A . Tissue region of interest (ROI) is located at the left orbital gyri. B . The mean of the left and right distal intracranial internal carotid artery. C . Suprasellar CSF is used as reference. D . Pontine CSF is used as reference. E . Adjusted from Qiao et al. 19 F. Currently used in our clinic G . Adjusted from Qiao et al. 19 with a shorter TR. VISTA = volumetric isotropic turbo spin echo acquisition, VIRTA = volumetric isotropically reconstructed turbo spin echo acquisition, PD = proton density, SNR = signal-to-noise ratio, CNR = contrast-to-noise ratio, CSF = cerebrospinal fluid.
