Previous work showed that total variation superiorization (TVS) improves reconstructed image quality in proton computed tomography (pCT). The structure of the TVS algorithm has evolved since then and this work investigated if this new algorithmic structure provides additional benefits to pCT image quality. Structural and parametric changes introduced to the original TVS algorithm included: (1) ...

To determine the diagnostic accuracy of pelvic magnetic resonance imaging (MRI), transvaginal sonography (TVS), and transrectal sonography (TRS) in diagnosis of deep infiltrating endometriosis (DIE).This diagnostic accuracy study was conducted during a 2-year period including a total number of 317 patients with signs and symptoms of endometriosis. All the patients were evaluated by pelvic MRI, ...

OBJECTIVE To compare transvaginal sonography (TVS), sonohysterography (SHG), hysteroscopy and endometrial aspiration (EA) and p53 expression in assessing endometrial abnormalities in women on tamoxifen. METHODS In a cross sectional study of 50 pre- and post-menopausal women receiving tamoxifen for > 2 years, all participants underwent TVS and EA. Those with endometrial thickness > 4 mm on TVS...

Objective: to compare diagnostic values of two dimensional trans-vaginal sonography (TVS) and office hysteroscopy (OH) for evaluation of endometrial pathologies in cases with repeated implantation failure (RIF) or recurrent pregnancy loss (RPL). Methods and Materials: This prospective study was performed in Royan institute from December 2013 to January 2015. TVS was performed before hysteroscop...

OBJECTIVES The aims of this study were to describe and assess the feasibility of measuring cervical length by standard transvaginal sonography (TVS) and transperineal sonography (TPS) in women with a cervical pessary and compare these measurements with those obtained with a new transvaginal technique. METHODS Measurement of cervical length by TPS was attempted immediately before measurement u...

BACKGROUND Transvaginal sonography (TVS) is one of the diagnostic modalities used to evaluate endometrial pathologies in women with abnormal uterine bleeding. It permits use of high frequency ultrasound waves at greater proximity to the uterus. This study aimed at determining the diagnostic accuracy of TVS in identifying endometrial hyperplasia by comparing with histologic findings in perimenop...

The recycling of Waste Electrical and Electronic Equipment (WEEE) is important due to its content of valuable and hazardous compounds. This study investigates the case of the recent technology change within television sets (TVs) and monitors, its impact on the generation of WEEE, and the implications for the recycling industry. In particular, material flow analysis for the time series of 1996-2...

Every TVS-cone metric space is topologically isomorphic to a topological metric space. In this paper, by using a nonlinear scalarization, we give some fixed point results with nonlinear contractive conditions on TVS-cone metric spaces.

adenomyosis is an idiopathic and benign disease in which ectopic endometrial glands embedded deeply in myometrial smooth muscle with the compensatory hypertrophy of the myometrium surrounding the ectopic endometrium (1, 2). there is a correlation between depth of the infiltration and initial too high stage of adenomyosis. lesions may characterize as a diffuse or focal lesions. the highest preva...

results totally, 101women were evaluated during the study. endometriosis was present at laparoscopy in 58 patients. mean age and the duration of infertility were calculated 30.78 ± 4.79 and 4.2 ± 2.91 years respectively. frequencies of each sonographic finding were as follow: echogenic points (%31.68), ovarian endometrioma (%30.69), blurred ovary margin (%7.92), fixation of ovaries (%15.9), dev...
