 In May 2013, Hans Johnson created the repository `Slicer/itkMGHImageIO` enabling ITK
-based programs to support reading and writing MGH files. See [Slicer/itkMGHImageIO@4fa1fd815](https://github.com/InsightSoftwareConsortium/itkMGHImageIO/commit/4fa1fd8155a697bdd1a2c73f475178220d9fb09f). Between 2013 and 2021, this

 more general implementation has been developed with contributions from Hans Johnson, Mathew Seng, Xiaoxiao Liu, Matt McCormick, Jon Haitz Legarreta, François Budin, Zach Williamson and Jean-Christophe Fillion-Robin.
 
 In September 2015, starting with Slicer commit [Slicer/Slicer@184e907df](https://github.com/Slicer/Slicer/commit/184e907df), Slicer was updated to use the IO provided by `Slicer/itkMGHImageIO` through the ITK remote module mechanism.
