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.
-
For Measurement Units Code Sequence (0040,08EA) in the Real World Value Mapping Sequence (0040,9096) DCID 301 “Multi-energy Material Unit” shall be used.
