IRB Information

NA-MIC data is overseen by both the Dartmouth CPHS and the NH State IRB. We have received approval from each entity to share deidentified data with NA-MIC researchers via the wiki. The link between shared data and private subject IDs is kept at Dartmouth in a locked cabinet, within a locked office, and outside researchers will not have access to this information. Data is not to be shared with researchers outside the NA-MIC consortium.

Data Access

A More detailed description of the data sets can be found here. Data includes:

• 6 Healthy Controls Data
  • SPGR
  • T2
  • fMRI (ER-RECOG task)
  • DTI
  • Hippocampus Traces – from Brains
  • Hippocampal ROIs – Binary ROIs
• MRI Data for 15 SZ
  • SPGR
  • Frontal Traces: 8 Structures (right and left) – from Brains

Collaborations

• Working with Steve Pieper and Gordon Kindlmann to correctly incorporate new 3T data into Slicer.
  • Have uploaded sample data to BIRN to address diffusion direction concern and eddy current correction testing. These action items were developed during May 19th, 2006 visit by Steve Pieper and Ron Kikinis to Dartmouth.
• Correspondence with Steve Pieper to help debug Slicer 2.6 for 64-bit Linux.
• Collaboration with Josh Snyder/David Tuch at Harvard on DTI Path of Interest Project.
• Correspondence with Josh Snyder/Xiaodong Tao to help create script to convert Dartmouth data to nrrd format.
• Collaboration with team at Harvard and Steve Pieper to help improve and get training on Slicer Editor, DTI-MRI module, and fMRI module.
• Collaboration with Shenton Lab to port Dartmouth fMRI tasks to Harvard site for local (Boston) data collection.
