MR perfusion in a case with the left middle cerebellar peduncle (MCP) low-grade glioma. a Axial T2WI showing left MCP hyperintense lesion. b, c Pre- and post contrast T1WI showing hypointense signal with no post contrast enhancement. d ASL-CBF showing hyperperfusion of the lesion with ASL-rCBF value of 4.76. e, f DSC-CBF and CBV showing isoperfusion with a DSC-rCBF value of 0.9 and DSC-rCBV value of 1.1. Pathologically proven low-grade glioma with ASL not matching with DSC, hyper on ASL and iso on DSC. ASL arterial spin labeling, CBF cerebral blood flow, DSC dynamic susceptibility contrast, CBV cerebral blood volume, r relative, WI weighted imaging
