These MRIs are pre-operative examinations performed in 159 subjects with Low Grade Gliomas (WHO grade II & III). Segmentation of tumors in three axial slices that include the one with the largest tumor diameter and ones below and above are provided in NiFTI format.  Tumor grade and histologic type are also available.  All of these subjects have biopsy proven 1p/19q results, performed using FISH.  For the 1p/19q status "n/n" means neither 1p nor 19q were deleted. "d/d" means 1p and 19q are co-deleted.

1p19q Status and Histologic Type

Previously the segmentations of the tumors were provided in NIfTI format and only included three axial slices (the one with the largest tumor diameter and ones below and above).   In version 2 segmentations of the entire T2 signal abnormality are provided in DICOM-SEG format.
