It's only the second day of the six-day holiday season behemoth known as RSNA, and already we've picked up on a few trends. Radiology cloud computing (think of it as Google Docs for imagers) is a hot topic, with several vendors showcasing new solutions. There's a chill in the air, and also riding the breeze is word of new elastography applications for both MR and ultrasound. We introduced you to the concept of iterative reconstruction back in May at MDCT (our inaugural blogging run -- how distant those days seem now!), so it's no surprise that it's all the buzz at the culminating conference of the radiologist's year. What else is happening? Anything caught your eye that you'd like your faithful StatRead correspondent to investigate further?
