Exploring the pros and cons of direct-to-patient drug programs
These programs may provide benefits in some cases. In others, however, there is a concern that they could actually lead to higher costs over time.
Augmented reality improves novice users' ultrasound skills
Using a virtual reality headset, the system, dubbed AR-VIU (augmented real-time volumetric imaging in ultrasound), creates a 3D rendering of anatomy based on 2D ultrasound images.
PAD patients minimize risk when they listen to their doctors
Patients who exercise and take all prescribed medications, for instance, experience better outcomes than those who do not.
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.

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.
