#### A.32.5.3 Video Endoscopic Image IOD Content Constraints

##### A.32.5.3.1 Modality

The value of Modality (0008,0060) shall be ES.

### Note

The use of a single value for Modality recognizes the fact that the same acquisition equipment is often used for different purposes (e.g., laparoscopy and colonoscopy). This means that Modality is not useful to distinguish one type of endoscopy from another when browsing a collection of studies. Therefore, the use of Procedure Code Sequence (0008,1032) and Anatomic Region Sequence (0008,2218) in the image instances and in the query response is recommended, though gathering sufficient information to populate these attributes in an unscheduled workflow environment (i.e., in the absence of Modality Worklist) may require operator intervention.
