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.

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
FDA approves expanded use of PET imaging agent
The product's updated indications include quantification and long-term monitoring of amyloid plaques on imaging.
Low dose GBCA effective, safe for pediatric imaging
Although gadopiclenol is approved for adults and children ages 2 and older, there is limited data on its use in the pediatric population.

Simple ECG score helps estimate MI infarct size

A simple ECG score could help physicians estimate infarct size in patients with prior MI, according to work published Jan. 24 in the Journal of the American Heart Association.

Automated analysis tool assesses thyroid nodules as well as radiologists

Researchers have developed a new quantitative framework that evaluates thyroid nodules at a level comparable to two expert radiologists.

PET/MRI spots breast cancer biomarkers for risk-based screening methods

Imaging markers such as breast parenchymal uptake varied greatly between women with benign and malignant lesions, according to a study published in the Journal of Nuclear Medicine.

How AI reduces radiation dose, but not quality, of key imaging findings

Deep learning-based reconstruction (DLR) can reduce the radiation dose associated with low-dose chest and abdominal CT scans without sacrificing image quality, according to a new study published in the American Journal of Roentgenology.

ACR: Risk of administering CT contrast in patients with kidney disease ‘has been overstated’

The National Kidney Foundation joined the college in releasing a new consensus document that answers key questions and offers recommendations for using IV contrast in patients with impaired kidney function.

Medical imaging, radiation therapy professionals urged to embrace AI

The American Society of Radiologic Technologists (ASRT) has published a new white paper on AI and its potential impact on the work of medical imaging and radiation therapy professionals.

AI boosts quality of brain MRI images

AI algorithms can improve the quality of brain MRI images, according to new findings published in Neurocomputing.

Cardiac MR comparable to FFR for evaluating nonculprit lesions after STEMI

A study published in the latest edition of JACC: Cardiovascular Imaging suggests cardiac magnetic resonance imaging can be as effective as measurements of fractional flow reserve in evaluating nonculprit lesions after STEMI.
