Berndt M, et al. - Given the utility of Magnetic Resonance Imaging (MRI) including diffusion-weighted imaging (DWI) in the diagnosis of intracranial infection, researchers evaluated the accuracy of DWI in the diagnosis of postoperative intracranial infection. All consecutive patients with intracranial infection receiving neurosurgical intervention having had preoperative MRI including DWI were retrospectively evaluated. Findings revealed the limited value of DWI in evaluating postoperative brain infection. In this work, DWI was identified regaining its validity about three months after surgery.
