Decision tree models for dichotomized differentiation of the 5 most common posterior cranial fossa neoplasms: (A) metastasis, (B) hemangioblastomas, (C) pilocytic astrocytoma, (D) ependymomas, and (E) medulloblastomas. In each box (node/leaf), the accurate classification rate (positive predictive value) is expressed as ratios of the most common tumor type per total number of cases fulfilling the criteria. The intensity of the green color reflects the accurate classification ratio. Froaminal extension refers to tumoral extension through the foramina of Luschka and/or Magendie. *The ADC nth refers to the ADC histogram nth percentile value ×10−6 mm2/s; for example, ADC 70th percentile <1,636 × 10−6 mm2/s. **Peritumoral FLAIR hyperintensity width. ***ADC histogram skewness.
