IWOAI 2019 Knee MRI Segmentation Challenge

Name: IWOAI 2019 Knee MRI Segmentation Challenge
License: The challenge data was derived from the Osteoarthritis Initiative. Independent redistribution was not verified, so access and reuse should be interpreted through the upstream OAI/NDA conditions.

The IWOAI 2019 challenge evaluated knee MRI segmentation methods on 3D DESS images from an OAI-derived subset, including femoral, tibial and patellar cartilage plus meniscus labels.

Notes

The paper describes 88 subjects with two time points each, for 176 MRI volumes. Because the data is OAI-derived, this record is tracked as an application/access-limited derived challenge rather than an independently downloadable dataset.

This record is a pointer. Licence and access terms are recorded as they stood on the verification date above; what binds you is the dataset's own licence text. Confirm at the source before use.
