MRI of neonates

February 12, 2007

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 [...]

A Primer on Dixon Imaging

February 11, 2007

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 [...]

Revising MRI

February 11, 2007

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 [...]

NSFW MRI: Sex at 1.5T

February 10, 2007

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 [...]

Diffusion Tensor Imaging feed

February 8, 2007

I’m adding the DTI feed to the right sidebar now instead of its own page. I still would like to solicit suggestions for other real-time feeds off of PubMed, so leave a comment with your favorite queries.

brain scans and superbowl ads

February 6, 2007

One of the more interesting abstracts from last year’s ISMRM in Seattle has now been published as a full manuscript:
Propeller EPI in the other direction
A new propeller EPI pulse sequence with reduced sensitivity to field inhomogeneities is proposed. Image artifacts such as blurring due to Nyquist ghosting and susceptibility gradients are investigated and compared with [...]

150 years of intellectual writing

February 6, 2007

The Atlantic Monthly has opened its extensive archives in honor of its 150th birthday. The collection is organized into broad categories, including traditional ones like religion, politics, and women’s rights; there are also more intellectual ruminations like idealism and practicality and markets and morals. Naturally there are technology and science categories as well, and the [...]

Open Peer Review and MRI

February 5, 2007

I have decided that my inaugural post on this respectable, scientific blog should, of course, be filled with rampant speculation and ungrounded commentary. Sadly, Aziz does not have that “Organizing the Secret (Yet Open-Source) Cabal that Shall Rule ISMRM” tag for this blog…Respectable commentary on image reconstruction coming later in the week.
One thing that [...]
