If the scanner that the images were collected on was a model from before about 1993, then I'd guess that the files are in some form of the old ACR-NEMA format, possibly with Siemens' SPI extensions. I can't really help with format conversion here, unless you happen to be working on a very ancient Sun SPARC computer from about the same period. Perhaps some of the software from here could help:

I have a CD's of some images that were burned from our radiology department (Scanner manufacturer: Siemens). Our issue is related to file conversion.

SPM8 is unable to determine the file format and will not execute "DICOM import". "DICOM to ANALYZE" (a program we usually use to convert) will not make the conversion.

In addition, other programs (MRIcroN) also fail to recognize these images as DICOM.

We can VIEW the images in MRIcro, but it is unclear whether it recognizes them as DICOM or some other file format. Also if converting in MRIcro, the Analyze files are unreadable in spm8 and MRIcroN (just noise)

Has anyone else encountered a similar issue?

When DICOM images are packaged, are they modified in any way? Are these in fact DICOM images?

Thanks,
