title: A simple method of evaluating the penetrability of Spitz-Holter drains with the aid of radioisotopes.
abstract: A simple, reliable, and innocuous method is described for evaluating the penetrability of cerebrospinal shunts with the use of 99mTc O4. After introducing 25 muCi of 99mTc O4 in a volume of about 0.2 ml into Rickham's reservoir, series scintigrams in the lateral or AP direction are made with the aid of a Nuclear Chicago Pho Gamma HP Scintillation Camera. The results are in satisfactory agreement with the surgical findings. No complications have so far been observed.
