Breast ultrasound is primary tool for symptomatic breast examination. Mobile ultrasound systems cost over $1,000 and provide high-resolution images. Breast consists of fibroglandular and fatty tissue with varying amounts
Sonography provides real-time breast imaging without radiation. Mammography remains most common breast imaging modality. Sonography helps differentiate cystic from solid masses. Useful for young, pregnant, and lactating patients. Guides breast biopsy and interventional procedures
Breast ultrasound is a useful adjunct to mammography for breast disease diagnosis. High-resolution hand-held transducers provide consistent, reproducible images. Technical advances have improved image quality significantly
Breast calcifications are radio-opaque calcium salt deposits in mammography. Present in ~85% of mammograms, increasing with age. About 19% of calcification recalls result in cancer diagnoses. Up to 50% of breast cancers can be associated with calcifications
DCIS represents 25-30% of breast cancers, 95% diagnosed by microcalcifications. Terminal ductal lobular unit (TDLU) is basic functional breast unit. Most calcifications form within terminal ducts or acini
