Automatic planning for regional perfusion imaging

Regional Perfusion Imaging (RPI) is a method allowing imaging of individual perfusion territories from major feeding arteries that could become a valuable clinical tool for evaluation of patients with cerebro-vascular disorders. Careful planning of the inversion slab is a prerequisite for correct estimation of regional perfusion. So far, manual planning using MR angiography sequences was used for correct positioning of the labeling slabs. However, due to tortuous vascular anatomy, such manual planning is time consuming and very operator dependent. Here, we propose a fast method for automatic planning requiring only minimal user input using processing of TOF images.
