1695 he central focus of carotid Doppler sonography studies is the detection and characterization of atherosclerotic disease and stenosis. Doppler sonography samples are used primarily to quantify velocity elevations at sites of stenosis. However, more subtle clues to disease are contained in the shape and contour of the Doppler sonography waveform itself. Aberrations of waveform morphology can...

Background: Thrombosis of parametrial veins are rarely diagnosed by transvaginal sonography. The clinical importance vein thrombosis is not known. We present the first fully documented case pelvic varicosities with non-occlusive resulting in subsequent development pain that alleviated resolution thrombus. Case report: a perimenopausal woman underwent sonography for routine check-up. patient su...

In this paper, in addition to some elementary facts about the ultra-groups, which their structure based on the properties of the transversal of a subgroup of a group, we focus on the relation between a group and an ultra-group. It is verified that every group is an ultra-group, but the converse is not true generally. We present the conditions under which, for every normal subultra-group of an u...

abstract background: to compare pregnancy outcomes in women at risk for cervical incompetence after elective versus ultrasound- indicated cerclage. methods: in a prospective randomized tlial, singleton pregnancies with at least one previous spontaneous midtrimester loss or early preterm delivery (between 15 and 32 weeks' gestation) who met clinical crite1ia for the diagnosis of cervical in...

This study is to prospectively evaluate the efficiency of sonography for volvulus diagnosis in neonates with clinically suspected intestinal malrotation.A total of 83 patients with suspected intestinal malrotation who underwent detailed abdominal sonography and upper gastrointestinal contrast study were included. Malrotation was characterized by inversion of the superior mesenteric artery (SMA)...

Using the anterior fontanelle as an acoustic window, high resolution gray scale sonography brain scans with mobile apparatus were obtained in 35 premature infants. The sonographic technique provided accurate assessment of ventricular size and detected the subependymal germinal matrix and intraventricular hemorrhages. Ventricular size measurements correlated closely with computed tomography (CT)...

PURPOSE To determine whether color Doppler sonography can be a sensitive alternative to screening arteriography for identifying arterial injury in patients with penetrating traumatic neck injuries. METHODS Fifty-two patients admitted to our trauma center with penetrating neck injuries (gunshot wounds and lacerations) were examined prospectively with color Doppler sonography, and findings were...
