Background Information: Endometrial abnormalities are amongst the most common causes of vaginal bleeding and gynecologist visits Imaging is an important part of patient evaluation, and in some instances, is the first step of choice The radiologist plays an important role in diagnosis, follow-up, management, treatment, and the overall clinical decision making process.

Educational Goals/Teaching Points: We discuss the multimodality appearance of normal endometrium at different stage of life and various stage of menstrual cycle on sonography, sonohysterography, hysterosalpingography, MRI, and CT. We also discuss utility and order of imaging modality preference for assessment of various pathologic processes. We briefly consider the clinical literature on these disorders, with an emphasis on treatment methods and associated imaging methods assisting clinicians for treatment. We briefly discuss the use of ultrasound contrast material in other countries for assessment of endometrium based on data present in the literature.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: Pathologies to be discussed include: hypertrophy, atrophy, dystrophy, polyps, postablation changes, various types of neoplasms including common as well as atypical malignancies, cystic degeneration, adenomyosis, retained products of conception, placental site subinvolution, and invasive mole, choriocarcinoma. Imaging techniques to be discussed include ultrasound, CT, MRI, sonohysterography, and hysterosalpingography. We provide a literature review of data obtained in other countries on use of ultrasound contrast material.

Conclusion: After reviewing this exhibit, the viewer will have a comprehensive understanding of how to accurately diagnose endometrial abnormalities with different imaging modalities, and will understand role of the radiologist as part of the clinical team.
