Goal of our study was to evaluate high-resolution 3D
multifrequency MRE in patients with newly diagnosed
intracranial tumors. We included 26 patients (6313
yrs., 18 female), the majority of whom had a primary
brain tumor, followed by cerebral metastasis and
meningioma and in one case an intra-axial abscess.
Meningiomas were found to be clearly stiffer and higher
viscous than all other lesions. Grade II-III tumors
seemed to be stiffer and higher viscous than grade IV
tumors and cerebral metastases.
