Description
Summary:•Crossed cerebellar diaschisis (CCD) was observed in glioma patients after treatment.•ASL-CBF and DSC-rCBF maps are better at diagnosing CCD than DSC-rCBV or DSC-Tmax maps.•Presence of CCD is associated with supratentorial lesions involving the corona radiata, basal ganglia, and insula. To assess crossed cerebellar diaschisis (CCD) in post-treatment glioma patients, and to compare the performance of arterial spin labelling (ASL) and dynamic susceptibility contrast (DSC) in detecting CCD. This retrospective study included 130 patients who had both DSC and ASL. Among them, 16 had underwent fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). We investigated the relationship between CCD and the location and size of supratentorial lesions, and compared PET diagnostic performance with that of ASL and DSC. We assessed the inter-methods agreement for ASL and DSC, and performed quantitative analysis by calculating the asymmetry index (AI) between bilateral cerebellum and exploring how the AI values for ASL-CBF, DSC-rCBF, and DSC-rCBV maps correlated with each other.
