Perfusion and functional MRI, yielding markers such as cerebral blood volume, cerebrovascular reactivity, and functional connectivity, play an important role in the diagnosis and treatment of brain tumors. However, a major limitation is that collection of all this information requires separate scans and, in some cases, separate visits. Here we applied a novel iVas-MRI technique that provides quantitative assessment of multiple hemodynamic parameters and functional connectivity in a single scan of 9 minutes. It was found that the multi-parametric maps can reliably differentiate tumor from normal tissue and can further predict tumor grade.
