Can you tell me the difference between a lumbar puncture and a myelogram?

Injection of dye. They both involve a needle being placed into the spinal canal. In a lp, cerebrospinal fluid is removed from the canal, while in a myelogram a dye is injected into the canal. This dye allows very clear imaging of the spinal cord and nerve roots.
See below. A LP involves withdrawing cerebrospinal fluid for study. A myelogram involves injecting a special dye for evaluation of spinal pathology. The placement and location of the needle are the same for both procedures.
The difference is . That a lumbar puncture is a spinal tap to obtain fluid and measurements of the cerebral spinal fluid while a myelogram is the same procedure but then a contrast material or "dye" is then injected to outline the spinal cord for imaging with x-rays or radiographs and usually followed by a ct scan.

How do a lumbar puncture and a myelogram differ?

Lumbar puncture. The spinal cord has three layers, the dura, arachnoid and the pia. The cerebrospinal fluid is sub arachnoid. A "lumbar puncture" is placing a spinal needle to access the cerebrospinal fluid. A myelogram is a diagnostic procedure usually for spine related pain that requires a lumbar puncture to inject contrast or dye into the cerebrospinal fluid after which an xray and usually ct scan are done.

Myelogram CT with a lumbar puncture 7ds and 2bld patch later it was CSF leak. Myelo showed dual cerv & lumb stenosis. Is it poss CSF crashed my syst?

Not sure. I am not sure of the question. CSF leak after lumbar puncture is not uncommon. It usually takes about a week to heal. Blood patches may help. CSF leak does not cause the showing of spinal stenosis on the myelogram. The stenosis is from degenerative changes. Read more...
CSF. A myelogram and CSF leak does happen but these are not related to the stenosis or causing further problem to your spine. Read more...
No. A post-myelogram headache will not damage your spine. The pathology seen on the study was not caused by the study. Read more...
