CSF flow scan; Cisternogram
Risks associated with a lumbar puncture include pain at the injection site, bleeding, and infection. There is also a very rare chance of nerve damage.
The amount of radiation used during the nuclear scan is very small, and virtually all of the radiation is gone within a few days. There have been no documented cases of injury or damage caused by the radioisotope used with this scan. However, as with any radiation exposure, caution is advised if you are pregnant or breastfeeding.
You should lie flat after the lumbar puncture (to help prevent headache from the lumbar puncture). No other special care is usually necessary.
