Türk Nöroradyoloji Derneği 30. Yıl Uluslararası Katılımlı Tanısal ve Girişimsel Nöroradyoloji, Baş-Boyun Radyolojisi Kongresi, İstanbul, Türkiye, 17 - 21 Şubat 2021
Objective: To assess the diagnostic efficiency of apparent diffusion coefficient (ADC) values in differentiating schwannomas and meningiomas
of the posterior fossa.
Materials and Methods: A total of 56 patients who referred for MRI of
posterior fossa extra-axial lesions were retrospectively enrolled in our
study. The mean ADC values of the tumor and reference value from
contralateral cerebellar parenchyma obtained by using ROI from ADC
maps by two radiologists in consensus. ADC ratios were calculated.
Differences between schwannomas and meningiomas in mean ADC,
ADC ratio values were statistically analyzed.
Results: 52.7% of patients were male, 47.3% were female with a mean
age of 53.4. Based on conventional MRI features, 29 was interpreted as
schwannoma, 26 as meningioma. Mean ADC values (x10-3 mm2 s-1)
