Abstract

The radiation dose delivered to patients undergoing mammography examination is of utmost importance because of the risk of cancer induction due to the process. In this work, we analyze the dose to 109 patients (214 images) who underwent mammographic examinations with a full-field digital mammography (FFDM) system. Quality control assessment was first performed using the International Atomic Energy Agency (IAEA) Human Health Series 2 and 17 protocol and the European guidelines for quality assurance in breast cancer screening and diagnosis. The results from the quality control test performed indicates that the system is functioning well. The mean glandular dose of patients analyzed shows that 23 out of 109 patients received averaged doses higher than the acceptable level at the same equivalent breast thickness of a phantom. The mammography system at the department is recommended for continuous use for imaging and screening of patients.
