Ultrasound in Obstetrics & Gynecology

OBJECTIVE: To determine inter- and intraobserver agreement, diagnostic accuracy and the learning curve required for interpreting the 'sliding sign' and predicting pouch of Douglas (POD) obliteration. METHODS: This was an inter-/intraobserv…

To retrospectively evaluate the diagnostic accuracy of power Doppler three-dimensional (3D-PD) ultrasound in discrimination between endometriomas and hemorrhagic cyst. A total of 111 patients with adnexal cystic mass were recruited. Three-d…

OBJECTIVES: To compare the accuracy of transvaginal sonography (TVS) and rectal endoscopic sonography (RES) for the diagnosis of deep infiltrating endometriosis (DIE), with respect to surgical and histological findings. METHODS: This was a…

Adenomyosis is characterized by the presence of ectopic endometrial tissue within the myometrium. Treatment options range from use of non-steroidal anti-inflammatory drugs and hormonal suppression for symptomatic relief, to endometrial abla…

OBJECTIVES: To evaluate the accuracy of various transvaginal sonographic findings in adenomyosis by comparing them with histopathological results and to determine the most valuable sonographic feature in the diagnosis of adenomyosis. METHO…

OBJECTIVES: To assess the value of preoperative ultrasound examination in predicting the feasibility of intermediate-level laparoscopic surgery for benign adnexal masses. METHODS: Symptomatic women with a clinical or ultrasound diagnosis o…

The presence of acoustic streaming in ovarian cysts can be determined by ultrasound imaging and provides an indication of the viscosity of the cyst content. It has previously been demonstrated that the absence of acoustic streaming in endom…

OBJECTIVES: To describe changes in endometrial and subendometrial volume and vascularity during the normal menstrual cycle using three-dimensional (3D) power Doppler ultrasonography. METHODS: Fourteen healthy volunteers, 24-44 years old wi…

UFE is a highly effective, minimally invasive alternative to hysterectomy and is now widely accepted for the management of fibroid-related symptoms. However, there are still some questions regarding the use of UFE as an alternative to myome…

OBJECTIVE: To compare the accuracy of rectal endoscopic ultrasonography (REU) and magnetic resonance imaging (MRI) for predicting rectal wall involvement in patients presenting histologically proven deeply infiltrating endometriosis (DIE). …

OBJECTIVE: To determine the accuracy of transvaginal sonography (TVS) for the diagnosis of deep pelvic endometriosis. METHODS: In a prospective study, 142 women with clinical signs of endometriosis underwent TVS followed by surgical and hi…

OBJECTIVES: Waves of ovarian follicular development during the menstrual cycle have recently been documented in our laboratory. The objective of this study was to test the hypothesis that ultrasonographically detectable changes in the endom…

The discovery of an ovarian mass during pregnancy is often a difficult issue because of the risk related to surgical intervention during pregnancy. Moreover, ultrasound examination is often unable to provide a definitive diagnosis. A case o…

In this issue of the Journal, Yang and Huang1 present a five-patient series exploring the pathophysiology of acute urinary retention in association with a gravid uterus. They report the largest number of cases of urinary retention during pr…

OBJECTIVES: To determine whether acoustic streaming has clinical value in the differentiation between various ovarian and adnexal cysts. METHODS: We assessed 29 adnexal cysts, for which pathological diagnosis was available, for the presenc…

Endometrial tissue has been identified in numerous surgical or procedure-related scars, including Cesarean section scar1, 2, laparoscopic trocar tract2, amniocentesis needle tract3, and perineal episiotomy incision scar4, 5. The incidence o…

The sclerosing stromal tumor (SST) of the ovary is a distinct benign neoplasm that differs from fibromas, thecomas, luteinized tumors and lipoid cell tumors. It accounts for 6% of ovarian stromal tumors and tends to occur at an earlier age.…

I read with great interest the paper of Bazot et al.1 entitled 'Limitations of transvaginal sonography for the diagnosis of adenomyosis, with histopathological correlation'. Certainly, I also think that sonographic diagnosis of adenomyosis …

OBJECTIVE: The aims of this retrospective study were to investigate whether the quantification of ovarian stromal blood flow and/or leptin concentration are predictive of in vitro fertilization (IVF) outcomes in women after laparoscopic ova…

The diagnosis of endometritis is often a challenging task, as signs and symptoms are non-specific and the sonographic findings are variable, including thickening and irregularity of the endometrium and fluid or debris accumulated within the…

OBJECTIVE: To evaluate transvaginal and transabdominal ultrasound scanning, with or without Doppler, as a diagnostic test for the accurate diagnosis of pelvic endometriosis. METHODS: The MEDLINE (1966-2001) and EMBASE (1980-2001) databases…

OBJECTIVE: To analyze the effect of the levonorgestrel-releasing intrauterine system (LNG-IUS) on ovarian cyst formation, endometrial thickness and the size of uterus and uterine fibroids by ultrasonography. SUBJECTS AND METHODS: This was …

OBJECTIVES: To evaluate the accuracy of transabdominal sonography (TAS) and transvaginal sonography (TVS) for the diagnosis of adenomyosis, and to determine the diagnostic relevance of various sonographic criteria. SUBJECTS AND METHODS: A …

OBJECTIVE: To calculate inter- and intraobserver reliabilities for three-dimensional endometrial volume measurements during in vitro fertilization using virtual organ computer-aided analysis (VOCAL). PATIENTS AND METHODS: Three-dimensional…
