I am sure that this experiment was initially conceived by grad students:
FKF Applied Research and the UCLA Ahmanson Lovelace Brain Mapping Center have released their Second Annual Ranking of the most effective Super Bowl ads using fMRI (functional Magnetic Resonance Imaging) brain imaging. Many of the Super Bowl ads stoked regions of the brain associated [...]

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 [...]

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 [...]

MRI, as an imaging modality, offers tremendous soft-tissue contrast without any use of contrast agents. Even beyond anatomic scans with T1, T2 or proton density weighting, other methods like arterial spin labeling or diffusion imaging exist which leverage both physics and physiology to tease out new information in a scan, making MRI the single most [...]

PROPELLER-EPI with parallel imaging using a circularly symmetric phased-array RF coil at 3.0 T: application to high-resolution diffusion tensor imaging
A technique integrating multishot periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) and parallel imaging is presented for diffusion echo-planar imaging (EPI) at high spatial resolution. The method combines the advantages of parallel imaging to [...]
