Abstract

Objectives: To study breast density patterns on mammography� in local population, to analyse the need for supplemental screening by high resolution ultrasound of both breasts, to compare obtained density patterns with other populations and finally to contribute my data to the authorised baseline data.

Materials and Methods :Female patients above age 30 years who are referred to department of Radiology, Prathima Institute of Medical Sciences, for mammography on senographe DMR model of GE MAMMOGRAPHY machine of 0.5mm Pb equivalent thickness,40 to 100 mA range, grid ratio of 30:1.These patients were evaluated for density patterns according to BIRADS lexicon , fifth edition and were subjected to high resolution ultrasound breast on Phillips Affinity 70 ultrasound machine . Patients belonging to the local population and are chosen between the study period of June 2016 to January 2017 and of sample size 50 .

Results :A total number of 50 patients who were subjected to mammography and high resolution ultrasonography of both breasts, 44% of our study group had dense breasts( among which 14%had heterogeneously dense breasts and 8% had extremely dense breasts),56%had non dense breasts( among which 24%had fatty breast and 16% had scattered fibroglandular breasts) according to BIRADS Lexicon of fifth edition.Among these dense breasts( of total 44%) 54.54% of them were negative for any kind of lesion on mammography but ultrasound showed positive findings in them.

Conclusion ::The results of our study group suggest that in woman with dense breast pattern on mammography , more than half of them are negative for any kind of lesion may it be benign or malignant on mammogram, where ultrasound displayed positive findings.Hence supplemental screening with ultrasound is also an option adjunct to mammography.
