### A.75.5 Parametric Map Functional Groups

Table A.75-2 specifies the use of the Functional Group Macros used in the Multi-frame Functional Groups Module for the Parametric Map IOD.

Table A.75-2. Parametric Map Functional Group Macros

Stored Value Color Range | C.7.6.16.2.26 | C - Required if Pixel Presentation (0008,9205) in the Parametric Map Image Module equals COLOR_RANGE.
Parametric Map Frame Type | C.8.32.3.1 | M
Unassigned Shared Converted Attributes | C.7.6.16.2.25.1 | U - May not be used as a Per-Frame Functional Group

#### A.75.5.1 Parametric Map Functional Groups Description

For the Derivation Image Functional Group Macro:

- For Purpose of Reference Sequence (0040,A170) BCID 7222 “Parametric Map Derivation Image Purpose of Reference” may be used.

- For Derivation Code Sequence (0008,9215) BCID 7203 “Image Derivation” may be used.

For the Real World Value Mapping Functional Group Macro, which defines the type of quantity, the method of generation and the units for the pixel values:

- For Concept Name Code Sequence (0040,A043) of Quantity Definition Sequence (0040,9220) BCID 9000 “Physical Quantity Descriptors” may be used.

- For Concept Code Sequence (0040,A168) for Concept Name of (246205007, SCT, "Quantity") of Quantity Definition Sequence (0040,9220) BCID 7180 “Abstract Multi-dimensional Image Model Component Semantics” may be used.

- For Measurement Units Code Sequence (0040,08EA) BCID 7181 “Abstract Multi-dimensional Image Model Component Units” may be used.

The Unassigned Shared and Per-Frame Converted Attributes Macros are included to allow acquisition-specific Attributes to be conveyed when they are relevant to the use-case. E.g., the echo time, flip angle or diffusion b-value might be useful to interpret a parametric map from an MR acquisition. Since some of these values may vary per-frame, it is appropriate to include them in the Functional Groups, rather than in the top level Data Set.
