Ultrasonographically diagnosed dermoid cysts do not influence ovarian stimulation response in an fertilization cycle.

To determine if patients with a DC respond similarly to ovarian stimulation when compared to patients without a DC. Infertility patients with a DC that underwent IVF between January 2009 and December 2016 were included. A cystic mass with mixed echogenicity, internal echoes similar to thick bands, fatty-fluid level, or an echogenic tubercle with acoustic shadow (Rokitansky nodule) within two years of the cycle characterized the diagnosis.

Reproducibility of the International Endometrial Analysis Group Color Score for Assigning the Amount of Flow Within the Endometrium Using Stored 3-Dimensional Volumes.

Objectives: To estimate intraobserver and interobserver reproducibility for assigning an International Endometrial Tumor Analysis (IETA) group color score for endometrial vascularization on color Doppler imaging.

Methods: Sixty-eight endometrial 3-dimensional volumes from endometrial color Doppler assessments of women with different endometrial disorders were evaluated by 8 different examiners (4 skilled examiners and 4 obstetric and gynecologic trainees). One skilled examiner who did not participate in the assessments selected the 68 volumes from a database to select a balanced number of each IETA score.

A Simple Method for Excluding Uterine Canalization Defects Using Two-Dimensional Ultrasound in Infertile Women.

Objective: To compare the uterine transverse diameter (UTD) in women with normal uteri and women with uterine canalization defects as well as to assess its performance for ruling out such defects.

Study Design: Retrospective analysis of prospectively collected data in a series of selected women with primary or secondary infertility. Measurement of UTD and 3D volume acquisition for subsequent off-line analysis was performed in order to identify possible canalization defects.

Malignancy risk of sonographically benign appearing purely solid adnexal masses in asymptomatic postmenopausal women.

Objective: To assess the natural history of benign appearing purely solid ovarian lesions in asymptomatic postmenopausal women.

Methods: Retrospective observational cohort study comprising 99 women (mean age, 58.2 years, ranging from 50 to 77 years) diagnosed as having a purely solid ovarian lesion at transvaginal ultrasound between April 2001 and October 2015.

Training Performance in Diagnosis of Congenital Uterine Anomalies With 3-Dimensional Sonography: A Learning Curve Cumulative Summation Analysis.

Objectives: We evaluated learning curve cumulative summation (CUSUM) of 3-dimensional (3D) sonography for diagnosis of congenital uterine anomalies and the deviations of the level of trainees' performance at the control-stage CUSUM.

Methods: First-year (R1), second-year (R2), and third-year (R3) residents in obstetrics and gynecology received a training program to learn how to analyze 3D sonographic volumes and to classify congenital uterine anomalies. Each trainee worked on 155 3D sonographic volumes from preselected patients.

Diagnosis and laparoscopic management of a rudimentary horn pregnancy: Role of three-dimensional ultrasound.

Rudimentary horn pregnancy occurs in 1 in 76,000-150,000 pregnancies and causes uterine rupture in about 80% of cases. The use of three-dimensional transvaginal ultrasound seems to be useful for its early detection. We present a case of an 8-week pregnancy in a rudimentary horn, managed by laparoscopic excision.

Three-dimensional sonography for diagnosis of rectovaginal septum endometriosis: interobserver agreement.

Objectives: The aim of this study was to evaluate the interobserver agreement for diagnosis of deep endometriosis of the rectovaginal septum using introital 3-dimensional (3D) sonography.

Methods: Two experienced observers (observers A and B) performed a retrospective review of stored 3D sonographic volumes from a sample of 84 consecutive patients with a clinical suspicion of endometriosis. Each observer, independently and blinded to each other, evaluated the presence or absence of involvement of the rectovaginal septum.

Normal and abnormal images of intrauterine devices: Role of three-dimensional sonography.

The purpose of this pictorial essay is to describe the diagnostic value of two-dimensional ultrasound (2DUS) and the additional information that three-dimensional ultrasound (3DUS) provides in the assessment of location, type and complications of IUDs.

Clinical and sonographic features of uncommon primary ovarian malignancies.

Purpose: To describe the gray-scale and color Doppler ultrasound features of uncommon (<5% prevalence) primary malignant ovarian tumors.

Methods: Retrospective analysis of 98 masses in 89 patients (median age: 50.4 years old, ranging from 15 to 81 years) diagnosed as having an uncommon primary ovarian malignancy.

Intra- and interobserver variability of 2D and 3D transvaginal sonography in the diagnosis of benign versus malignant adnexal masses.

Purpose: The purpose of this study was to investigate the intraobserver and interobserver agreements in the diagnosis of malignant versus benign adnexal masses using two-dimensional ultrasonography (2D US) and three-dimensional ultrasonography (3D US).

Methods: Two experienced sonographers performed a retrospective review of digitally stored 2D images and 3D data from a sample of 41 consecutive patients with a diagnosis of adnexal mass. Each observer independently, and blinded to each other, evaluated the 2D static images of each adnexal mass and then the 3D volumes 1 week later.

The diagnosis of ovarian cancer: is color Doppler imaging reproducible and accurate in examiners with different degrees of experience?

Objective: To evaluate the reproducibility and accuracy of color Doppler flow location in indeterminate masses after a gray-scale sonography in the diagnosis of ovarian malignancy.

Methods: Digitally stored color Doppler sonographic images from a random sample of 130 women with an indeterminate adnexal mass submitted to surgery were evaluated by six different examiners with different degrees of experience. A mass was graded malignant if flow was shown within the excrescences or solid areas.

Diagnosis of endometriosis of the rectovaginal septum using introital three-dimensional ultrasonography.

Objective: To evaluate the diagnostic accuracy of introital three-dimensional (3D) transvaginal sonography for preoperative detection of rectovaginal septal endometriosis.

Design: Ultrasonographic results were compared with surgical and histologic findings.

Setting: University Department of Obstetrics and Gynecology.

Assessment of ovarian vascularization in the polycystic ovary by three-dimensional power Doppler ultrasonography.

Objective: To assess whether there are differences in ovarian echogenicity and vascularization as assessed by three-dimensional power Doppler angiography (3D-PDA) between women with polycystic ovaries (PCO) and women with normal ovaries (NO).

Methods: Eighty-three women were classified into two groups according to the 2003 Rotterdam consensus criteria. The NO group comprised women (n = 45) with regular menstrual cycles and proven fertility, whereas the PCO group comprised women (n = 38) with oligo-anovulation, clinical and/or biochemical features of hyperandrogenism, and polycystic ovary morphology at two-dimensional ultrasound.

Three-dimensional power Doppler ultrasound diagnosis and conservative treatment of ectopic pregnancy in a cesarean section scar.

Objective: To describe three-dimensional ultrasonographic features of an ectopic pregnancy in a cesarean scar.

Design: Description of a case.

Setting: Case report of one patient.

The influence of the depth of embryo replacement into the uterine cavity on implantation rates after IVF: a controlled, ultrasound-guided study.

Background: Traditionally, embryo transfer after IVF has been performed blindly and placing the embryos approximately 1 cm below the fundal endometrial surface. However, it has been suggested that transferring embryos rather lower in the uterine cavity or high in the uterus may improve implantation rates. Nevertheless, there has not yet been a controlled trial to prove this theory.
