Arteriovenous malformation (AVM) is a tangle of various size vessels with arterial and venous histological characteristics but without evidence of an intervening capillary network [1]. Uterine AVM is classified as either congenital or acquired. Definitive diagnosis has been traditionally made by angiography. With the development of color Doppler and power Doppler ultrasound, diagnosis is now ea...

CONTEXT Pancreatic pseudoaneurysm rupture is a rare complication of chronic pancreatitis, with severe prognosis and high mortality. Angiography is usually required for confirmation of the diagnosis, but transabdominal ultrasound and CT angiography are useful noninvasive diagnostic methods. CASE REPORT We present the case of a 66-year-old patient with a large pancreatic pseudoaneurysm of the s...

STUDY DESIGN Cross-sectional observational study. OBJECTIVES To investigate the presence of soft tissue hyperemia in plantar fasciitis with power Doppler ultrasound. BACKGROUND Localized hyperemia is an established feature of tendinopathy, suggesting that neurovascular in-growth may contribute to tendon-associated pain in some patients. The presence of abnormal soft tissue vascularity can b...

BACKGROUND Intratendinous Doppler activity has been interpreted as an equivalent of neovessels in the Achilles tendon and as a sign of tendinosis (AT). AIM To evaluate the vascular response as indicated by color Doppler activity after repeated loading of both symptomatic and non-symptomatic Achilles tendons. MATERIAL AND METHODS Ten non-trained, healthy subjects ran 5 km. Ultrasound (US) Do...

The purpose of this study was to develop an animal model that could be used to test the ability of Doppler ultrasound to detect arterial emboli composed of materials that are often involved in cerebral emboli. Emboli introduced into the rabbit aorta via the left renal artery consisted of clotted whole blood, platelets, atheromatous material, fat, or air. The ultrasound examination was carried o...

      Background: Computed tomography scans (CT scan) and X-rays are used to diagnose paediatric maxillary sinusitis. This study aimed at exploring the diagnostic value of the conventional and colour Doppler ultrasounds and their specific findings in cases of paediatric sinusitis.    Methods: A total of 60 children diagnosed with sinusitis were included in this s...

Background: To evaluate the role of 3D, 4D and color Doppler ultrasound (US) in the assessment of early human development. Materials and Methods: 380 women with uncomplicated early pregnancy between 5 and 14 weeks were evaluated by 3D, 4D and color Doppler US. Results: Regression analysis revealed exponential rise of the gestational sac volume with gestational age throughout the first trimester...

The metabolic rate of oxygen consumption, an important indicator of tissue metabolism, can be expressed as the change of net blood oxygen flux into and out of a tissue region per 100 g of tissue. In this work, we propose a photoacoustic and Doppler ultrasound method for imaging local blood oxygen flux of a single vessel. An imaging system for combined photoacoustic and high-frequency ultrasound...
