Data set of brain MRI from stroke patients released to public

Researchers from the University of Southern California (USC) have archived and shared an open-source data set of brain MRI from stroke patients known as the Anatomical Tracings of Lesion After Stroke (ATLAS).

FDA paves way for domestic creation of No. 1 imaging radioisotope

The U.S. Food and Drug Administration (FDA) and the Nuclear Regulatory Commission (NRC) on Feb. 8 announced the approval of the RadioGenix System, which may help stabilize the United States’ supply of a radioisotope crucial for medical imaging.

Maryland nonprofit to test handheld cardiac ultrasound device

The democratizing power of technology is undeniable—as it has put a world of information into a person’s pocket or purse. Cardiac ultrasound, however, isn’t exactly top of mind for technologies that will be the next DIY sensation. But one nonprofit plans to introduce a handheld imaging device to increase availability of ultrasound while reducing costs.

MRI shows crash diets temporarily hamper heart function

Low-calorie “crash” diets actually cause a heart to become fatter in the short term, impairing its function, researchers reported at CMR 2018.

7 more payers to cover noninvasive test for coronary artery disease

Seven new commercial payers are covering the use of the HeartFlow FFRct Analysis, a noninvasive technology that allows clinicians to view a simulated, three-dimensional model of a patient’s coronary blood flow. More than 185 million patients will now have access to HeartFlow, the company announced Feb. 1.

Researchers propose new method for predicting AAA growth, rupture

Using multimodality imaging to assess Fluorine-18-sodium fluoride (18F-NaF) activity could help clinicians better predict whether abdominal aortic aneurysms (AAAs) are likely to grow more rapidly and eventually rupture, researchers reported in the Journal of the American College of Cardiology.

New registry aims to improve quality of cardiovascular imaging

The American Society of Echocardiography (ASE) announced Jan. 29 its ImageGuideEcho registry is open to U.S. physicians. ImageGuideEcho is the first registry exclusively devoted to measuring quality in cardiovascular ultrasounds.

Whole-body imaging links heart, brain inflammation after MI

A new study using whole-body molecular imaging identified a shared inflammatory response between the cardiovascular and central nervous systems following myocardial infarction (MI), possibly adding insight to the reported connection between cardiac injury and cognitive decline.

Seeing the Big Picture: Training Today’s Imagers to ‘Think Multimodality’

Cardiologists are receiving more exposure to different imaging modalities during their fellowships, but their job prospects and training vary widely. A more comprehensive and multimodality training approach could lead to better results.  

Unreliable supply of nuclear imaging isotope spurs plans of US production

American patients consume nearly half of the world’s supply of Molybdenum-99 (moly-99), a radioisotope that is crucial to most nuclear medicine imaging procedures. Yet there are only six government-owned nuclear research reactors that produce moly-99 and none in North America, prompting concerns about the supply chain of a product that has a shelf life of only a few days due to rapid decay.
