Hi!
I get the following error when trying to load DICOMs from SPECT and from CT: “3d slicer could not load as a scalar volume”.
I have checked the DICOM tag, but can not see that anything is missing. The tag is copied below. Any ideas about what could be wrong?

Hi,
I am not able to load DICOM files from SPECT or CT. They seem to be imported fine, but when I try to load them to Slicer I get the follwing error message: “3d slicer could not load as a scalar volume”. I can not see anything missing in the DICOM tag (copied below). Any ideas about what the problem may be?

Dear Andras Lasso,
Thank you very much for your response. After sending the request I have resolved the issue myself. The trouble was that
the files did not have an entry in the Accession Number tag.
Best regards,
