Role of computed radiographic mammography in diagnosis of breast cancer

Comparative study between conventional mammography (MMG) and computed radiographic mammography (CR-MMG) was performed. In detection of mass density, there was no significant difference between them. But some cases revealed poor visualization of fine spicules around the mass density and no obvious contrast difference between the mass density and non-cancer background breast density. However, these cases were diagnosed by alternative compression spot or magnification CR-MMG. In detection of microcalcification, magnification CR-MMG depicted very fine microcalcification not detected on MMG and contact CR-MMG. On routine use of CR-MMG, compression spot or magnification CR-MMG is mandatory. (author)
