We used a single-shot accelerated volumetric Arterial Spin Labeling (ASL) sequence to study brain connectivity in regions where resting-state (rs) BOLD analyses can be challenging due to low signal to noise ratio (SNR). Thus, we chose to study the medial prefrontal cortex, part of the default-mode network (DMN), and the subcallosal cortex for which RS-BOLD is impacted by susceptibility artifacts. We also studied the connectivity of the intracalcarine cortex because it belongs to a network involving deep nuclei, for which BOLD signal is reduced due to low blood volume.
