Fructose-1,6-Bisphosphatase 1 Reduces 18F FDG Uptake in Hepatocellular Carcinoma.

abstract：:Quality control in diagnostic radiography begins with production of predictable exposures. The authors describe a technique which permits determination of the variation of mR/mAs for the entire diagnostic range of times and currents in only about 1 hour. The mR/mAs in newly installed units has been shown to vary by as...
