About NeuRoi

NeuRoi is a locally developed software for processing MRI images. It will work with Analyze and some Nifti images.

NeuRoi is free software, and you are welcome to redistribute it under certain conditions.

Please note:

  1. NeuRoi works on Windows; it has been tested on XP and Vista.
  2. It also seems to work in Linux using WINE.
  3. NeuRoi comes with ABSOLUTELY NO WARRANTY.

Coordinate based Meta-Analysis

CBMA

NeuRoi can be used to perform coordinate based meta-analysis.

Region of interest analysis

Neuroi1

NeuRoi can be used to perform region of interest (ROI) analysis.

  • Semi automated ROIs
  • Manually defined ROIs
  • Statistics/histograms for ROIs

Measuring cervical spinal cord atrophy

NeuRoi spinal cord

NeuRoi can be used to measure upper cervical cord atrophy with a correction for partial volume. The function incorporated is detailed in:

  • Tench, CR, Morgan, PS and Constantinescu, CS (2005). "Measurement of cervical spinal cord cross-sectional area by MRI using edge detection and partial volume correction." J Magn Reson Imaging 21 (3): 197-203.

Diffusion tensor functions

 tractography

NeuRoi can perform several DTI functions:

  • Convert diffusion weighted MRI to DTI
  • Convert DTI to scalars: FA, RA, TRACE, eigenvalues
  • Use tractography to extract specific fibre tracts, as detailed in Tench, CR, Morgan, PS, Wilson, M, et al. (2002). "White matter mapping using diffusion tensor MRI." Magn ResonMed 47 (5): 967-72.  
 

Other functions

NeuRoi has several other functions to help analyse MRI images:

  • Image coregistration (6 parameter or include scale and shear parameters)
  • Image coregistration (6 parameter or include scale and shear parameters)
  • Reformat images (change voxel sizes etc.)
  • Image smoothing
  • Inhomogeneity reduction
  • Remove noisy background
  • Extracting the brain using a template
  • Fit T1 relaxation times to inversion recovery images
  • Compute MTR images
  • Histogram Equalisation
  • Phase unwrapping
