BackgroundDifferentiating ovarian endometriomas from hemorrhagic cysts matters because their management differs.PurposeTo evaluate whether a multiparametric magnetic resonance imaging (MRI) approach improves differentiation of endometriomas…

BACKGROUND: Identifying and locating endometriotic lesions is crucial for preoperative planning, so new magnetic resonance imaging (MRI) techniques are urgently needed to improve the diagnostic sensitivity for pelvic endometriosis. PURPOSE…

BACKGROUND: There are different types of computed tomography (CT) contrast enhancement patterns of the uterus. It is not known whether these are hormonally dependent. PURPOSE: To assess the relationship between these patterns and the menst…

BACKGROUND: Endometrioma is a common manifestation of endometriosis that can be difficult to diagnose with conventional magnetic resonance imaging (MRI). Susceptibility-weighted imaging (SWI) may be more sensitive than conventional MRI in t…

BACKGROUND: In magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) treatment of uterine fibroids, the immediate ablation response is significantly affected by blood perfusion. The variability of measurement for blood perfu…

BACKGROUND: Treatment of female pelvic malignancies often causes pelvic nerve damage. Magnetic resonance (MR) neurography mapping the female pelvic innervation could aid in treatment planning. PURPOSE: To depict female autonomic and somati…

Background Hysterosalpingram (HSG) evaluation of tubal patency is typically performed in the follicular phase, but data to support this timing are lacking. Purpose To determine whether menstrual cycle phase or hormonal treatments affect obs…

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…

BACKGROUND: The classic magnetic resonance imaging (MRI) feature of endometriomas is the shading sign, which is characterized by T2-shortening in ovarian cystic lesions that are hyperintense on T1-weighted images. The shading sign is infreq…

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…

BACKGROUND: Knowledge of the precise sites of deep infiltrating endometriosis (DIE) lesions is essential for preoperative workup and treatment. Susceptibility-weighted imaging (SWI) has high sensitivity for blood products and have recently …

Several imaging options are available today to diagnose endometriosis. Currently, the two techniques most used are sonography and magnetic resonance imaging (MRI). Three-dimensional (3D) sonography has proved to be particularly sensitive in…

BACKGROUND: Previous literature demonstrated that the T2* value of the uterine junctional zone was lower than that of peripheral myometrium by using BOLD MR imaging. We expect T2* mapping image may add more information to T2-weighted images…

Abdominal wall endometriosis is unusual and mostly occurs in scars following Cesarean section. Although malignant transformation is rare, it must be recognized in order to benefit from radical resection. We report a very rare case of mixed …

BACKGROUND: Magnetic resonance imaging (MRI) is a promising technique in the study of endometriosis, allowing a complete mapping of lesions before surgery. However, the value of MRI in the diagnosis of endometriosis in the bladder, in super…

BACKGROUND: Magnetic resonance (MR) imaging has been established as the best imaging modality for the detection, localization, and staging of uterine cancers. Recently, the usefulness of diffusion-weighted imaging (DWI) in the diagnosis of …

PURPOSE: Pelvic congestion is diagnosed by transuterine venography, an invasive procedure requiring sedation and irradiation. Ultrasound may be an alternative but is hindered by slow flow within pelvic veins. In an attempt to counter this, …

Thoracic endometriosis is an uncommon disorder. In most cases, the diagnosis is based on history alone and radiographic findings depend on the menstrual cycle. CT findings include ill-defined or well-defined opacities, nodular lesions, cavi…
