PURPOSE In the present study, the three-dimensional power Doppler was used as a quantitative method to evaluate its reliability in detecting and assessing of gestational trophoblastic disease (GTD). METHODS 52 GTD patients who received diagnosis and treatment at the first affiliated hospitals of Xi'an Jiaotong University in China between 2011 and 2013 were evaluated using Voluson E8 (GE Medic...

The impact of ultrasonography on the practice of obstetrics has been profound. A carefully performed sonographic examination reveals vital information about fetal anatomy, as well as fetal environment, growth, and well-being. Technology has evolved from producing two-dimensional images of the pregnant uterus to using Doppler methods for measurement of maternal and fetal circulation and to creat...

Background: The aim of this study was to investigate the ability of three-dimensional (3D) ultrasonography and anti-Mullerian hormone (AMH) to predict successful embryo development in patients undergoing in vitro fertilization (IVF) treatment. Materials and Methods: We prospectively studied 28 patients undergoing IVF treatment, using 3D ultrasound Sono automatic volume calculation (AVC) and a 3...

Echocardiography is one of the most important diagnostic tools in veterinary cardiology, and one of the greatest recent developments is real-time three-dimensional imaging. Real-time three-dimensional echocardiography is a new ultrasonography modality that provides comprehensive views of the cardiac valves and congenital heart defects. The main advantages of this technique, particularly real-ti...

background: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...

Angiogenesis is a prominent feature of rheumatoid synovitis. Formation of new blood vessels permits a supply of nutrients and oxygen to the augmented inflammatory cell mass and so contributes to perpetuation of joint disease. Vascular endothelial growth factor (VEGF) is a potent endothelial cell-specific growth factor that is upregulated by proinflammatory cytokines and by hypoxia. Serum VEGF c...

Within the last decade, musculoskeletal ultrasonography is playing an increasingly important role in the evaluation and monitoring of patients with chronic infl ammatory arthritis. High-resolution musculoskeletal ultrasonography allows direct assessment of intra-articular and periarticular infl ammatory activity and structural damage in infl ammatory arthritis. There have been a growing number ...

BACKGROUND Ultrasonography has been extensively used in women suspected of having a gynecological malignancy. The aim of this study is to evaluate the efficacy of 3D ultrasonography and power Doppler for discrimination between benign and malignant endometrium in premenopausal women with abnormal uterine bleeding. METHODS This cross-sectional study included 78 premenopausal women with abnormal...

OBJECTIVE To investigate the value of three-dimensional contrast-enhanced power Doppler ultrasonography (3D-CE-PDU) in the diagnosis of prostate cancer and to compare 3D-CE-PDU with digital rectal examination (DRE), prostate-specific antigen (PSA) levels, grey-scale ultrasonography (GSU) and PDU. PATIENTS AND METHODS The study comprised 30 patients with localized prostate cancer scheduled to ...

results the mean age was 45.6 ± 13.1 (24 to 74 ) years. twenty-two were normal responders [considered as non-organic causes (37.3% of all patients)], 27 were classified as venous leakage, eight had arterial insufficiency and two were mixed type. maximum psv occurred before the fifth minute in 47 patients (92.2%). eight patients completed all phases of erection in the first 5 minutes. we defined...
