There has been a surging interest in using arterial spin labeling (ASL) MRI to measure cerebral perfusion. Current downloadable ASL analysis toolboxes are still primitive compared those for fMRI and DTI, and involves issues of software compatibility and computational burden. Here we describe a cloud-computing-based tool for comprehensive analysis of ASL-MRI. With this tool, the user can obtain CBF maps and ROI-averaged CBF values without having to install any software on the local computer. The maintenance of software upgrades will be performed by the developer. This tool may prove valuable and timely in accommodating the recent surging interest in ASL-MRI.
