Comparative study of mean Glandular dose between two Mammography Systems with Similar Target - Filter Combination

Mean Glandular Dose is a tool for optimization of the mammography parameters which ultimately helps to determine limits for the breast dose and a better understanding of cancer risk. The objective of this study was to compare the Mean Glandular Dose (MGD) between a Full-Field Digital Mammography system and a Computed Radiology system both using the same fixed target/filter combination with automatic exposure mode. The study was also carried out to determine the MGD using the American College of Radiology Mammography Accreditation Phantom (ACR MAP). The mean glandular dose was measured for a breast phantom of thicknesses (20, 30, 40, 45, 50, 60, and 70) mm for the two mammography units and found to be within the acceptable limit. The MGD of the ACR MAP of thickness 42 mm was found to be 1.44mGy and 1.36mGy when exposed at 28kVp for the two units and were within the acceptable limit of less than 3.00 mGy. Comparatively, the doses delivered by the Full-field Digital mammography equipment were higher than doses delivered by the Computed Radiology equipment. It is recommended that both mammography units should be continually used for mammography examination.
