I. Major Decision Points

II.Critical Path Sequence-MTC

  • A. Select patient(s)
  • B. Select area(s) of brain/body to scan with appropriate coverage
  • C. Select fMRI protocol parameters (BOLD, epoch length)
  • 1. Research Agreement with MRI Company (GE)
  • 2. Install to enable Research Mode for MRI protocol hard key (chips)
  • D. Train MRI Research Tech (specific pulse sequence parameters)
  • E. Train patient (neurocognitive tasks, timing)
  • 1. Task depends on brain location/functional relation
  • 2. Kind and Quantity control to eliminate head movement
  • F. Immobilize patient's head (flow, foam, tape)
  • G. Run scan series (T1 Sag, Ax, loc; EPI BOLD) collect 128 - 1,700 images
  • H. Extract images from MRI storage-reconstruct and decompress (E & D tools)
  • I. Move images to workstation (FTP protocol, Binary Type)
  • J. Delete temporary image files from MRI hard disk
  • K. Sort images into epochs
  • L. Sift images (using middle six of ten in epoch)
  • M. Compute mean densities for
  • 1. Regions of interest (ROI's),
  • 2. control areas
  • N. Analyze mean densities of ROI's statistically (NIH-Image, Osiris)
  • 1. SYSTAT: ANOVA, representative t-tests
  • 2. CLUSTERING Algorithms
  • 3. Friston's paradigms
  • 4. Quality assessments for reliability
  • O. Construct composite image with statistical densities
  • 1. assign color schemes (RGB, CYMK, etc)
  • 2. represent density by color look up tables (CLUT's)
  • P. Co-reference anatomical and functional images for fMRI localization (NIH-Image; Photoshop)
  • Q. Compare results to Brain Image Repository, UTSAMC
