Abstract

The purpose of this study was to evaluate the precision of a technique for shunt measurement and to quantify its relevant influencing factors. Therefore, 10 patients underwent firstly an intraarterial injection of 100 MBq Tc-99m-MAA and secondly a fractionated intravenous injection of 4 x 10 MBq Tc-99m-MAA. Calculations of the shunt volumina were done with Wheeler's algorithm. In addition the relative shunt voluminafor all applications were computed and corrected for (a) tracer retention, (b) biological degradation, (c) physical decay, (d) remaining activities and (e) the combination of (a) - (d). The coefficient of variation was 9.4%. The influence of (a), (b) and (d) was significant and that of (c) not significant. If all influencing factors were ignored (e), no significant differences could be seen, compared to the fully corrected results. Therefore, fractionated shunt scintigraphy is a simple and rapid technique for precisely determining relative shunt volumina in patients under local chemotherapy.
