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 information 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”.
