CAC score may predict heart attack, stroke risk
Coronary artery calcium (CAC) scoring with CT could determine whether patients with heart disease symptoms are at low risk of heart attacks or strokes, according to a study published March 5 in Radiology.
The study results could help patients with stable chest pain avoid invasive coronary angiography (ICA), said senior author Marc Dewey, MD, of Charité - Universitätsmedizin Berlin in Germany in a statement released by the RSNA.
"[Our] findings suggest that patients with stable chest pain and a coronary artery calcium score of zero may not require invasive coronary angiography using cardiac catheterization because the r...

‘Doing something for the real world’: how 1,000 UK schoolkids helped crack a crystals conundrum
When citizen science in school labs ended up in a particle accelerator, the results advanced our understanding of how crystals form – with a positive impact on the future of medicine, materials science and moreGry Christensen was a 15-year-old year 11 student when she took part in a “citizen science” project to understand how the different crystals in mussel shells form. But unlike most school experiments, the samples that she and her 1,000 fellow secondary school pupils prepared were then blasted by scientists in a particle accelerator using X-rays 10bn times brighter than the sun.“It was a bit of an eye opener,...

Singapore to Build World ’s Largest Facility to Boost Carbon-Removal Power of the Ocean
The Equatic Process, a novel carbon removal technology and one of the best inventions of 2023, is getting a major scale-up, with the world’s largest ocean carbon dioxide removal (OCDR) facility set to be built in Singapore and operational by 2025—sparking optimism for what has been hailed as a potential game changer for global climate efforts after scientists agreed in 2022 that atmospheric carbon-removal technology will be necessary for the world to reach its climate goals.

PCCT improves assessment of coronary artery disease
Ultrahigh-spatial-resolution photon-counting detector CT (PCCT) improves the evaluation of coronary artery disease (CAD) -- enabling the reclassification of disease to a lower category in 54% of patients, researchers have found.
The technology could improve patient management and reduce unnecessary interventions, according to a team that included corresponding author Tilman Emrich, MD, of the Medical University of South Carolina in Charleston. The findings were published February 20 in Radiology.
"Our study provides a glimpse into the potential impact of performing coronary CT angiography [CCTA] using ultrahigh spatial r...

Mysterious ‘comb’ drawings may be among oldest cave paintings in South America
The soaring stone walls of Argentina’s Huenul Cave, a 630-meter-square rock shelter in northern Patagonia, are covered by nearly 900 distinct paintings of geometric shapes, people, and animals. In vivid shades of red, white, yellow, and black, their style resembles those of rock art found elsewhere in Patagonia, estimated to be a few thousand years old at most.
But to the trained eye of Guadalupe Romero Villanueva, an archaeologist at Argentina’s National Scientific and Technical Research Council (CONICET), some of the Huenul Cave paintings seemed older than the rest: A handful of badly weathered, comb-shap...

Coding changes that will impact radiology practices in 2024
Erin Stephens.The annual update to the Current Procedural Terminology1 (CPT) for 2024 has 230 new codes, 70 revised codes, and 49 deleted codes. In addition, there are 395 new diagnosis codes contained in the ICD-10-CM2 update, about one-third of them describing new ways to capture accidents and injuries. Although relatively few of these changes will impact radiology practices, it’s essential to know what they are and adjust your practice systems accordingly.
