2. Endometerium: 1. US is first choice 2. MRI: diagnosis and staging of malignancies * MR-features do not diagnose endometrial polyps from cancer!?

3. 1- Benign lesions Congenital UT disorders, leiomyomas, polyp, hyperplasia, adenomyosis, endometeriosis,cystic teratomas

7. Endometrial atrophy

8. UTERINE PERISTALSIS

10. DIDELPHYS

11. BICORNUATE

12. Mimics of Bicornute Uterus

13. SEPTATE

15. COMPLEX ANOMALIES

19. 2-Malignants: endometrial cancer (early, late, recurrence), sarcoma, adenosarcoma, mixed mesodermal, neoplasms, liomyosarcoma, lymphoma, choriocarcinoma, metastasis

21. ENDOMETRIAL CANCER, EARLY STAGE

22. ENDOMETRIAL THICKENING

23. ENDOMETRIAL POLYP ADENOMYOSIS

24. ENDOMETRIAL CANCER, LATE STAGE

26. ENDOMETRIAL CANCER, RECURRENCE

27. DDx: Endometrial Carcinoma Recurrence Post-surgical granuloma

29. ENDOMETRIAL CANCER, RECURRENCE

32. ENDOMETRIAL STROMAL SARCOMA

33. ADENOSARCOMA

34. Uterine masses Endometrial polyp Endometrial cancer

35. MALIGNANT MIXED MESODERMAL TUMOR

36. LYMPHOMA, UTERUS

37. Choriocarcinoma,uterus

38. DDx: Choriocarcinoma Molar pregnancy Retained products of conception

39. Metastases, uterus

54. 3-Others: adenomyosis, asherman, cystic adenomyosis, tomoxifen, induced changes, IUCD, age and hormonal changes

55. ADENOMYOSIS

58. Cystic adenomyosis

59. Hemorrhagic leiomyoma Gartner duct cyst

61. INTRAUTERINE DEVICE EVALUATION

62. TAMOXIFEN-INDUCED CHANGES

63. Endometerium: 1. Proliferatine 3-8 mm 2. Secretary 5-16 mm 3. Menopause a. No bleeding = 8 mm b. With bleeding = 5 mm 4. Atrophic > 4 mm

64. MRI of endometrium: T1 intermediate signal T2 high signal STIR, MR-myelogram high signal * UT peristalsis signal ↓, thickness change

65. Conclusion: *MR-features do not accurately distinguish endometrial polyps from cancer because images limited to T2 signal and T1 anatomy *For congenital anomalies 75-100% accuracy *Can be use for diethylbestrol exposure (hyperplasia, T-shaped, UT, endometrial constriction, hydrosalpinges and short cervix)
