Quality Assurance in Mammography : The Role of the Radiological Technologists

Abstract

For the early detection of nonpalpable breast cancer, X-ray mammography is being considered as a breast cancer screening procedure. High-quality mammography screening requires stable and high-quality images which can display microcalcifications and low-contrast tissue structures with the minimum patient dose. To meet this requirement, mammography facilities have to use radiographic equipment specifically designed for mammography and to optimize the performance of the equipment (e.g., X-ray mammography unit, screen-film combination and film processor) and radiographic technique (e.g., patient positioning and breast compression). In order to achieve the required quality levels, facilities must establish and maintain quality assurance (QA) programs.
In addition, radiological technologists are required to master mammographic techniques and quality control (QC) methods before performing mammographic procedures, and must continue to make efforts to improve their radiographic techniques by participating in training and medical conferences related to mammography.
Finally, we propose that the Japan Association of Breast Cancer Screening establishes education programs related to mammography.
