We agree with the author's comments in the correspondence section. Patel et al., have mentioned about the echo planar imaging (EPI) based arterial spin labeling (ASL) sequence, which is associated with a low signal-to noise ratio (SNR), lower temporal and spatial resolution and greater susceptibility artefacts. In our study, we have used pseudo-continuous arterial spin labeling sequence incorporated with volumetric fast spin-echo readout [3D PCASL] (3T GE HDXT), which is a fast spin echo (FSE) based readout and gives better SNR, fewer susceptibility artefacts and better labeling efficiency as compared to other available ASL techniques. Our experience with ASL suggests that it can be used in routine clinical practice at the expense of a few extra minutes of imaging. The role of superselective ASL appears to be promising in the near future; however, we do not have any experience with the novel technique
