RESUMEN
As part of the physico-technical quality assurance of the German breast cancer screening program, the threshold contrast visibility and the average glandular dose of every digital mammography system have to fulfill the requirements of the "European guidelines for quality assurance in breast cancer screening and diagnosis" (4th Edition). To accomplish uniform measurements in all federal states of Germany, the physical board of the reference centers developed a special guideline in 2009. Due to recent changes in the guidelines and standards, a second version of the guideline was developed by the reference centers. This guideline describes the determination of the average glandular dose as well as the CDMAM image acquisition and the CDMAM image evaluation. The determination of the threshold contrast visibility can be performed visually or automatically. The determination of the average glandular dose is based on DINâ6868â-â162 and the threshold contrast visibility test is based on the German "Quality Assurance Guideline".

It is reported on the rare case of a 46-year-old female patient with a bilateral mesothelioma of the pleura without contact to asbest. Although the female was suspected in a malignant tumor and many diagnostic investigations were performed, diagnosis could be ensured morphologically only a short time before her death. Causes and development of mesothelioma, histological types, clinical symptoms and diagnostic procedures are described.
