[Gamma-myelography in neurosurgery].
The gamma-myelography is rapid and riskless investigation whose practice is very easy to perform while doing CSF study. The choice of radioactive tracer in liquid or gaseous phase depends on suspected abnormality. In case of medullar compression, it enables to affirm the diagnosis of block and define its level. It does not enable to know the intra or extradural localization of a lesion. For this reason we often use in the same time a 99mTc stannous pyrophosphates scintigraphy of rachis. Association of these two technics is particularly interesting in case of pressure myelitis due to vertebral metastatic localization. In traumatic pathology, gamma-myelography can be realized in cases of emergency, because of its inocuity and rapidity of its realization (10 min. with use of 133 Xenon).
