# QQQ Parametric Maps (Informative)

## QQQ.1

This Annex contains examples of the use of the Parametric Map IOD.

### QQQ.1.1

This Section contains an example of the use of the Parametric Map IOD to encode Ktrans for a Dynamic Contrast Enhanced (DCE) MR.

The frames comprise a single traversal of a regularly sampled 3D volume, described as a single stack and a single quantity, with dimensions of Stack ID, In-Stack Position Number and Quantity. A reference is also provided to the (single entire multi-frame) MR image from which the parametric map was derived. Only the Frame Content Sequence and Plane Position Sequence vary per-frame; all other functional groups are shared in this example.
