background: müllerian anomalies are associated with infertility. hysteroscopy as the gold standard for evaluating müllerian anomalies is an invasive, expensive and risky procedure which requires enough experience. transvaginal sonography (tvs) and hysterosalpingography (hsg) are less invasive procedures, but there is little known about the accuracy of these tests. the aim of this study was to e...

We study the problem of variable selection for linear models under the high-dimensional asymptotic setting, where the number of observations n grows at the same rate as the number of predictors p. We consider two-stage variable selection techniques (TVS) in which the first stage uses bridge estimators to obtain an estimate of the regression coefficients, and the second stage simply thresholds t...

OBJECTIVE To compare the diagnostic performance of saline infusion sonohysterography (SIS), transvaginal ultrasound (TVS), and diagnostic hysteroscopy (DH) in the detection of endometrial lesions in symptomatic women. DESIGN Prospective, comparative study. SETTING Obstetrics and Gynecology Department of a tertiary academic hospital. PATIENT(S) A total of 105 consecutive women presenting i...

BACKGROUND To assess the attitude to and perception of transvaginal sonography (TVS) among Nigerian women of mixed educational status in order to ascertain factors that may prevent them from submitting to TVS when recommended. METHODS A Cross-sectional survey was adopted for the study. In all, one missionary, one government and eight private hospitals were enlisted. The instruments for data c...

BACKGROUND Endometriosis and possible rectal involvement are difficult to assess by physical examination. Previous studies have shown the diagnostic value of magnetic resonance imaging and rectal endoscopic sonography (RES) in this setting, but not that of transvaginal sonography (TVS). The aims of this study were to compare the accuracy of TVS and RES for the diagnosis of pelvic endometriosis,...

BACKGROUND Accurate diagnosis of uterine abnormalities has become a core part of the fertility work-up. A variety of modalities can be used for the diagnosis of uterine abnormalities. OBJECTIVES This study was designed to assess the diagnostic accuracy of transvaginal ultrasonography (TVS) in uterine pathologies of infertile patients using hysteroscopy as the gold standard. PATIENTS AND MET...

Recently, there have been several major technical advances in the sonographic diagnosis of ovarian cancer in its early stages. These include improved assessment of tumor morphology with transvaginal sonography (TVS), and detection and characterization of tumor neovascularity with transvaginal color Doppler sonography (TV-CDS) and contrast-enhanced transvaginal sonography (CE-TVS). This paper wi...

Background The performance of TVS, TRS and MRI for the diagnosis of DIE have been separately reported in earlier studies. However, the three methods have not been concurrently compared in terms of their overall performance and classified results as per different anatomical locations of DIE lesions in a large study population. This study was an attempt to compare pelvic magnetic resonance imagin...
