[BIC-announce] MGH Talk Tomorrow

[Rick Hoge]

Please see below - 

Dr. Andre van der Kouwe, from Harvard Medical School and Massachusetts General Hospital in Boston, is giving a talk tomorrow (Thursday Dec. 1st) at 12:00-1:00 pm in Room L7-140 of the Montreal General Hospital. 
I think it will be of broad interest to the neuroimaging groups, and I would appreciate if you could disseminate it to your list. 
 
Title: Motion Correction and Parameter Mapping in Brain Morphometry Studies. 
By: Andre van der Kouwe, Assistant Professor in Radiology at Harvard Medical School, Assistant in Physics at Massachusetts General Hospital
 
In the last few years it has become evident that motion during MRI acquisitions can bias the results of research studies. In brain morphometry studies, structural changes such as cortical thinning can be explained by disease or by relatively increased motion during the acquisition of brain scans in the diseased population. Similarly, long range connectivity in functional and diffusion studies decreases if there is motion during the acquisition, possibly masquerading as a disease-related brain change. In this talk, navigator-based methods for real-time correction of head movement during structural scans will be presented. An efficient method for collecting parameter maps (spin density, T1 and T2) with a ten-minute protocol will also be presented. The protocol consists of a multi-echo multi-inversion time MPRAGE and a two flip angle FISP scan. Apart from the parameter maps, the protocol also yields the B0 field map, separate water and fat images, and rudimentary resting state functional data.
 
Thanks,
