Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

FDA issues recall on Philips spectral CT systems
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The negotiations pertain to disagreements on compensation and concerns over outdated equipment used during IR procedures.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

Dynamic contrast-enhanced MRI helps clinicians diagnose Bell’s palsy

The approach accurately detected facial muscle abnormalities associated with the condition, according to research published in Clinical Radiology.

Acoustic noise reduction in MRI significantly reduces patient discomfort without hurting image quality

Loud sounds emitting from magnetic resonance machines can erode the patient experience, but Swiss experts may have found the fix.

Follow-up ultrasound ovarian imaging offers little benefit to patients, experts advise

The incidental spotting of these “simple cysts” has increased in recent years, leading to unnecessary surveillance, Mass General researchers noted.

Teleradiologists’ accuracy diagnosing COVID-19 underscores remote reading’s importance during emergencies

Senior radiologists agreed with their remote peers' interpretations in most instances, according to a new multi-center study published in European Radiology.

Man died after receiving ‘unnecessary’ contrast scan, despite kidney issues

Radiologists signed off on the exam, but never took the proper steps to determine the 91-year-old's contrast risks.

Scientists look to functional MR brain imaging to understand America’s political divide

Experts from three prominent institutions hope their neuroimaging work will inform new interventions to address partisan discord.

CTA scans for stroke double as quick, cost-effective tool for diagnosing COVID-19

Pairing imaging results with self-reported symptoms proved 83% accurate at spotting patients with the virus, Albert Einstein College of Medicine neurologists found.

Cardiac MRI contrast agents are low-risk and safe for ‘overwhelming’ majority of patients

German researchers reported acute adverse effects in only 0.38% of contrast-enhanced exams, with few severe reactions.
