Abstract Aim To elucidate correlation between signal intensity on diffusion‐weighted images (SI‐DWI) and clinical backgrounds for uterine adenomyosis and to compare SI‐DWI of adenomyosis and malignant uterine tumors. Methods This study exam…

PURPOSE: Seromucinous borderline tumor (SMBT) is a newly categorized ovarian tumor in the 2014 revised World Health Organization (WHO) classification. SMBT is similar to serous borderline tumor (SBT) on MRI reflecting their pathological fin…

Endometriosis is a common gynaecological condition of unknown aetiology that primarily affects women of reproductive age. The accepted first-line imaging modality is pelvic ultrasound. However, magnetic resonance imaging (MRI) is increasing…

Background Although age-related change of junctional zone (JZ) of the uterus has been known, there has been no previous systematic study of age-related changes of uterine peristalsis that is observed as the wave conduction of the thickest o…

OBJECTIVES: To assess the detectability of a low-signal-intensity line within adenomyosis lesions adjacent to the endometrium on apparent diffusion coefficient (ADC) maps, and to establish correlations between these lesions and their possib…

BACKGROUND: Uterine peristalsis is supposed to be closely related to the early stages of reproduction. Sperms are preferentially transported from the uterine cervix to the side of the tube with the dominant follicle. However, with respect t…

PURPOSE: To evaluate the ability of automated software to quantify uterine peristalsis on cine magnetic resonance imaging (MRI). MATERIALS AND METHODS: At 1.5T, half-Fourier acquisition single-shot turbo spin echo (HASTE) techniques were us…

PURPOSE: The purpose of the study was to investigate the magnetic resonance imaging findings of decidualized endometriotic cysts in comparison with endometriotic cysts associated with ovarian cancers. METHODS: Eighteen decidualized endometr…

PURPOSE: To determine the optimal single shot fast spin echo (SSFSE) technique by varying interval between image acquisitions for cine MRI of uterine peristalsis. MATERIALS AND METHODS: MRI was performed in 13 premenopausal women (4 normal …

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…

The inherent contractility of the uterus has attracted concern of researchers and exhibits two known patterns of contraction. One is focal and sporadic bulging of the myometrium, and the other is rhythmic and subtle stripping movement in th…

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…

Adenomyosis is a nonneoplastic condition, characterized by benign invasion of ectopic endometrium into the myometrium with hyperplasia of adjacent smooth muscle. The common symptoms include dysmenorrhea, menorrhagia, and abnormal uterine bl…
