Seven-second X-ray assesses severity of regurgitation congenital heart defect patients
Moving X-ray images can help evaluate pulmonary regurgitation in Tetralogy of Fallot patients.
Researcher undergoes over 100 MRI scans to understand how sleep affects the brain
Armed with an advanced 7T MRI and one very committed graduate student, researchers are gaining new insight into how sleep patterns affect brain health.
CT-FFR standardized in new SCCT-SCAI consensus statement
FFR-CT literature has reached a state of maturity where experts can comfortably start to provide guidelines to the wider community.
Women on GLP-1 medications may be less likely to develop breast cancer
The study, which was managed by the American College of Radiology, is raising important questions related to the benefits of GLP-1 use.
SPECT agent could help guide lung disease treatments, new data suggest
In February, the imaging agent made its way onto the U.S. Food and Drug Administration’s Fast Track to clearance.

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.

Anticoagulants after TAVR: 5-year survival data favor DOACs over VKAs

However, that one finding does not tell the whole story. Researchers also found that DOACs may increase a TAVR patient's risk of a disabling stroke.

Michael Garshick, MD, director of the cardio-rheumatology program, cardiologist and assistant professor, Ronald O. Perelman Department of Dermatology, NYU Grossman School of Medicine, explains the role of inflammation in coronary disease development and how this risk factor can be detected and treated.

Targeting coronary inflammation helps cardiologists provide better care

Michael Garshick, MD, examines the role of inflammation in coronary disease development, detailing how this risk factor can be detected and treated.

Low field 0.55T MRI images as diagnostically useful as 1.5T for abdominal scans

Researchers from the University of Michigan scanned 52 patients at multiple field strengths to make the comparison.
