Regional cerebral blood volume is a useful marker for brain tumor evaluation. However, large blood vessels also contribute to high blood volume, which may have nothing to do with tumor angiogenesis. Prior studies focused on multi-parametric methods to remove a blood vessel which is complex to implement and have a lot of assumptions in the automatic identifications. We propose a simple method to identify the regions affect by large blood vessels using a blood flow map generated by a novel deconvolution technique and successfully identifies the blood vessel contribution in the tumor blood volume map.
