I saw a demo of this device at RSNA last year. It is quite small, which is their goal to make it as portable as it is. But, the opening where the body parts go is also small, and at this point too small I think to fit the whole body. It wou

This is really cool technology, as a neuroradiologist anything that helps decrease time/cost and increase availability of imaging is a big win. It should be clarified, though, that this machine uses a very weak magnetic field compared

MR is not always superior to x-ray for fracture detection, in fact, in the acute phase MR is often normal as marrow edema has not yet developed. Resolution is far worse than CT or plain film xray, making subtle non-displaced fractures impos

Interesting this should pop up, a few weekends ago I put together a simple quick search for ICD-10 codes (and Radlex, a radiology specific lexicon) at http://lex.orionmd.com . I'm sure there are other more powerful tools out
