An AP abdomen projection was obtained using 85 kVp at 10 mAs. The resulting image demonstrated excessively low contrast, although the density was acceptable. What new technique could be used to obtain the projection with equal density but higher contrast?

Question

Lowering the kVp (from 85 to 72) increases the contrast of the image. To maintain the same density with a lower kVp, the mAs must be increased (from 10 to 20 mAs).
