introduction one of the best methods in the diagnosis and control of breast cancer is mammography. the importance of mammography is directly related to its value in the detection of breast cancer in the early stages, which leads to a more effective treatment. the purpose of this article was to calculate the x-ray spectrum in a mammography system with monte carlo codes, including mcnpx and mcnp5...

RATIONALE AND OBJECTIVES Diagnostic mammography is performed on women with clinical symptoms that suggest breast cancer or women for whom further mammographic evaluation has been requested because of an abnormal screening mammography. We assessed whether the use of full-field digital mammography would improve the positive predictive value (PPV) for the diagnosis of breast cancer in a diagnostic...

BACKGROUND Digital mammography is slowly replacing screen film mammography. In digital mammography, 2 methods are available in acquiring images: digital storage phosphor plate and full-field digital mammography. The aim of this study was to compare the image quality acquired from the 2 methods of digital mammography in the detection of breast cancer. METHODS The study took place at the Nation...

From 03/2009 to 09/2009, 50 patients underwent digital Full Field Mammography (detector: resolution 70lm) (Fa. Siemens) and, after diagnosis and preoperative wire localization, digital Full Field Mammography (detector: resolution 50lm) (Fa. FujiFilm) with the same exposure parameters. Five investigators retrospectively determined the diagnosis after the operation from randomly distributed medio...
