In brief: Not usually
These days, MRI films are typically sufficient but LP may be used if diagnosis is unclear

In brief: Yes.
The test is one of many used to diagnose ms.
Even mris of the brain are not specific enough. The diagnosis is a compellation of tests including the lp, x-rays, and clinical presentation.

Revised McDonald criteria allows MRI confirmation with certain patterns, thus making LP redundant in those cases.

You are right, but I would want both. At the time I answered the question, it was not an issue. But thanks for your comment!

In brief: Sometimes
In many cases, the history, examination, and radiological findings are enough to make a diagnosis of ms.
In more borderline cases, however, a lumbar puncture can provide a definitive diagnosis. This is very important, as you do not want to put someone on a potentially toxic medication for a disease they might not have!
