 | PostLabelingDelay                 | REQUIRED                                                      | [number][] or [array][] of [numbers][] | This is the postlabeling delay (PLD) time, in seconds, after the end of the labeling (for `(P)CASL`) or middle of the labeling pulse (for `PASL`) until the middle of the excitation pulse applied to the imaging slab (for 3D acquisition) or first slice (for 2D acquisition).  Can be a number (for a single-PLD time series) or an array of numbers (for multi-PLD and Look-Locker). In the latter case, the array of numbers contains the PLD of each volume, namely each `control` and `label`, in the acquisition order. Any image within the time-series without a PLD, for example an `m0scan`, is indicated by a zero. Based on DICOM Tags 0018,9079 `Inversion Times` and 0018,0082 `InversionTime`. |
