Synopsis

Keywords: Tumors, PerfusionThe goal of this study was to assess the feasibility of pseudo-continuous arterial spin labeling (pCASL) at 7T on patients with intracranial tumors. We found that 7T ASL imaging was feasible and had a higher resolution than 3T ASL imaging and therefore, may enable in vivo assessment of subtle changes and provides a valuable tool for early detection and mechanism investigation of neurovascular function impairments in patients with intracranial tumors.
