  1. Mammography # 1 Week 2

  2. Mammography Facts • 1 in 8 women who live to 95 will develop breast cancer • Most common malignancy in women, only lung cancer kills more women • One of the most treatable cancers • Before Mammo fewer than 5% of pt’s survived 4 years after diagnosis with a 80% recurrence • With a radical mastectomy survival increased to 40% with a 10% recurrence

  3. Goal of Mammography • Detect cancer before it is palpable • Early detection, diagnosis and treatment is the key to a favorable prognosis

  4. How would your family feel with you missing from the family picture?

  5. How would you feel about your father, brother or mother missing from the family picture?

  10. Anatomy of the Breast • Vary in shape & size • Cone shaped with the post surface (base) overlying the pectoralis & serratus muscles • Axillaries tail extends from lat. base of the breasts to axillaries fossa • Tapers ant. from the base ending in nipple, surrounded by areola

  11. Female Breast • Consists of 15-20 lobes • Divide into several lobules • Lobules contain acini, draining ducts and interlobular connective tissue. • By teenage years each breast contains hundreds of lobules

  12. Lymph Nodes • Lymphatic vessels of the breast drain laterally and medially • Laterally into the axillary lymph nodes (C & D) • 75& drain toward axilla • Medially into the mammary lymph nodes • 25% toward mammary chain (F)

  13. Quadrants of the Breast

  14. 3 Tissue Types

  15. Breast Changes with Age

  16. Breast Classifications

  17. Fibro-glandular Breast • Fibro-glandular • Dense with very little fat • Females 15-30 years of age • Or 30 years or older without children • Pregnant or lactating

  18. Fibro-fatty Breast • Fibro-fatty • Average density • 50% fat & 50% fibro-glandular • Women 30-50 years of age • Or women with 3 or more children

  19. Fatty Breast • Fatty • Minimal density • Women 50 and older (postmenopausal), men and children

  20. Positioning

  21. Various Mammographic Positioning

  22. Ouch! Why Compression? • Two Reasons: • Decrease thickness of breast tissue • Reduce OID

  23. Cranio- caudad :CC

  24. Diagram of Proper CC Positioning

  25. CC Images

  26. Multiple Bilateral Benign Calcifications

  27. Breast Cancer

  28. Carcinoma

  29. Microcalcifications

  30. CC positioning • CR Perpendicular • Film tray brought to level of inframammary crease • Wrinkles and folds smoothed out • Compression applied • Markers on axillary side

  31. CC Criteria • No motion • Nipple in profile • All pertinent anatomy demonstrated • Dense areas penetrated • High contrast & optimal resolution • Absence of artifacts • Marker & patient ID visible

  32. Medio-lateral Oblique:MLO

  33. MLO Diagram for Proper Positioning

  34. MLO Properly Positioned

  35. Bilateral MLO

  36. MLO positioning • CR & cassette (IR) angled 45 degrees • Top of cassette (IR) at axilla • Compression applied • Nipple in profile • Marker at axilla

  37. MLO criteria • No motion • Pectoral muscle to level of nipple visualized • Breast pulled away from chest wall • Nipple in profile • Dense areas of breast penetrated • High contrast & optimal resolution • Absence of artifacts • Marker & PT ID visible

  38. What position is this?

  39. What position is this?

  40. Breast ImplantsAre they worth it?

  41. Complication with Breast Augmentation • Mammography has a 80-90% true positive rate for detecting breast cancer in those women without implants • Decreases to 60% with implants • Because 85% of breast tissue is obscured • More images are needed than the standard two projections • There is a risk of rupturing the implant

  42. Elkland Method for Imaging with Breast Implants

  43. Image ComparisonWhich is the Push back (Elkland)?

  44. Male Mammography and Cancer

  45. Male Mammography • 1300 men get breast cancer per year • 1/3 die • Most are 60 years or older • Nearly all are primary tumors • Symptoms include: • Nipple retraction • Crusting • Discharge • Ulceration

  46. Gynemastia • Benign excessive development of male mammary gland • Occurs in 40% of male cancer pt’s • Survival rates with treatment are 97% for 5 years
