Synopsis

Keywords: Data Acquisition, Arterial spin labellingIn this study, 3D GraSE-pCASL was combined with Compressed SENSE (CS) to accelerate the acquisition time of perfusion images. The results showed that accelerated 3D CS-GraSE-pCASL could provide sufficient perfusion information in half the acquisition time compared to the conventional method. This technique may be useful in the diagnosis of cerebral blood flow disorders especially for pediatric patients and/or patients with cognitive impairments.
