Image Format

Images are presented in the nii format. Each image can be loaded by any program that supports nii format, including most ITK and VTK-based applications (e.g., Slicer).

There are two patient data sets. For each of them, there are datasets for 4 different modalities for both Acute and Chronic Stage. These modalities are:

  1. Fluid-attenuated inversion recovery (FLAIR) data set: Fluid-attenuated inversion recovery (FLAIR) is an advanced magnetic resonance imaging sequence that reveals tissue T2 prolongation with cerebrospinal fluid suppression, allowing detection of superficial brain lesions [1].
  1. Gradient Recalled Echo (GRE) data set:
  1. T1
  1. T2

Susceptibility-weighted imaging (SWI) and DTI data sets are not available at the moment.

Detailed information about each data sets are provided in the table belows:
