Dear MIDI-B participants and interested parties: Earlier this week we were notified by the MICCAI 2024 Challenge Chairs that due to a planning error, related to the planning of virtual events at MICCAI central, all virtual events are to be held outside of the MICCAI conference dates (Oct 6-10). However, there?s a possibility that the events may be advertised through the MICCAI website. Therefore, the MIDI-B session WILL NOT take place on Oct. 10, 2024. As such, we have decided to hold the MIDI-B session (now referred to as the MIDI-B Challenge Workshop, 2 weeks later, on **Thursday, Oct 24, 10 am- to 2 pm EST**. The link for the virtual workshop on WebEx: [MIDI-B Challenge Workshop](https://cbiit.webex.com/cbiit/j.php?MTID=m33e2783bc9a2256fd136cec55a5ba751). Registration will not be required, and the meeting will be open to the public. If you registered to attend the Satellite Events on Oct 10, you may only do so in person. Otherwise, it may be possible to request a refund. At this point, a refund is not guaranteed but MICCAI is trying to deal with this crisis. We will pass on more information about refunds as we hear from the MICCAI Challenge Chairs. We apologize for the inconvenience and look forward to your participation in the workshop. Please let us know if you have any questions The MIDI-B Organizing Committee
