| Abstract | [Summary] We performed phantom examination to determine CSF flow rate through the ventricular shunt, (Rickham-Holter system and Pudenz system) . The shunt systems operated as siphon under the gamma camera. 99mTcO4- of 50 to 100μCi was injected into the reservoir and removal of it from the reservoir was expressed as a time-activity curve, and clearance half-time (T1/2) of radioactivity was determined from this curve. Increased weight in lower container divided by the duration of the water transfer yielded the flow rate (F) . T1/2 and F were plotted on double-log scale and they showed linear relationship. In Rickham-Holter system, the regression equation was log10(F)=-1.91 log10(T1/2)-0.032 and in Pudenz system it was log10(F)=-1.03 log10(T1/2)-0.02. The data of Pudenz system were as the same as that of Harbert's report. In the case of Rickham-Holter system, however, our results showed that experimental volume (Vexp) changed with flow rate (Table 1) , while Harbert et al. reported that Vexp was constant. Then we re-examined according to Harbert's method using Harvard infusion pump and confirmed that our data were proper. Therefore, the above regression equation for each reservoir should be used to calculate CSF flow through the shunt. |
