In this report, we describe a continuous murmur heard in a young woman at the beginning of her lactation period, which illustrates a typical example of 'Mammary Souffle', described one century ago. Colour Doppler and pulsed-wave mode echocardiogram allowed to precise, for the first time, the arterial nature of increased systolic and diastolic blood flow in tortuous branches of internal mammary ...

We report the 1D cooling of ^{85}Rb atoms using a velocity-dependent optical force based upon Ramsey matter-wave interferometry. Using stimulated Raman transitions between ground hyperfine states, 12 cycles of the interferometer sequence cool a freely moving atom cloud from 21 to 3 μK. This pulsed analog of continuous-wave Doppler cooling is effective at temperatures down to the recoil limit; w...

We assessed the potential of 2-MHz pulsed-wave transorbital Doppler ultrasonography to delineate the role of the ophthalmic artery as a source of collateral cerebral blood supply by comparing oculopneumoplethysmography, transorbital Doppler ultrasonography, periorbital continuous-wave Doppler ultrasonography, and transcranial Doppler ultrasonography in 25 patients with unilateral internal carot...

The Doppler wave form along the proximal left internal thoracic artery (LITA), which is detected by the parasternal or suplaclavicular view, shows a different pattern from that of the distal side of the LITA due to the effect of blood pulsatility from the subclavian artery. We evaluated postoperative LITA function immediately after surgery with an apical approach of transthoracic pulsed Doppler...

The purpose of this article is to review the literature on essential technical aspects implementing pulsed Doppler, as part teachings their use in diagnosis changes canine reproductive system. A narrative was carried out, using scientific articles, monographs, theses and dissertations published available online databases: Periodical Capes (Coordination for Improvement Higher Education Personnel...

In symptomatic severe aortic regurgitation, left ventricular diastolic pressure increases rapidly, often exceeding left atrial pressure in late diastole. This characteristic hemodynamic change should be reflected in the Doppler mitral inflow velocity, which is the direct result of the diastolic pressure difference between the left ventricle and left atrium. Mitral inflow velocity was obtained b...

Glaucoma is associated with an increased incidence of cardiovascular disease and risk factors. The aim of the study was to assess the left ventricular (LV) function in patients with pseudoexfoliation (PEX) glaucoma using doppler-echocardiographic examinations. Two-dimensional and pulsed Doppler echocardiography of transmitral flow was performed in 21 patients with (PEX) glaucoma and 24 controls...

AbsfructLaboratory measurements of Ku-band scattering at grazing incidence are presented. This study was motivated by the need to understand the processes which significantly contribute to scattering at grazing incidence. A dual polarized (VV, HH) coherent pulsed Ku-band scatterometer with good temporal resolution (3 ns) was used to obtain Doppler spectra and the absolute cross-section of scatt...
