This article, published in the Journal of Neurological Surgery, explores the feasibility of using noninvasive MRI techniques to assess cerebrospinal fluid (CSF) dynamics in patients after skull base tumor surgery. The study involved two patients who underwent skull base tumor resection, and their postoperative MRIs were analyzed using a diffusion-based technique called intravoxel incoherent motion (IVIM) imaging. The results showed that IVIM imaging could potentially identify patients with abnormal CSF dynamics and may reflect the function of the glymphatic system. This technique shows promise for future investigations into postoperative CSF-related complications. [Extracted from the article]
