SlicePLDAdjust (Preclinical)
============================

**Purpose.** Apply across-slice PLD correction for multi-slice ASL with simple exponential factors.

Context I/O
-----------

- **Reads/Writes:**  
  - If ``relCBF`` exists → adjust it in-place  
  - Else → adjust ``ImageDif`` in-place  
- **Reads:** ``Para`` for slice count if available

Parameters
----------

=================  ===================  ==========================================
Key                Type / Default       Meaning
=================  ===================  ==========================================
``SGap``           float / ``31``       Slice gap (ms-equivalent delay step per position)
``T1blood``        float / ``2800``     Blood T1 (ms) in the exponential factor
=================  ===================  ==========================================
