Overview
MRI scan is more sensitive than CT scan in identifying the complications of bacterial meningitis which include subdural/epidural empyema and pyogenic abscess. Two modalities of MRI which may be more specific for identifying complications may include FLAIR and DWI imaging.
MRI scan
MRI is superior to CT scan to detect the complications of bacterial meningitis such as subdural or epidural empyema and vasculitic complications. FLAIR(fluid attenuated inversion recovery) weighted images may be preffered modality for complications such as subdural or epidural empyema. However, early parenchymal complications and differentiating pyogenic abscess from other ring enhancing lesions caused by other etiologies may be better determined by DWI(diffusion weighted imaging).[1][2][3][4]
