EPISURG is a clinical dataset of T1-weighted magnetic resonance images (MRI) from 430 epileptic patients who underwent resective brain surgery at the National Hospital of Neurology and Neurosurgery (Queen Square, London, United Kingdom) between 1990 and 2018.
The NIfTI files are anonymised and the images have been defaced to further protect the patients' identity.
The dataset comprises 430 postoperative MRI. The corresponding preoperative MRI is present for 269 subjects.
Three human raters segmented the resection cavity on partially overlapping subsets of EPISURG:
- Rater 1: 133 subjects (researcher in neuroimaging)
- Rater 2: 34 subjects (clinical scientist)
- Rater 3: 33 subjects (neurologist)
