OBJECTIVE: The clinical application of magnetic resonance imaging-guided focused ultrasound (MRgFUS) surgery for treatment of symptomatic uterine fibroids is often limited because of the bowel between the abdominal wall and uterus. If bowel…

OBJECTIVE: The objective of this study was to investigate the efficacy of high-intensity focused ultrasound (HIFU) combined with gonadotropin-releasing hormone agonist or levonorgestrel-releasing intrauterine system (LNG-IUS) in treating dy…

PURPOSE: To evaluate tamoxifen-related endometrial changes in premenopausal female patients with diffusion-weighted magnetic resonance imaging (DWI). METHODS: This prospective study was performed on 71 premenopausal female patients (mean a…

OBJECTIVE: Magnetic resonance imaging (MRI) is an excellent modality for pelvic imaging. The anatomy of uterine cavity and vagina is optimally evaluated when the walls, which may spontaneously be collapsed, are distended. Distension of thes…

OBJECTIVES: Rectosigmoid involvement by endometriosis causes intestinal symptoms such as constipation, diarrhea, and dyschezia. A precise diagnosis about the presence, location, and extent of bowel implants is required to plan the most appr…

OBJECTIVES: The aim of this study was to evaluate the diagnostic accuracy of a specific protocol of computed tomography-colonography with intravenous contrast medium and urographic phase, which combined simultaneously the study of the intes…

OBJECTIVE: The purpose of this article is to review the etiopathogenesis, molecular cytogenetics, histopathology, clinical features, and multimodality imaging features of desmoid fibromatosis. Recent advances in the management of desmoid fi…

OBJECTIVE: This study aimed to evaluate the diagnostic efficacy of T2 dark spot, T2 dark rim, and T2 shading signs on magnetic resonance imaging in the differentiation of endometriomas from hemorrhagic cysts. METHODS: Seventy-two hemorrhag…

Endometriosis (EN) is a common gynecological condition characterized by the presence of functional endometrium located outside the uterine cavity. Sciatic nerve (SN) is rarely affected by EN. Magnetic resonance imaging allows a direct visua…

OBJECTIVE: The aim of this study was to describe magnetic resonance imaging findings of newly categorized ovarian seromucinous tumors. METHODS: We retrospectively reviewed the images of 29 patients with seromucinous tumor for the following…

OBJECTIVE: We wanted to assess the diagnostic value of computed tomographic colonography (CTC) in recognizing bowel endometriosis in comparison with serum Ca125, transvaginal sonography (TVS), and presence of intestinal symptoms. METHODS: …

We present a case of ovarian torsion in pregnancy with demonstration of vascular flow on sequential Doppler ultrasonography. Magnetic resonance imaging demonstrated ovarian enlargement and edema. Mild symptoms and low clinical suspicion, in…

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 endomet…

OBJECTIVE: We wanted to assess the diagnostic value and morphologic feature of deep infiltrating endometriosis (DIE), involving rectosigmoid colon, with computed tomography (CT) colonography in comparison with magnetic resonance (MR). METH…

OBJECTIVE: To retrospectively evaluate the feasibility of computed tomography (CT) in depicting deep-infiltrating endometriosis. MATERIALS: The study population included 54 patients (age: mean, 35.5 years; range, 23-48 years) with histolog…

OBJECTIVE: To present the ultrasound and magnetic resonance imaging findings that may allow for a prospective diagnosis and expectant management of decidualized endometriomas because the rare occurrence of decidualization in the ectopic end…

OBJECTIVE: Decidual changes of endometrial tissue in endometriomas during pregnancy may manifest as mural nodules and mimic malignant transformation. We evaluated magnetic resonance findings of decidualized ovarian endometriomas for the dif…

OBJECTIVE: To evaluate the feasibility of magnetic resonance (MR) imaging at 3 T compared with 1.5 T while focusing on the shading sign of endometrial cysts on T2-weighted images. METHODS: Fifteen ovarian endometrial cysts in 10 patients u…

OBJECTIVE: To evaluate the usefulness of computed tomography (CT) in the localization of parenchymal pulmonary endometriosis and to correlate the CT findings with fiberoptic bronchoscopic and pathologic findings. METHODS: A prospective stu…

The magnetic resonance imaging (MRI) findings in 2 cases of ovarian cancer arising in an endometrioma are presented. In both cases, the cancer was evident as an enhancing mass within a blood-filled adnexal cyst. The MRI findings of an enhan…

Although acute appendicitis is the most common disease of the appendix, the appendix can be involved by a wide range of diseases. Diseases other than acute appendicitis may produce signs and symptoms indistinguishable from those of acute ap…

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 radiologic and pathologic features of three cases of adenomyotic cysts are presented. Two cases were subserosal and one was intramyometrial. All three cases had cystic spaces filled with hyperintense fluid on T1-weighted images, which w…

OBJECTIVE: Our goal was to investigate the usefulness of MRI in predicting the response of endometriomas to hormone therapy. MATERIALS AND METHODS: MRI and laparoscopy at the onset of treatment and follow-up MRI after 6 months of hormone t…
