Agenda for 9/21/05


Comparison of LSDIrecon and DTMRI scalar measures, also including Steve's "include zeros" functionality (details here)

  1. Differences in FA are always <0.25% (usually much smaller)
  2. Raul removed the Scale Factor, which seems to make Trace values very small compared to ADC
    • BUT DTMRI trace values are still consistent (in relative terms) with LSDIrecon ADC, i.e., always 250X smaller
  3. Including zeros (Steve's added button) did not make a difference. Does this mean 1) there is no difference, or 2) the "include zeros" button does not work?


Diffusion cases acquired Coronal AP (details here)

  • Fiber tracking seems to be fine on these cases


2 ROI method for DTI fiber tracking (details here)

  • I can't get it to work- please help!
  • "NOT" functionality: Raul is working on it


Higher resolution scans on 3T (details here)

  • Fibertracking was done after smoothing the tensor.


Fiber clustering (detailshere)

  • fiber backtracking/corpus labeling method?


DTI case for Lynn DeLisi (details from Sylvain to Raul here)

  • Marek, do we know what variables/examples she wants from us?



Other issues...

  • Stephan's LSDIrecon code (details here)
  • Background noise in DTMRI scalar measures (details here)
