Ultrasound in Obstetrics & Gynecology

OBJECTIVES: To determine the intraobserver reproducibility of volume acquisition and repeatability of endometrial volume measurements using the VOCAL-imaging program (Virtual Organ Computer-aided AnaLysis). METHODS: Ten three-dimensional (…

In prenatal diagnosis the following alternative dysmorphic syndromes must be considered: Turner, Noonan, microcephalylymphedema and jugular lymphatic obstruction.Turner syndrome was easily excluded by karyotyping.Noonan was unlikely because…

OBJECTIVES: The aim of the study was to investigate whether endometrial thickness, endometrial pattern, endometrial movement and serum estradiol and progesterone affect the outcome of in vitro fertilization. METHODS: Prospectively collecte…

OBJECTIVES: The evaluation of the predictive value of transvaginal ultrasound in the assessment of benign adnexal pathology in premenopausal women, based on the recognition of characteristic morphologic patterns particular to endometriotic …

OBJECTIVE: The endometrium in women on tamoxifen is often made irregular by small cysts. The aim of this study was to assess the accuracy and precision of the measurement of endometrial depth by transvaginal sonography. METHODS: The endome…

This report describes the use of an Argyle trocar catheter for the drainage of pelvic abscesses following transvaginal ultrasound-directed follicle aspiration (UDFA) for oocyte collection. Three patients treated with this technique recovere…

OBJECTIVE: This study aimed to investigate the histology of the subendometrial halo, the junctional zone between the endometrium and myometrium. METHODS: Thirteen ex vivo uteri removed for treatment of menorrhagia were studied. In each cas…

OBJECTIVE: To determine the extent to which Doppler ultrasound examination contributes to a correct specific diagnosis of a pelvic mass when the preliminary diagnosis is based on subjective evaluation of the gray-scale ultrasound image (pat…

OBJECTIVES: The aim of the present study was to examine the role of hysterosalpingocontrast sonography (HyCoSy) as a screening test for endometrial and tubal pathology at the start of the infertility investigation protocol. METHODS: HyCoSy…

OBJECTIVES: To assess the effect of short-term (2-3 weeks) pituitary suppression and controlled ovarian stimulation on ovarian and uterine artery Doppler measurements during the in vitro fertilization (IVF) treatment cycle and to compare th…

OBJECTIVES: To assess the feasibility of imaging low-velocity blood flow in adnexal masses by transvaginal three-dimensional power Doppler sonography, to analyze three-dimensional power Doppler sonography data sets with a new computer-assis…

OBJECTIVE: The aim of this study was to evaluate the role of transvaginal salpingosonography in the assessment of tubal patency among women previously treated conservatively for pelvic inflammatory disease and surgically for a benign ovaria…

BACKGROUND: Nitric oxide is a potent vasodilator and is involved in several physiological events during the female reproductive cycle. OBJECTIVE: The aim of this study was to determine the acute effects of a nitric oxide donor on ultrasoun…

The objective of this study was to measure endometrial thickness by transvaginal ultrasonography during two regimens of hormonal replacement therapy (HRT) in postmenopausal women and to compare these data with endometrial histology. Transva…

The aim of this prospective study was to investigate the relationship between the ultrasonographic appearance of the endometrium, histological dating by biopsy, hormonal profile and impedance within the segmental uterine and ovarian circula…

The differential diagnosis for lower abdominal and pelvic pain following Cesarean section includes many causes, such as endometritis, abscess, pelvic hematoma, wound complications, pelvic vein thrombophlebitis, gastrointestinal dysfunction …

We present a case of a female patient with right lower quadrant abdominal pain, in whom transvaginal ultrasound facilitated the diagnosis of acute appendicitis. The insertion of the appendix into the cecum was demonstrated with direct conti…

The objective of this study was to identify whether the endometrial thickness, or the anteroposterior diameter of the uterus as assessed by transvaginal ultrasonography (TVS), could be used to predict the clinical outcome following transcer…

In the past, most cases of osseous metaplasia of the endometrium were diagnosed following removal of bone from the endometrium by dilatation and curettage and frequently subsequently treated by hysterectomy. Nowadays, management involves a …

A total of 96 women undergoing in vitro fertilization (IVF) treatment were studied on the day of human chorionic gonadotropin (hCG) administration by transvaginal ultrasonography with color and pulsed Doppler ultrasound. We assessed endomet…

The aim of this study was to characterize the appearance of the vascular pattern of endometriomas in terms of color Doppler and to verify the role of Doppler flow indices in differentiating endometriomas from other pelvic masses. Twenty pat…

The aim of this study was to elicit reference data representative of normal findings at transvaginal gray-scale and Doppler ultrasound examination of the uterus and ovaries in postmenopausal women. A total of 144 asymptomatic postmenopausal…

Eleven healthy women with regular menstrual cycles were examined with a combination of two-dimensional real-time ultrasound and color and spectral Doppler techniques on the 7th day after follicular rupture, and on the 1st, 2nd, 3rd and 4th …

The laser has gained increasing importance during recent years as a useful addition to the physician's therapeutic armoury. Reports on successful prostatectomy by ultrasound-guided laser coagulation in an animal model encouraged us to evalu…
