BACKGROUND AND PURPOSE Optimal estimation of cerebral blood-flow volume (BFV) may be an important indicator for better evaluation of the patients with cerebrovascular disorders. In this study, we compared the BFV values at bilateral internal carotid and vertebral arteries of healthy volunteers obtained with color Doppler, power Doppler, and B-flow ultrasound (US) studies and tried to determine ...

Infertility is defined as the failure to conceive a desired pregnancy after 12 months of unprotected intercourse, and affects 10 percent of married couples. The causes of infertility can involve one or both partners. Causes of female infertility: • Fallopian tube factors (damage or blockage due to salpingitis, EP) • Ovulation disorders (PCOS ,Early menopause ) • Uterine factors • Intrauterine l...

Carotid body tumors typically arise at the level of the common carotid bifurcation where the carotid body exists. Superior and inferior extension beyond the carotid body may occur as well, especially if the tumor is long-standing. We herein describe a case of carotid body tumor in a patient who presented with a right-sided neck mass for 30 years. Computed tomography angiography (CTA) and B-mode...

This study evaluated the consistency of manual and automated measurements of monodominant follicle diameter with different follicle size in infertile patients. Transvaginal two-dimensional (2D) ultrasound and SonoAVC (Sonography-based Automated Volume Calculation) were both performed in 226 infertile patients with monodominant follicle growth. 2D diameters were separately compared with SonoAVC-...

OBJECTIVE The goal of this review article is to present the state of the art in the clinical applications and technical performance and interpretation of carotid sonographic examinations. METHODS Relevant publications regarding color and duplex Doppler sonography (CDDS) of the carotid arteries extracted from a computerized database (MEDLINE) and from references cited in these articles not app...

Background: According to Ayurveda, Ambu is one of the four essential factors Garbhasambhav Samugri for formation and development embryo. The word means nutrients growth embryo which it receives from mother. modern science, during implantation, its endometrium. Though some women have normal endometrial thickness, pattern, morphology, still they are unable get impregnated. During peri-implantatio...

Objectives: This prospective study was aimed at evaluation of diagnostic value of Doppler sonography and magnetic resonance (MR) venography in the internal jugular vein territory. Material and methods: There were assessed 126 patients (252 internal jugular veins). The patients were initially diagnosed using Doppler sonography and MR venography, and then catheter venography of the veins was perf...

BACKGROUND GnRH agonist was recently suggested as a novel luteal-phase support that may act at different levels, including the pituitary gonadotrophs, the endometrium and the embryo itself. This prospective randomized study evaluates the effect of GnRH agonist administered in the luteal phase on ICSI outcomes in both GnRH agonist- and GnRH antagonist-treated ovarian stimulation protocols. MET...

BACKGROUND Doppler sonography is a type of sonography used for imaging the blood flow in the vessels and heart. This technique uses ultrasound waves with high frequency. In some patient candidates for venous graft, the identification of the suitable vein is not possible with clinical examination. OBJECTIVE This study compared the effects of preoperative color Doppler sonography of lower extre...

Background In patients with abnormal uterine bleeding, transvaginal ultrasound (TVS) is the first-line diagnostic approach to exclude endometrial pathology. If a thickened endometrium suggests endometrial pathology, sonohysterography, office hysteroscopy or dilatation and curettage are the second-line tests preferred, depending on availability and on the suspected pathology, to exclude malignan...
