  1. BREAST SONOGRAPHY Maya Cohen M.D Rabin Medical Center Radiology

  2. 2006 • Serve as “Second look tool” to guide • biopsies to lesions diagnosed by MRI

  3. Valid Role of Breast US Cysticversus solid determination

  4. Valid Role of Breast US Evaluation of mass not visible with mammography Due to density or location

  5. Valid Role of Breast US Evaluation of an infectedbreast For abscess

  6. Valid Role of Breast US Evaluation of an asymmetric density Picked by mammography

  7. Reportingsonography results • BIRADS SCORE • Breast imaging reportingand data system

  8. LEXICON • BACKGROUND • ECHOTEXTURE • MASS • SHAPE • ORIENTATION • MARGIN • LESION BOUNDARY • ECHO PATTERN • POSTERIOR ACOUSTIC FEATURES • SURROUNDING TISSUE

  9. location • No lexicon for location • What to describe: • Side • Clockface • Concentric rings • Radial/ Antiradial

  10. Location in the breast

  11. Radial/Anti- radial Radial Anti-radial

  12. Location In the Breast AX C AX B A Distance from nipple CLOCKFACE

  13. MASS Occupies space Should be seen in two different projections

  14. Background Echotexture • Breast tissue Variable • Homogenous-Fat • Homogenous-Fibroglandular • Heterogenous

  15. MASS • Occupies space • Should be seen in two different projections

  16. Mass -Margin • Circumscribed • Not Circumscribed: • Ill defined • Angular • Microlobulated • Spiculated

  17. Mass –Echo Pattern • Anechoic • Hyperechoic( relative to FAT) • Complex( heterogenous) • Hypoechoic • Isoechoic

  18. Mass Surrounding Tissue • Architectural distortion • Skin Thickening (Normal-2 mm) • Skin Retraction • Edema (Inflammatory Ca., radiation, mastitis,CHF )

  19. BIRADS ASSESSMENTCATEGORIES • O Needs further investigation • 1 Negative • 2 Benign Findings • 3 Probably benign • 4 Possibly malignant • 5 Highly suggestive of malignancy • 6 Known- biopsy proven malignancy
