Daniel,

I'm sorry I missed your message. I thought I was subscribed to receive an email for posts in this forum, but apparently I was only subscribed to "general-discussion" but not "help". 

I haven't seen what you describe before. It sounds to me like you have a mismatch across multiple volumes that are getting jumbled back together. 

DICOM always finds new ways to be unusual, even when we think we've seen everything (which includes some really large and varied studies like ADNI and SCAN). Is there any way you can de-identify your DICOM sufficiently that you can email it to me, and I can take a look?
