 For PASL, specifying the `PostLabelingDelay` is required.
 `PostLabelingDelay` is the time, in seconds, from the middle of the labeling pulse until the middle of
 the excitation pulse applied to the imaging slab (for 3D acquisition) or first slice (for 2D acquisition).
 Additionally, the `BolusCutOffFlag` field is required,
 which is a boolean indicating if a bolus cut-off technique has been applied.

 When `BolusCutOffFlag` is set true for `PASL`, two additional metadata fields are required:
 `BolusCutOffTechnique` and `BolusCutOffDelay`.
 In this example, the `BolusCutOffTechnique`, which is the name of the technique used for applying a bolus cut-off,
 is QUIPSS-II consisting of only one bolus cut-off pulse.
 The `BolusCutOffDelay` is therefore a number, representing the duration between the end of the labeling and the start of the bolus cut-off saturation pulse, in seconds.
