of denture teeth materials
CONCLUSIONS: 3D printed denture teeth materials showed the lowest wear out of all studied for 48 months simulation. LSTM model was successfully developed to predict wear of various denture teeth. The developed LSTM model has the potential to reduce simulation duration and specimen number for wear testing of various dental materials, while potentially improving the accuracy and reliability of wear testing predictions. This work paves the way for generalized multi-sample models enhanced with empirical information.PMID:37392604 | DOI:10.1016/j.jmbbm.2023.105984

Scientists use AI to decipher words and sentences from brain scans
A technique based on artificial intelligence (AI) can translate brain scans into words and sentences, a team of computational neuroscientists reports. Although in the early stages and far from perfect, the new technology might eventually help individuals with brain injuries or paralysis regain the ability to communicate, researchers say. The study “shows that, using the right methods and better models, we can actually decode what the subject is thinking,” says Martin Schrimpf, a computational neuroscientist at the Massachusetts Institute of Technology who was not involved in the work. Other research teams hav...

Inflammation May Be the Culprit Behind Our Deadliest Diseases
In the early days of my medical residency, I met a man whom we’ll call Jason. He arrived to our emergency room on a holiday, nonchalant yet amiable, and complained of mild chest pain. Jason was tall and trim, with a strong South Boston accent and fingertips still faintly stained from his last home-improvement project. He was only 45 years old, but he looked much younger. He didn’t smoke, barely drank alcohol, and his cholesterol levels had always been normal. No one in his family had a history of heart disease. He asked us if we could work quickly—he wanted to be home for dinner with his daughters. [time-...

The Danish landscape of providing support for caregivers of people with potentially life-threatening disease: A cross-sectional study among representatives of health services in Danish municipalities and hospitals
CONCLUSIONS: Disparities and significant differences across diagnoses exist in the identification of caregivers and the provision of support initiatives. Support initiatives involving caregivers primarily targeted patients. Future studies should investigate how caregivers' needs can be met across different diagnoses and healthcare settings and investigate potential changes in caregivers' needs during disease trajectories. In clinical practice, identification of vulnerable caregivers should be a major focus, and disease-specific clinical guidelines may be required to ensure sufficient support for caregivers.PMID:37026179 | ...

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...

Bifurcation matching for consistent cerebral vessel labeling in CTA of stroke patients
ConclusionFormulating the vessel labeling process as a maximization task for bifurcation matching can vastly improve accurate vessel tracing. The proposed algorithm only uses simple features and does not require expensive training data.
