news flash: emotions sometime trump rational thought! Shocking, I know. Though I was intrigued at how the fMRI paradigm in this case provides a neat empirical example for why prisoner’s dilemma models don’t translate well into real-world practice:
A classic economic example is the “ultimatum game,” in which one participant gets 10 $1 bills (or loonies, [...]

An editorial in the Journal of Nuclear Medicine (J Nucl Med. 2007 Mar;48(3):331. PMID: 17332606) argues that combination PET/MRI systems are the future and will supplant PET/CT:
In a number of ways, the path to PET/MRI has been reverse of that to PET/CT. The first PET/CT design emerged from industry–academia collaboration and was a prototype for [...]

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. [...]

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 [...]

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 [...]
