Q-space imaging (QSI) is an extended version of diffusion weighted image technique which can be utilized for observing microstructure of brain in micrometer order. In order to assess whether QSI can differentiate between the two most common extra-axial brain tumors of the posterior fossa, we performed histogram analyses as well as ROC analyses on the q-space data of meningioma and cranial nerve schwannoma (CNSch). We also assessed the apparent diffusion coefficient (ADC) for comparison. As a result, we have shown that mean displacement derived from QSI as well as ADC are able to differentiate meningioma from CNSch.
