#### A.56.3.1 Enhanced PET Image IOD Content Constraints

Modality (0008,0060) shall have the value PT.

The General Image Module, Overlay Plane Module, VOI LUT Module, Supplemental Palette Color Lookup Table Module, and the Softcopy Presentation LUT Module shall not be used in a Standard Extended SOP Class of the Enhanced PET Image.

### Note

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

2. 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.

3. The Blending Softcopy Presentation State and Spatial Registration SOP Classes can be used to relate this SOP Instance to related image, registration, or fiducial SOP Instances.

4. If contrast was administered during a CT acquisition used for attenuation correction, this information can be obtained from the CT SOP Instances and is not encoded in the PET SOP Instances.
