  • Slide 1
  • National Alliance for Medical Image Computing http://na-mic.org Core 3-1 Schizophrenia NA-MIC National Alliance for Medical Image Computing http://na-mic.org Clinical Neuroscience Division, Laboratory of Neuroscience, Department of Psychiatry, Harvard Medical School Surgical Planning Laboratory, MRI Division, Department of Radiology Brigham & Womens Hospital, Harvard Medical School

  • National Alliance for Medical Image Computing http://na-mic.org Data All the legacy data has been converted to one single file format, nrrd. Total of 188 morphological cases and 80 diffusion cases have been uploaded. Each case has a unique BIRN identifier. Information about diagnosis, data parameters and labels associated with Region of Interests (ROI) are on the BIRN site in the following Excel files: - morph-NAMIC.xls : Gives diagnosis, age, gender as well as the ROIs drawn for each morphological case. - morph-ROI-description.xls: Gives for each ROI set, the label corresponding to specific structures. - diffusion-NAMIC.xls: Gives diagnosis, age, gender, ROIs drawn and when existing, the corresponding morphological data ID number. - diffusion-ROI-description.xls: Gives or each ROI set, the label corresponding to specific structures.
