RESUMEN
Introduction: Breast USG is an established and accurate tool for the primary evaluation of breast lumps and pathology. It also compliments X- ray mammography in further evaluation and characterization of breast masses and thus avoids surgeries in benign breast diseases and pathology. Method: For USG examination of the breast lumps, a linear-array transducer of 5-7 MHz frequency is required with a good resolution machine. Results: We present a pictorial essay on the role of USG in evaluation and characterization of various breast lumps and pathology. Conclusion: Breast sonography considerably improves the visualization and evaluation of lumps in mammographically radiodense breasts and helpful in the characterization of it, either as solid or cystic lesion. It also improves the specifi city of X-ray mammography when used as an adjunct to it. It is also helpful in guiding FNAC/biopsy from the breast masses.
