To ensure a nerve-sparing radical hysterectomy, a clear neurovascular anatomy of the paracervical area is essential. After isolation of the pelvic splanchnic nerve in the most dorsal side of the cardinal ligament and the hypogastric nerve o…

PURPOSE: Endometriotic cysts are known to transform into ovarian cancers, such as clear cell and endometrioid carcinomas. We hypothesized that an iron-rich environment produced by the repetition of hemorrhage in the endometriotic cysts duri…

Endometriosis is one of the most important causes of infertility; however the precise mechanism by which it affects female fertility is unclear. The objective of this study was to study the functional aspects of the uterus by evaluating ute…

PURPOSE: To prospectively evaluate anticholinergic drug effects on uterine peristalsis and sporadic myometrial contractions, as well as on intestinal motion, with cine magnetic resonance (MR) imaging. MATERIALS AND METHODS: This prospective…

Poster: ECR 2007 / C-319 / MR spectrum of benign endometriomas and malignant transformation in endometriomas: Correlation with pathologic findings by: T. Koyama , K. Tamai, Y. Mikami, N. Morisawa, K. Fujimoto, T. Saga, S. Fujii, K. Togash…

PURPOSE: To evaluate the capability of a newly developed semiautomatic analysis technique for evaluation of uterine peristalsis in comparison with visual assessment. MATERIALS AND METHODS: Cine magnetic resonance (MR) images were obtained f…

PURPOSE: To retrospectively evaluate the accuracy of magnetic resonance (MR) imaging in depicting posterior cul-de-sac obliteration in patients with endometriosis. MATERIALS AND METHODS: Institutional review board approval was not required …

Cine mode magnetic resonance (MR) imaging has allowed evaluation of kinematics of the pelvis. Visualization of dynamic changes under strain facilitates evaluation of prolapses and adhesions between organs. The uterus, an organ of smooth mus…

A clinical case that suggested the involvement of blood coagulation cascades in the inflammation reaction induced by leakage of ovarian endometriotic cysts was encountered. Here, a rapid elevation in plasma D-dimer level (119.6 micro g/ml) …

Diffuse uterine enlargement is a common clinical finding. Because this abnormality can represent a physiologic manifestation, benign tumor, or malignancy, the diagnostic dilemma of a diffusely enlarged uterus can be challenging. Clinical fi…

PURPOSE: To demonstrate and evaluate uterine peristalsis on cine magnetic resonance imaging (MRI) using ultrafast imaging. MATERIALS AND METHODS: Serial MR uterine images (300) were obtained from 15 normal volunteers over four menstrual pha…

This report describes MR findings of müllerian mucinous borderline tumors, pathologically proven to have arisen from endometriotic cysts, in three patients. They were unilocular or paucilocular masses with mural nodules. Cystic components s…

The authors report atypical magnetic resonance (MR) appearances of adenomyosis in three patients. All lesions appeared as ill-defined masses of heterogeneous high intensity. Follow-up MR study performed in two patients revealed a drastic ch…

On magnetic resonance (MR) imaging, the innermost layer of myometrium exhibits distinct low signal intensity and is termed the junctional zone. All previously published MR reports concerning the junctional zone appearance have been based on…

A case of ovarian pregnancy associated with microscopic endometriosis is described. The case satisfied Spiegelberg's four criteria. The associated endometriotic lesion histologically showed prominent decidual change.

This study was designed to investigate whether or not the pelvic peritoneum exhibits a metaplastic process into müllerian-type epithelium using a marker for epithelial differentiation (Ber-EP4 antigen) and markers that indicate müllerian di…

Magnetic resonance (MR) imaging characteristics of adenomyosis were studied in eight women (aged 37-49 years) who underwent hysterectomy, and detailed radiologic/pathologic correlation was conducted in all cases. Adenomyosis produced diffus…
