Purpose
Breast screening has traditionally relied on screen-film mammography but advances in technology have led to the introduction of digital mammography in this setting. Many studies have been published comparing digital mammography and screen film mammography in breast screening in the general population. The results are mixed but generally showed that digital mammography has similar diagnostic accuracy as screen-film mammography.Digital mammography, however, has been shown to be more accurate in women under the age of 50 years, women with radiographically dense breasts, and in pre- and...
Methods and Materials
A comparative study was performed retrospectively on the women at high risk of breast carcinoma screened at our institution. Data was obtained from the database of patients who attended our family history clinic. These women were screened with annual mammography if deemed to be at high risk of breast carcinoma as per guidelines from the National Institute for Health and Clinical Excellence (NICE).The women were screened with screen-film mammography (SFM) in 2004 whereas the women were screened with digital mammography (DM) from July 2007 to...
Results
There were in total 1342 patients in the screen-film mammography (SFM) group and 1978 patients in the digital mammography (DM) group. Some patients were excluded due to missing data. Therefore, the number of patients included in this study was 1178 in the SFM group and 1916 in the DM group.The recall rate in the DM group was higher at 8.7% as compared to 5.8% in the SFM group. 22.8% of the patients recalled in the DM group were in the prevalent screening round whereas 21.7%...
Conclusion
As shown in previous studies in the general screening population, digital mammography has been shown in our study to have similar diagnostic accuracy as screen-film mammography in the screening of patients with familial breast cancer.The cancer detection rates were similar between the digital mammography and screen-film mammography groups.This has, however, led to an increase in the recall rate although this may partly be due to the learning curve in the interpretation of digital images.There was also no significant difference in the needle sampling rates between...
