Or it might be that the DICOM file is "compressed", a format that the
IDL
DICOM routines cannot read.
You might want to use one of the free DICOM viewers to extract and save
the
compressed JPEG image to a new file perhaps?
I hear that RSI is releasing a new medical product later this year which
will
handle compressed DICOM files, but you'll have to fork out $$$$ for
it...
It's all a bit of a pain - I'd llike to be able to read the latest scans
of
my very own Astrocytoma via IDL, but no, not with IDL.
