With the advent of the much less invasive CT and MRI brain scans, the importance of the lumbar puncture as a diagnostic or treatment tool has greatly declined. It is now especially used for the evaluation of infectious, malignant or immunological disorders. It also has been used to evaluate suspected hydrocephalus through serial taps and CSF drainage.
