About this dataset

Vestibular-Schwannoma-MC-RC is a multi-center routine clinical MRI dataset for unilateral sporadic vestibular schwannoma. It contains longitudinal scans from 160 patients across 10 UK medical sites, with up to three selected timepoints per patient. Images are provided as defaced MR DICOM and retain heterogeneous clinical acquisition protocols across Siemens, Philips, GE, and Hitachi scanners. The source paper reports screened imaging dates from February 2006 to September 2019; TCIA study dates are shifted for privacy.

MedSeg imports all public MR image series. Reference masks are attached where the public 2023 NIfTI segmentation ZIP provides a matching mask; newer v2 image-only series remain available without labels.

What you can do with it in MedSeg

Copied cases behave like normal project series - the public image bytes are linked, not duplicated, so copies are instant and take no extra storage.

Copy cases into a project.
Filter, multi-select, copy - reference masks come along if you want them.
Run AI segmentation.
TotalSegmentator, MRSegmentator, nnInteractive 3D clicks/scribbles, or text-prompted VoxTell.
Edit and measure.
Brush, lasso, fill, oblique planes, volumes in ml - in the browser.
Train your own nnU-Net.
Correct masks on a handful of cases and train a custom model on hosted GPUs.
