A. Enhanced MR Color Image IOD Content Constraints

The General Image Module, Overlay Plane Module and VOI LUT Module shall not be used in a Standard Extended SOP Class of the Enhanced MR Color Image.

Note: In order to annotate images, whether during acquisition or subsequently, SOP Instances of the Color Softcopy Presentation State Storage or the Structured Report Storage SOP Classes that reference the image SOP Instance, may be used.

No standard mechanism is provided for inclusion of annotations within the image SOP Instance itself, and implementers are discouraged from using private extensions to circumvent this restriction.

Color Softcopy Presentation State Storage Instances that are generated during acquisition may be referenced from the Image SOP Instance by using the Referenced Presentation State Sequence in the MR Image and Spectroscopy Instance Macro invoked from the Enhanced MR Image Module. See C.8.13.2.

The Photometric Interpretation (0028,0004) shall be RGB for uncompressed or lossless compressed transfer syntaxes that do not involve color space transformations, YBR_ICT for irreversible JPEG2000 transfer syntaxes, YBR_RCT for reversible JPEG2000 transfer syntaxes, YBR_PARTIAL_420 for MPEG2 transfer syntaxes and YBR_FULL_422 for other lossy compressed transfer syntaxes.

The Pixel Presentation (0008,9205) shall be TRUE_COLOR.
