Technical considerations and the instrumentation used for pediatric two-dimensional echocardiography and Doppler examination are reviewed. The configurations of sector scanners, the function of the mechanical versus phased array systems and considerations related to lateral, axial and azimuthal resolution requirements are discussed. The performance and requirements for echocardiographic cardiog...

The value of transvaginal B-mode ultrasonography combined with color velocity imaging and pulsed Doppler to detect retained trophoblastic tissue was evaluated prospectively in a series of 40 patients with postpartum (n = 15) or postabortion (n = 25) bleeding. Color velocity imaging was used to identify color-coded blood flow signals within myometrium and/or endometrium. Flow was subjectively qu...

The mechanical properties of the large arteries are important determinants in the circulation physiology. Quantities associated with vessel wall elasticity are of particular interest since they offer a possibility to separate diseased arteries from healthy. Pulse wave velocity (PWV) is a local measure of the arterial wall elasticity. This paper describes a new improved method for non-invasive l...

objective: different surgical procedures have been proposed for the treatment of gingival recessions. the goal of this study was to compare the clinical results of gingival recession treatment using subepithelial connective tissue graft and an acellular dermal matrix allograft. materials and methods: the present study was performed on 5 patients with 9 bilateral miller`s class i or ii gingival ...

Next to dogs and cats, rabbits are popular companion animals in the United Kingdom with 1.7 million kept as pets. Almost 60% of these rabbits are registered with a veterinary practice. The number of reported or anecdotal reports describing congenital or acquired cardiac diseases is increasing, which results in a growing demand to perform echocardiography in pet rabbits as clinical cases. Report...
