Study design and brief results of this study. Credit: Science China Press In a 3-stage study, three cohorts were used for diagnostic performance, and prognostic performance evaluation for this fully automated, one-click, on-site CT-FFR technique. The study was led by Professors Long Jiang Zhang and Guang Ming Lu (Department of Radiology, Jinling Hospital, Affiliated Hospital…
A case of active serpiginous choroiditis on color fundus photography (CFP), short-wavelength blue-light autofluorescence (swBAF, 450 nm), long-wavelength blue-light autofluorescence (lwBAF, 488 nm), green-light autofluorescence (GAF, 518 nm), and infrared-light autofluorescence (IRAF, 787 nm). Inactive lesions are completely hypoautofluorescent on FAF modalities, while active lesion borders depict a speckled pattern of hyper- and hypoautofluorescence. Credit:…
A team of MIT researchers found highly memorable images have stronger and sustained responses in ventro-occipital brain cortices, peaking at around 300ms. Conceptually similar but easily forgettable images quickly fade away. Credit: Alex Shipps/MIT CSAIL For nearly a decade, a team of MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) researchers have been seeking to…
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…
