A brief and hopefully final private equity in radiology post for now. I assure you no one starts a blog during their first year of medical school in 2009 and says, one day I hope to p**s on organized medicine and large corporations as a hobby forever. With that said… § The ACR runs a large and presumably quite profitable job forum. (I believe they outsource its management to a third-party company, but it’s on their website, and their branding is all over it.

Researchers have created a new brain imaging method that allows mild traumatic brain injuries (mTBIs) to be diagnosed, even when existing imaging techniques like magnetic resonance imaging (MRI) don't show any structural abnormalities. The technique involves loading gadolinium, a standard MRI contrast agent, into hydrogel-based micropatches that are attached to immune cells called macrophages.

Infants with enlarged perivascular spaces have a more than two-fold greater chance of developing autism compared with infants with normal perivascular spaces, according to researchers from the University of North Carolina in Chapel Hill. "These results suggest that perivascular spaces could serve as an early marker for autism," said study lead author Dea Garic, PhD, in a statement released January 2 by the university.

From “ How to Do Great Work ” by Paul Graham: Schools also give you a misleading impression of what work is like. In school they tell you what the problems are, and they’re almost always soluble using no more than you’ve been taught so far. In real life you have to figure out what the problems are, and you often don’t know if they’re soluble at all.

Entrants included a host of special methods that took advantage of human knowledge—knowledge of words, of phonemes, of the human vocal tract, etc. On the other side were newer methods that were more statistical in nature and did much more computation, based on hidden Markov models (HMMs).

We all know someone who's had a head injury that was 'only' a concussion, but even mild traumatic brain injuries can cause lasting damage, and the vast majority are never diagnosed. A team created a way to diagnose mild TBIs (mTBIs) even when MRI scans showed nothing, using the body's own immune cells called macrophages. They attached microparticle 'backpacks' containing a common MRI contrast agent to the cells, which migrated to the brain and allowed them to see evidence of inflammation in pigs
