Our goal was to develop an objective computer-assisted volumetric method of assessing vascular flow from colour Doppler ultrasound data of ovarian structures recorded by free-hand movement. We hypothesized that a vascularity index (ratio of the region of blood flood to the region of ovarian structure) obtained from the three-dimensional volumetric ...

Inhere, we compared two of the most common grading systems based on color Doppler ultrasonography (CDU) and physical examination in patients suspected of varicocele. This is a cross-sectional study. Overall, 66 patients clinically suspected of varicocele were visited by an attending urologist and a radiologist for physical examination and CDU. Vari...
Abstract Establishment of pregnancy after embryo transfer is the ultimate goal of an embryo transfer program and increasing pregnancy rates and reducing pregnancy loss are mandatory. The utilization of treatments to improve conception rates in recipient mares has been the focus of several research groups over the last years and the results are cont...
Background/Aims Consistently defining disease activity remains a critical challenge in the follow-up of patients with Crohn’s disease (CD). We investigated the potential applicability of abdominal ultrasonography with color Doppler (USCD) analysis for the detection of morphological alterations and inflammatory activity in CD. Methods Forty-three pa...

ObjectivesTo compare the estimation of carotid artery stenosis by computed tomography angiography (CTA) based on cross-sectional area versus the smallest diameter measurement, and test the accuracy of both CTA measurements using color Doppler ultrasonography (CDUS) as a reference method.MethodsFor 113 carotid arteries with stenosis ≥50% we analysed...
To investigate the carotid atherosclerotic plaque features in patients with acute ischemic stroke. A total of 288 patients meeting the included criteria were enrolled and divided into an ulcerated plaque group (n = 139) and a nonulcerated plaque group (n = 149). Patients in the ulcerated plaque group were further subdivided into

This study assessed the effects of gonadotropin-releasing hormone (GnRH) treatment on Day 5 (Day 0 = estrus) on luteal blood flow and accuracy of pregnancy prediction in recipient cows. On Day 5, 120 lactating Holstein cows were randomly assigned to a control group (n = 63) or GnRH group treated with 100 μg of GnRH agonist (n = 57). On Days 3, 5, 7...
Urology case reports
A 5-month-old boy presented with right scrotal swelling. Color Doppler ultrasonography showed an encapsulated hypoechoic lesion with surrounding hyperemia in the right tail of the epididymis. We performed surgical exploration of the scrotum because it was not considered to be a typical epididymitis. During the operation, we aspirated pus from his r...

PurposeThe gold standard for the diagnosis of malrotation is barium contrast study of the upper gastrointestinal system (UGCS), while color Doppler ultrasonography (CDUS) is another method used in the diagnosis. We investigated the value of CDUS for the diagnosis of malrotation in this study.MethodsUGCS images, CDUS images, plain abdominal images, ...
