Abstract
The differences in apparent diffusion coefficient (ADC) between typical and atypical
meningiomas and schwannomas were investigated, with 41 patients included in the study.
There were no significant differences in ADC values or ADC ratios between typical
and atypical meningiomas. The discrimination between schwannomas and the typical and
atypical meningiomas on ADC maps was reliable, with significant differences in ADC
values and ratios and with the narrow range of ADC values in meningiomas.
