the carotid is a small mass of chemoreceptor's and sustentacular cells that detects changes in the composition of the arterial blood. the aim of the present study was to identify the size, color, location, blood and nerve supply of the carotid body in makouei sheep. fourteen heads of sheep from both sexes were collected from urmia public slaughter-house. the exact situation and nerve supply of ...

BACKGROUND Fetal color Doppler is important for evaluation of hypoxia in intrauterine growth restriction (IUGR) fetus. OBJECTIVE In this study we compare fetal and maternal color Doppler with blood gas analysis to detect fetal acidosis. MATERIALS AND METHODS In this cross-sectional study we evaluated 100 hospitalized patients with IUGR for comparison of color Doppler results with arterial b...

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 ...

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...

Background: Traumatic pseudoaneurysm of the supratrochlear artery is a rare lesion. It manifests, as a painless mass, in the frontal region following trauma. The unusual incidence and confusing presentation require the clinicians to thoroughly understand its presentation and diagnosis. Diagnosis is typically made on history and physical examination, but it can be confirmed by duplex ultraso...

Dural arteriovenous fistulas (DAVF) are frequent causes of pulsatile tinnitus. Color Doppler sonography may play a useful, complementary role to CTA/MRA and digital subtraction angiography (DSA) in the assessment of these anomalies’ characteristics, such as an ipsilateral increased flow volume and a low resistive index. In this article, we report a case of DAVF first detected with Color Doppler...

Aim: Transcranial​ ​Doppler​ ​(TCD)​ is a widely used method for the evaluation of vertebrobasilar system. There not neither consensus nor significant number publications about normal spectral Doppler waveform and resistance index (RI), peak systolic velocity (PSV), end diastolic (EDV) values basilar artery (BA). We aim to define PSV, EDV, RI BA via TCD in healthy infants. 
 Material Metho...

OBJECTIVE A precise characterization of erectile dysfunction (ED) of vascular origin has not yet been achieved, although cavernous peak systolic velocity (PSV) is generally considered a major parameter. Nevertheless the penile dynamic color Doppler is invasive and linked to several complications. The intima-media thicknesses (IMT) of cavernosal artery would add to the predictive value of vascul...

treatment of stenoses by percutaneous intervention has been shown to increase the longevity of the dialysis shunts (1, 2). In current clinical practice, detection and grading of the stenosis are usually performed using color doppler sonography and digital subtraction angiography (DSA) (3, 4). Color doppler sonography is obviously the first choice of diagnostic method and it can non-invasively d...
