Abstract

Meningioma brain tumors constitute the majority of adult primary brain tumors, in which the role of apparent diffusion coefficient (ADC) is controversial. We hypothesize that analysis of the heterogeneity within a tumorous ecological region can reveal biological tissue properties, which could further assist decision making about the optimum patient-specific treatment strategy. In the present work, we propose an automated computer-aided diagnosis method for phenotyping meningioma brain tumors, based on features representing spatial heterogeneity in ADC-maps, with classification accuracy of 85.1%. In conclusion, it is demonstrated that heterogeneity of meningioma brain tumors can be a potential discriminating biomarker of tumor malignancy.
