The aims of this exhibit are: 1. Describe state-of-the-art techniques of MRI for the uterus. 2. Describe recent advances in knowledge to differentiate uterine malignant tumors from benign diseases. 3. Describe the role of MRI in the evaluation of uterine malignancies for fertility-preserving treatments. 4. Discuss how radiologists can use MRI for management of uterine malignancies.

A. State-of-the-art MRI techniques: Diffusion-weighted imaging, 3D TSE sequences, and MR spectroscopy B. Recent advances in knowledge to differentiate malignant tumors from benign lesions B-1. Minimum deviation adenocarcinoma (adenoma malignum) and lobular endocervical glandular hyperplasia (LEGH) B-2. Uterine corpus tumors C. MRI and fertility-preserving options in the management of uterine malignancy C-1. Cervical cancer C-2. Endometrial cancer D. Conclusion

Major teaching points of this exhibit are: 1. State-of-the-art MRI techniques, such as diffusion-weighted imaging, 3D TSE sequences, and MR spectroscopy, are useful for staging and characterizing uterine tumors. 2. Recognizing some characteristic image findings is the key to differentiating malignant uterine tumors from some benign lesions. 3. It is important to know the role of MRI in fertility-preserving surgical procedures for patients with uterine malignancies.
