We attempted to assess whether a machine-learning model based on texture analysis (TA) could yield a more accurate diagnosis in differentiating malignant haemangiopericytoma (HPC) from angiomatous meningioma (AM). Our sample population consisted of 23 malignant HPCs and 43 AM. We compared the diagnostic ability of three classifiers based on texture features extracted from each modality (T2FLAIR, T1-CE, and DWI) to the classifier based on clinical features from three neuro-radiologists. The T1W-CE classifier performed the best.
