Differentiation of the Intradural Extramedullary Spinal Tumors, Schwannomas and Meningiomas, Utilizing the Contrast Ratio as a Quantitative Magnetic Resonance Imaging Method

Schwannomas and meningiomas are the most common intradural extramedullary spinal tumors; however, differentiating between them using magnetic resonance imaging (MRI) is a frequent challenge. In this study, we aimed to investigate using the contrast ratio (CR) as a quantitative MRI method in the differentiation of schwannomas and meningiomas.
