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”.​
