Summary
Regions of edema have lower than normal densities on computerized tomography (CT) scans. This is not due to a change in electrolytes but rather to the dilution effect of increased water content. Regional blood volume measurements can be made by subtraction of a regular CT scan from an infusion scan. Using this method, a decrease in blood volume proportional to the amount of edema has been found. Increased pressure collapsing blood vessels and the simple dilution due to the influx of water account for this relationship.
