A.3.3.1 CT Image IOD Content Constraints
If Multi-energy CT Acquisition (0018,9361) is YES the following constraints will apply:
•The Contrast/Bolus Module shall be present if contrast was administered even if images are processed to remove contrast inform- ation from the pixels, e.g. Virtual Non-Contrast images.
•The Real World Value Mapping Sequence (0040,9096) shall be present in the General Image Module.
•The Defined CID for Measurement Units Code Sequence (0040,08EA) in the Real World Value Mapping Sequence (0040,9096) is CID 301 “Multi-energy Material Units”.
