Abstract

A study on the analysis of the relationship between body mass, compressed breast thickness (CBT), age, and exposure factors on the mean glandular dose (MGD) in mammography X-ray examinations was conducted at the Radiology Department of Dr. M. Djamil Hospital in Padang. The study aimed to analyze the relationship between several parameters and MGD values. The study was conducted using a collection of mammography patient dosimetry data from January to July 2025, comprising 165 data points. The methods used were simple linear correlation and multiple linear regression tests. The results showed that body mass had a positive and moderate relationship with MGD, with a correlation coefficient (r_xy) values ranging from 0,322 to 0,383. CBT had a positive and strong relationship with MGD with an (r_xy) values from 0,566 to 0,574. Age had a negative and very weak relationship with an (r_xy) values ranging from (-0,146) to (-0,037). . Exposure factors had a positive and very strong relationship with MGD with an Multiple R values ranging from 0,993 to 0,995.
