AB  - Residual radioactive tracer, which may remain in the spinal needle after dose administration for a radionuclide cisternogram, is a problem. Several techniques to avoid this problem are considered. The percentage of dose sequestered in the needle as a function of spinal needle internal volume and initial tracer volume are also calculated.
