for those who aren't in the industry, DICOM files are a digital
imaging format typically used by the medical industry.  it contains an
embedded JPG and lots of patient/medical metadata, and also includes a
networking protocol for exchanging such data across processes:

a few questions to help us understand the problem better:

how are you opening the file?
how are you parsing the file, and what kind of data structure is
holding all the data?
where is this dictionary defined?

once we know this info, i'm sure we can help out more.

thanks,
