Relative to the uncorrected-zCBF map, the corrected-zCBF map further refined the distributed brain regions in the PD group versus the HC group, manifested as the extension of motor-related regions (<em>P</em>_FWE &lt; 0.001). Compared to the HC subjects, patients with PD had elevated zATT and zCBV in the right putamen, a shortened zATT in the superior frontal gyrus, and specific zCBV variations in the left precuneus and the right supplementary motor area (<em>P</em>_FWE &lt; 0.001). The corrected-zCBF (AUC, 0.90; 95% confidence interval [CI]: 0.84−0.96) showed better classification performance than uncorrected-zCBF (AUC, 0.84; 95% CI: 0.75−0.92) (<em>P</em> = 0.035). zCBV achieved an AUC of 0.89 (95% CI: 0.82−0.96) and zATT achieved an AUC of 0.66 (95% CI: 0.55−0.77). The integration model of hemodynamic features from MDASL provided improved performance (AUC, 0.97; 95% CI: 0.95−0.98) for the diagnosis of PD by comparison with each perfusion model (<em>P</em> &lt; 0.001).</p></div><div><h3>Conclusion</h3><p>ASL identifies impaired hemodynamics in patients with PD including regional abnormalities of CBF, CBV and ATT, which can better be mapped with MDASL compared to SDASL.
