[Insight-users] Re: CT or MR? How to know it from the DICOM header

[Ivan Macia]

Alam, Mathieu,

I checked the DICOM standard and seems like 0008 0060 "Modality" is an
attribute of type 1 this is, the element must appear and cannot have length
zero, correct me if im wrong. In any case, SOP Class Name should be also
valid.

Hope that helps

Ivan

Alam,

	I do not believe 'Modality' is a compulsary field. But you should
always be able to find the SOP Class Name from the DICOM Image:

http://imagerie.apteryx.fr/dicom/dicom_conformance.html

For instance you could find:

1.2.840.10008.5.1.4.1.1.2 which is CT Image Storage

or

1.2.840.10008.5.1.4.1.1.4 which is MR Image Storage
