Having spent over a decade developing MR hardware, the Zaitsev group in Freiburg has tried their hand at “basically everything but the magnet itself.” Lacking the Big Budget of industry, they favor a different approach to innovation: creating “strange things” with the “means at hand.” Sebastian and Maxim here discuss one of the fruits of this design philosophy: their 84-channel gradient system.

Kawin Setsompop and Larry Wald are old friends of MRM Highlights, and their work has been prominently featured in our magazines (here, here and here). In their most recent MRM paper, they complement their simultaneous multi-slice (SMS) acquisition with an additional 3D RF-encoding for each 3mm slice (or thin slab), in order to push the resolution of diffusion imaging to 600 µm isotropic in the brain. This technique nicely solves the issue of phase corruption in multi-shot MRI acquisition.
In their paper entitled “Multishot echo-planar MREIT for fast imaging of conductivity, current density, and electric field distributions”, Drs. Munish Chauhan and Rosalind Sadleir propose an accelerated technique to image electrical conductivity based on MRI. Their goal is not only to image conductivity of biological tissues, but more ambitiously to map neural activity using this fast technique. Let’s hear their story behind the paper.
