By default itk::GDCMImageIO will properly detects valid DICOM file
(ref: PS 3.10-2008 from standard) even when no extension is specifiied
(.dcm is not required by the standard). So your file is not a valid
DICOM file, it is missing at least the magic number 'DICM' (at Offset
128) to properly be detected.
If this is correct, check with your vendor on how to obtain proper
(valid) DICOM files.
