A fully automatic multiparametric radiomics model for differentiation of adult pilocytic astrocytomas from glioblastomas

ConclusionsThe fully automatic combined clinical and radiomics model may be helpful for differentiating adult PAs from HGGs.Key Points•Differentiating adult PAs from HGGs is challenging because PAs may manifest a large spectrum of imaging presentations, often including aggressive imaging features.•The fully automatic combined clinical and radiomics model showed a significantly higher performance than the clinical model or humans.•The model explanation by SHAP suggested that second-order features from T2-weighted imaging were important in diagnosis and might reflect the underlying pathophysiology that PAs have lesser tissue heterogeneity than HGGs.
