Total and intraabdominal fat distribution in preadolescents and adolescents: measurement with MR imaging.

abstract：:The x-ray photon energies that give the highest signal-to-noise ratios per unit of exposure or average dose in mammography are significantly greater than those used in current film/screen systems. Optimum photon energies for detection of calcifications in a range of thicknesses of water and fat were calculated. Soft-t...
