 | FlipAngle        | RECOMMENDED, but REQUIRED for Arterial Spin Labeling in case `LookLocker` is set `true` | [array][] of [numbers][] | Flip angle (FA) for the acquisition, specified in degrees. A single value applies to all volumes, or an array provides a value for each volume. Corresponds to: DICOM Tag 0018, 1314 `Flip Angle`. 4D files with variable FA should only be used when volume timing is critical for interpretation of the data, as in ASL or variable FA fMRI sequences. |
-| NegativeContrast | OPTIONAL                                                                                | [boolean][]              | `true` or `false` value specifying whether increasing voxel intensity (within sample voxels) denotes a decreased value with respect to the contrast suffix. This is commonly the case when Cerebral Blood Volume is estimated via usage of a contrast agent in conjunction with a T2\* weighted acquisition protocol.                               |                      |
