Abstract
The goal of this study was to compare volumetric analysis in computed tomography (CT) with the length measurement prescribed by
the Response Evaluation Criteria in Solid Tumors (RECIST) for a system with known mass and unknown shape. We injected 2 mL to
4 mL of water into vials of sodium polyacrylate and into disposable diapers. Volume measurements of the sodium polyacrylate powder
were able to predict both mass and proportional changes in mass within a 95 % prediction interval of width 12 % and 16 %,
respectively. The corresponding figures for RECIST were 102 % and 82 %.
