Role of ultrasound in dense breast tissue [Bi Rads breast density category 3-4] on mammogram

ABSTRACT

To assess the role of high resolution ultrasound to find breast masses undetectable on high quality mammography in women with radiologically dense breast tissue [BI RADS category 3-4] on mammogram. Analytical study. PNS Shifa hospital Karachi, from 1[st] October 2004 to 30[th] June 2005 Hundred women were enrolled into the study. All these patients had BI RADS breast density category 3 and BI RADS breast density category 4 on mammogram and they were negative. The age range of patients was 30-60 years with mean age of 45 years. Out of 100 patients, 78 were related with HRT group and 22 patients with breast abnormality group. On ultrasound 58 patients had normal ultrasound [45 from hormone replacement therapy-HRT group and 13 from breast abnormality group.] as well as negative mammogram; remaining 42 patients were abnormal on ultrasound [33 from HRT group and 9 from breast abnormality group]. Ultrasound can find unsuspected, mammographically occult masses especially in dense breast [[BI RADS category 3-4] on mammogram
