We explored the imaging features of malignant, brain metastasis, and different grades of glioma using Amide Proton Transfer MR Imaging at 3 Tesla. Results showed that The average APT signal intensities of the viable tumor cores in each tissue groups were significantly higher than those of peritumoral edema or normal-appearing white matter. Metastases had not significantly different APT signal intensities than those of malignant, low-grade and high-grade glioma. APT imaging provides additional diagnostic information to characterize brain metastases non-invasively.
