Image Quality and Mean Glandular Dose in Mexican Mammography Services Measured with an Object-Insert/TL Mammography Kit

摘要

Thirty mammography systems were evaluated using an Object-Insert/TL kit (composed of an image quality and a dosimetric phantom) to assess image quality and mean glandular dose. All systems complied with the minimum score for object visibility in the image phantom, but most of the images showed artifacts. The average of the mean glandular dose was 1.7±0.7 mGy, and three systems delivered doses higher than the 3 mGy reference value. A weak correlation was found between image quality and dose, possibly reflecting the lack of quality control in the evaluated equipment.
