Hantavirus on imaging: What radiologists need to know
Two months after a cluster of cases occurred on a cruise ship, experts are offering insight into how radiologists can help spot the "silent" signs of the deadly virus on imaging.
Imaging offers new insight into how GLP-1 medications trigger weight loss
The slimming effect of medications such as Zepbound expands beyond appetite suppression alone, new imaging insights reveal.
First US patient enrolled in device study to reduce coronary microvascular dysfunction
The self-expanding A-Flux device is implanted in the coronary sinus to increase pressure on the venous side of the heart and improve perfusion in smaller vessels.
Advances in leadless conduction and Bachmann’s bundle pacing next frontier in physiologic pacing
Leadless pacing in the Bachmann's bundle may be the next phase in the evolution of cardiac pacing technology.
Vibrations used to extract EP leads in first-in-human study
A novel vibration-based extraction technique appears to offer safety, efficiency and a simple, rapid, alternative to conventional lead removal.

Light-powered 3D imaging system guides vascular surgeries without X-ray

The Philips LumiGuide utilizes a fiber optic guidewire with AI-assisted recognition to map the body arteries with light.

Saarland University adopting Sectra Education Portal to enhance medical learning

The German institution will have access to the portal for training radiology techs in a patient care setting.

Aycan and Enspectra partner for clinical trials on cellular imaging system

The VIO system visualizes and captures images at the cellular level for improved diagnostics.

Multiple factors can interfere with pulse oximetry accuracy including skin pigmentation. Multiple studies have shown the inaccuracy of current pulse oximeters in patients with darker skin tones than whites, often over estimating their oxygenation when in fact they are hypoxic.

Inaccurate pulse oximeter readings impact Black heart failure patients and FDA plans to address this

Black patients are already less likely to receive LVADs or transplants compared to whites, and these inaccurate readings can further widen the disparities.

Examples of photon-counting coronary angiography showing how clarity improves as the thickness of the image is reduced. Top: 60-year-old female, with noncalcified plaque (arrowheads) and coronary stenosis (inset images). The reduced section thickness did not affect assessment in this patient. Bottom: 56-year-old female with calcified plaque (arrowheads) and coronary stenosis. The reduced section thickness leads to less calcium blooming and therefore a less severe percentage of stenosis.

Coronary artery disease classification improved with photon-counting CT

After a photon-counting CT, 54% of patients had their coronary artery disease classification downgraded.

Focused ultrasound may alleviate pain without drugs, study finds

Researchers from Virginia Tech uncovered physiological changes from altering the way the brain perceives pain.

Artifacts from hair on X-rays shed light on health equity gap

Do radiologists see how the hair styles of Black and brown people impact imaging exams?

Microrobots guided by an MRI eradicate liver cancer

The technique was successful in a proof-of-concept animal study, but human trials are a long way off.
