Trouble with opening a DICOM file from Siemens Vida


I have trouble working with images from Siemens Vida. I heard that there is some special new format in use, as I looked at the file it also contains some xml (although it is a DICOM file). Does anyone have experience with this?

mrinfo file gives me

mrinfo: [ERROR] unknown format for image file
mrinfo: [ERROR] error opening image

I can share the file per E-mail.



Hi @amirzolal,

Happy to take a look, feel free to send me the file directly (

Sent per E-mail. Thanks alot!

OK, I’ve had a look at the file, and it opens up straight away in mrinfo or mrview:

$ mrinfo  10000539/

What was the problem exactly? Maybe you’re running very old version? What does mrinfo -version report?

Oh … not that old at all … i ran mrinfo on the first file in the directory thinking it would read the whole series. When I run it on the directory everything is ok.

Sorry. Me stupid.
