Full disclosure: I am the CEO of Innolitics, a development firm that specializes in medical imaging applications.

The most authoritative source on DICOM is the free standard:

https://www.dicomstandard.org/current/

It is not particularly easy to read and thus not a great starting place.

The DICOM forum is a good place to ask questions:

https://groups.google.com/forum/#!forum/comp.protocols.dicom

David Clunie, a very nice guy and the editor of the DICOM standard, is active on this forum. He also has is own website that has many other links:

If you are interested in parsing or generating DICOM files, our DICOM standard browser is a great resource:

I also wrote a very brief article about DICOM, which was meant to be the first in a series of articles, but alas I have been to busy to continue them:

Oh, and here is a pretty good blog about DICOM:

Checkout his "DICOM Tutorial" in the sidebar.

If you have any particular questions about DICOM, message me and I would be happy to try and answer them.
