Neuroimaging computed tomography

Neuroimaging Radiologic studies of the brain, usually referring to computed tomography (CT) or magnetic resonance imaging (MRI). 

Lumbar puncture is considered mandatory in patients with suspected bacterial meningitis but the procedure can be hazardous with a risk of brain herniation in patients with raised intracranial pressure, and imaging with computed tomography or MRI is recommended for selected patients to detect brain shift. Patients who are in an immunocompromised state, have new-onset seizures, moderate-to-severe impairment of consciousness or signs that are suspicious of space-occupying lesions (e.g. papilloedema - oedema of the optic disk) should undergo neuroimaging prior to lumbar puncture.
