Using isotopes, Benabib et al. were able, in 1970 and following the work of Descuns et al., to evaluate the function of a ventricular shunt system be measuring the flow passing through it. The experimental study carried out confirmed the applicability of the method described by Benabib et al. to the Cordis-Hakim valve after substitution of the 131I used by those authors by 99mTc O4. Measurement of flow is valid only if true flow lies between 0.085 ml/mn and 1.7 ml/mn. Although with flow rates of less than 0.07 ml/mn the values obtained are overestimates, the distinction between no flow and slight flow remains definite.
