Characteristics of typical and atypical meningiomas on ADC maps with respect to schwannomas

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 discrim...

Description
Summary: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.
