Hi Manuel,

   I have added a warning section of the documentation of this class. In 
summary, vtkDICOMImageReader does not handle all kind of DICOM files 
defined in the standard.

Warning:
     This reader might eventually handle ACR-NEMA file (predecessor of 
the DICOM format for medical images). This reader does not handle 
encapsulated format, only plain raw file are handled. This reader also 
does not handle multi-frames DICOM datasets.
...

This is just a guess. If you are sure this is a plain raw DICOM file, 
send me the file, so I can have a look at it.
