Dear AuntMinnie Member,
Can coronary artery calcium (CAC) scoring with CT predict the risk of coronary heart disease (CHD) in older patients? It can indeed, and it's an even more important factor than a patient's age, according to new research that analyzed pooled data from five large population-based studies.
A multi-institutional and multinational research group found that CAC scoring had a greater association with incident CHD than a patient's age in adults 60 and older.

Safety of CT, MRI contrast in neonates
Very little research has been performed on the use and safety of CT and MR contrast in neonates. Fortunately, a new study has concluded that the youngest of babies are not harmed by iodine-based CT contrast or gadolinium-based MRI contrast agents.
After a retrospective review involving a total of 280 neonates, researchers from the Children's Hospital of Philadelphia determined that neonates who received contrast agents didn't have a greater risk of renal toxicity than those who had noncontrast-enhanced studies. Importantly, they also didn't find any lingering ailments such as nephrogenic systemic fibrosis two years and four years later.

Minnies nominations
We're now accepting nominations for the Minnies -- AuntMinnie.com's annual event recognizing excellence in radiology.
Each year, the Minnies give radiology professionals the opportunity to acknowledge achievement in medical imaging. For the next several weeks, we'll be accepting nominations from our members for a variety of categories, ranging from Scientific Paper of the Year to Best New Radiology Software.
We'll assemble your nominations into a list of candidates that represent the cream of the crop in radiology. Then, our expert panel will select the winners through two rounds of voting, with trophies to be presented at RSNA 2017 in Chicago.
