The following just came out over the SMRT mailing list:
Vendor issues new warning on Omniscan MR contrast for patients with kidney disease
GE Healthcare warned European providers Feb. 7 to discontinue the use of gadodiamide (Omniscan) for patients who may be at risk for a rare and life-threatening skin disease.

I missed “Just Science” week by a couple of weeks, so here is my post to try to make up for it:
I have recently been reading a book called “Junk Science” by Dan Agin, who describes himself as a neuroscientist and biophysicist. The book discusses the many ways that legitimate science is twisted/altered/slanted so [...]

In December, an MRI machine exploded due to a liquid nitrogen leak:
Two workers moving an MRI machine were injured Thursday after an explosion blew part of the machine into a wall. The workers were moving the machine at Atlanta Diagnostic Center in Kennesaw, said Firefighter Denell Boyd, a spokeswoman for the Cobb County Fire and [...]

via MedGadget,
Medtronic began the evaluation of its EnRhythm® MRI SureScan™ pacer, a technology designed for safe use in MRI machines, “under specified scanning conditions.” The company did not disclose what these specified scanning conditions are.
There’s a copy of the press release, too. I assume that certain kinds of scans are off-limits, like diffusion imaging. [...]

2007 may be a big year, at least according to industry spokespeople:
Low-cost MRI machines, super-fast Internet routers, and high-capacity power lines top the list of likely breakthroughs in the field of superconductivity in 2007, according to a ‘Top-10′ forecast list released today by Elie K. Track, Ph.D., senior partner, HYPRES Inc., a leading developer of [...]

Philip Gordon, M.D. is a neonatologist whose blog, Tales from the Womb, occasionally touches on MRI-related topics. He has a recent post about the trouble with MRI in neonatology that is well worth reading. He takes issue with the emerging practice of attempting to use MRI to predict neuro-developmental outcomes in preterm infants, pointing to [...]

Dixon imaging is a technique for separating out water and fat in an MR image that depends on the relative chemical shift between water and fat (as opposed to relying on the absolute resonance frequencies, as in saturation-based techniques). For someone just getting started in this area, or who is simply interested, here is [...]

RefScan is hardly the only MRI-geek website out there; another great one is Revise MRI, by Dave Higgins Ph.D. It’s primarily an educational resource, but there’s also a blog (Revising MRI) which has a broader scope. There’s even a discussion forum where people can ask MRI physics questions.
Some examples of cool posts on the [...]

That’s “not safe for work”, not “national science foundation” up there in the acronym. It was surely inevitable that this amazing, subtle and elegant technology would eventually be applied to more scatological pursuits. The following paper is a classic in this genre.
Magnetic resonance imaging of male and female genitals during coitus and female sexual [...]
