Various imaging features were examined, including tumor size, shape (lobulated or round), base width (narrow or broad), presence of cystic necrosis, calcification, signal intensity on T1- and T2-weighted MRI, intravascular flowing-void signs, peritumoral edema, CT attenuation values on non-enhanced and enhanced scans, and adjacent bone destruction. Chi-square tests, t-tests, ROC curves, and multivariate logistic regression were used to establish predictive models.
