Cedars-Sinai investigators can identify comprehensive cardiovascular risk from CT scans obtained without contrast dye, which some patients cannot tolerate, through the use of AI algorithms. Credit: Cedars-Sinai Medical Center A recent study designed and implemented by investigators at Cedars-Sinai found that artificial intelligence (AI) can accurately evaluate cardiovascular risk during a routine chest computed tomography…
Group comparisons of lnGALP scores in the CoGM and WM, CoT, and normalized brain volume in MS as compared with HC (A–D); in MS patients on H-DMT (HT) as compared with MS patients on low-efficacy or no DMT (LT) and as compared with HC (E–H); and in progressive versus RMS patients in the HT group…
Diagram shows interrelationship of planetary health, climate change, and radiology. GHG = greenhouse gas. Credit: Radiological Society of North America (RSNA) A diverse writing group—lead by authors at the University of Toronto—have developed an approach for radiology departments and practices to reduce their greenhouse gas emissions and become more resilient to the effects of climate…
Looking at an ultrasound image, Shin points to a region of the brain showing strong microbubble activity from a nerve stimulation test. Credit: Elizabeth Bello, Beckman Institute Communications Office Researchers at the Beckman Institute for Advanced Science and Technology have developed a new technique to make ultrasound localization microscopy, an emerging diagnostic tool used for…
Generation of volumetric and 3D-spatial data sets of the complete β-cell distribution across the human pancreas. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-47686-7 Researchers at Umeå University have succeeded in imaging an entire human organ, a pancreas, in microscopic resolution. By staining different cell-types with antibodies and then using optical 3D imaging techniques to study the…
Credit: Pixabay/CC0 Public Domain In an ischemic stroke, an artery in the brain is blocked by blood clots and the brain cells can no longer be supplied with blood as a result. Doctors must therefore act quickly and unblock the artery with the help of catheters. During the so-called mechanical thrombectomy, a lot of data…

Credit: CC0 Public Domain Large language model GPT-4 matched the performance of radiologists in detecting errors in radiology reports, according to research published in Radiology. Errors in radiology reports may occur due to resident-to-attending discrepancies, speech recognition inaccuracies and high workload. Large language models, such as GPT-4, have the potential to enhance the report generation…
Credit: CC0 Public Domain Artificial intelligence has been found to improve the outcome of patients with voice box cancer, which is a step closer to personalized treatment, new research has revealed. Experts at Newcastle University have discovered artificial intelligence software can play a revolutionary role in guiding treatment for voice box cancer. In the first-of-its-kind…
PEM working principle and 3D elastography mechanism. Credit: Communications Biology (2024). DOI: 10.1038/s42003-024-06126-4 Researchers at the University of Nottingham have created an endoscopic device that can 3D image the stiffness of individual biological cells and complex organisms, a discovery that could help doctors discover and treat cancer earlier. In its early stages, cancer cells are,…
