Accelerated dynamic ASL with model-based reconstruction, single-shot 3D spiral k-space trajectories and background suppression. With a scan time of 60 s / OT measurement, the model-based reconstruction reduced the background noise and model residual (mean residual = 4.6e-6), compared with conventional gridding reconstruction (mean residual = 7.1e-6). The proposed method maintained the image quality with a scan time of 40 s / OT (mean residual = 5.7e-6) and provided moderate image quality with a 20 s / OT measurement (mean residual = 9.5e-6). Units: Dynamic model fitting residual (a.u.). CBF maps (ml/100g/min). ATT maps (seconds).
