This study was performed to determine the effectiveness of duplex ultrasound as the primary diagnostic imaging test before endovascular treatment and to estimate the potential cost-savings compared with the use of other technologies.MethodsThe diagnostic evaluations of all patients treated for LEOD by a...

Aims The aim of the study was to evaluate the importance of duplex/colour Doppler ultrasound in a protocol of hepatic regional chemotherapy, by measuring the blood flow in the hepatic artery, portal vein, hepatic veins, and inferior caval vein of patients with unresectable liver metastases from ...
Ultrasound technicians perform most of the peripheral arterial ultrasound examinations. However, any trained medical personnel may perform the examination. Competent practitioners can perform a point-of-care ultrasound and help in triage care.[8] Technique or Treatment Duplex Ultrasonography of the Lower ...
The diagnosis of venous ulcers is clinical, with the underlying venous insufficiency confirmed byDuplex Ultrasound. Most commonly venous incompetence occurs at the sapheno-femoral or sapheno-popliteal junctions, although it may occur in any perforator. ...
The patient was placed in the supine position, and local anesthesia was administered. Ultrasound-guided access of the left common femoral artery (CFA) was obtained. Using an up-and-over technique, a 0.035-inch Storq steerable guidewire (Cordis) was advanced to the right popliteal artery. The ...
the most commonly applied BC is the normal stress, which accounts for the pressure exerted by the blood within the cardiac cavity [33,40,48,65]. For simplicity, the ventricular base is typically fully constrained from longitudinal movement (i.e. shortening or lengthening along the apex-base di...
This study reviews our experience with duplex ultrasound arterial mapping (DUAM) for preoperative evaluation in 466 patients (262 men) who underwent 485 lower extremity revascularization procedures from January 1, 1998 to May 30, 2001. Preoperative imaging consisted of DUAM alone in 449 procedures ...
Fig. 1. Colour Doppler ultrasound recordings. (a) Normal recording at position 3 in the orbit showing the central retinal artery (arrow) and posterior ciliary arteries (arrowheads). (b) Recording from the optic nerve head in a patient with central retinal artery occlusion. Note the complete ...
The enlargement of proximal elastic arteries with aging and elevated MBP has been extensively described in humans in studies using ultrasound, particularly high-resolution echotracking systems [20,21]. Magnetic resonance imaging (MRI), which precisely investigates the geometry of the aorta, show...
