Measurement of peritoneal dialysate volume by CT.
Three-dimensional (3-D) graphic reconstruction of serial image data of x-ray CT on three dialysis patients was studied to measure peritoneal dialysate (PD) volume. Volume estimation with a surface reconstructed model provided a 16% error; a 35% error was found with a voxel model, although the total time required by the voxel model was 15 times less.
