DeepASL (DLASL) Pipeline
========================

**Runner:** ``pyasl.pipelines.dlasl_pipeline.run_dlasl_pipeline``

**Purpose.** Minimal two-step DeepASL flow:

1. ``DLASLBuildMask`` — build a (resampled) mask from tissue segmentations
2. ``DLASLDenoiseCBF`` — denoise CBF volumes with a dilated CNN
