Summary
The Vestibular-Schwannoma-MC-RC (VS-MC-RC) dataset contains longitudinal MRI scans of 160 patients with a single sporadic Vestibular Schwannoma (VS) from 10 medical sites in the United Kingdom. For all patients either a T1-weighted (T1w) or T2-weighted (T2w) scan, or both, are available. The dataset provides binary segmentations of the VS for all scan sessions. The dataset comprises up to three time points for each patient resulting in a total of 427 timepoints and 487 3D-images. These timepoints represent the first, central, and last MRI exams that the patients underwent. For 60 timepoints, both T1w and T2w are available, for 64 timepoints only T1w, and for 303 timepoints only T2w. Manual ground truth segmentations were obtained in an iterative process in which segmentations were: 1) produced or amended by a specialized company; and 2) reviewed by one of three trained radiologists; and 3) validated by an expert team. Using this dataset, researchers can develop and validate methods, for example, for automatic surveillance of Vestibular Schwannoma, which work robustly on images acquired at different hospitals.
Pre-processing
The MRI images are provided in DICOM format. All images were defaced using automatic affine registration or manual landmark registration with BRAINSFit and the template and face mask provided in pydeface. Segmentations are provided in NIfTI format
Comparison to VS-SEG dataset
Compared to the Vestibular-Schwannoma-SEG (VS-SEG) dataset which was acquired with a standardized protocol for radiation treatment planning on a single scanner at a single site, the VS-MC-RC dataset aims to capture the diversity of MRI scans encountered in a routine clinical setting; it contains a wide range of scan protocols and was acquired on multiple scanners by different manufacturers. In addition, the tumour manifestation in scans of this dataset is more diverse because it includes tumours at early stages and post-operative tumour residuals rather than only tumours specifically selected for radiation therapy.
Patient overlap with VS-SEG dataset
58 patients of the VS-MC-RC dataset were previously included in the VS-SEG dataset. These patients have a Patient ID that begins with “VS-SEG- “. Patient IDs of patients that are not part of the VS-SEG dataset begin with “VS-MC-RC-”. Please note that for most patients that are part of both datasets, the timepoints and MRI series included in one dataset are different from those included in the other dataset. However, 8 series are included in both datasets. These series are listed in the CSV file below. Please note that the VS-SEG dataset was not exported with the same software as the VS-MC-RC dataset. Therefore, the metadata of overlapping series might differ. Furthermore, different defacing algorithms were used so that pixel data of overlapping series are not the same in affected areas.
Embargoed data
This dataset is part of the challenge “Cross-Modality Domain Adaptation for Medical Image Segmentation” (crossMoDA). 126 timepoints that were included in the validation and test set of the challenge are currently under embargo and will be released in August 2024. Until then, 301 timepoints from 124 patients are available for download.
