This study compares single-shot and interleaved constant-density spiral arterial spin labeling (ASL) sequences to their dual-density analogs. Single-shot dual-density parallel spiral ASL reconstructed using the SPIRiT parallel image reconstruction algorithm had the best combination of motion robustness, spatial resolution, and resistance to suceptibility artifacts.
