A software issue could lead to the affected devices inadvertently moving, potentially making unintentional contact with patients or other equipment, according to the FDA.
Entire department of interventional radiologists resigns over failed negotiations
The negotiations pertain to disagreements on compensation and concerns over outdated equipment used during IR procedures.
AI turns low-quality MRI scans into helpful heart images
A team of biomedical engineers, radiologists and cardiologists has developed a new AI model capable of restoring low-quality cardiac MRI scans.
New AI-enabled, helium-free MRI system earns FDA clearance
The scanner requires just 0.7 liters of liquid helium for cooling—a fraction of the more than 1,500 liters standard systems need to operate safely.
How the shape, size and location of calcified carotid plaques affect stroke risk
A new analysis provides further insight into factors affecting plaque stability and subsequent ischemic events

Despite higher Alzheimer’s risk, patients can handle amyloid PET exam results

Those who learned they had elevated amyloid levels did not suffer from more short-term anxiety, depression or suicical thoughts, experts reported in JAMA Neurology.

New radiation-dose estimation process moves nuclear medicine closer to customized cancer therapy

Researchers used a single SPECT/CT scan performed post-therapy to estimate how much radiation a patient’s tumor and at-risk organs will absorb.

Ultrasound, 3D printing combine to help blind parents feel their babies' faces

The idea came about after a sonographer at Johns Hopkins wondered if the technology could be used to create a model for a blind mother.

How one mobile mammography program took on breast cancer in underserved women

Authors of the five-year Project Valuable Area Life-Saving Exams in Town program say their results should prompt the creation of similar strategies across the U.S.

MIT’s AI system diagnoses chest conditions on x-rays, but knows when a radiologist could do better

The hybrid platform proved more accurate at detecting enlarged heart cases than machine learning or a human reader working independently.

‘Pink card’ program brings walk-in screening mammograms to vulnerable patients

Massachusetts General Hospital’s academic breast imaging division launched its pilot in November 2016, sharing their results recently in JACR.
