However, one of the drawbacks of TEE compared to pulmonary artery catheters is the inability to measure real time stroke volume (SV) and cardiac output (CO) continuously. The aim of the present proof of concept study was to validate a novel method of SV estimation, based on pulse wave ...
Determinants of stroke volume response to exercise in patients with mitral stenosis: a Doppler echocar- diographic study. J Am Coll Cardiol. 1993;21:384 -389.Dahan M,Paillole C,Martin D,et al.Determinants of stroke volume response to exercises in patients with mitral stenosis: a Doppler ...
Stroke volume (SV) and cardiac output (CO) are basic hemodynamic parameters which aid in targeting organ perfusion and oxygen delivery in critically ill patients with hemodynamic instability. While there are several methods for obtaining this data, the u
Nature Communications volume 13, Article number: 3683 (2022) Cite this article 8243 Accesses 22 Altmetric Metrics details Abstract The critical brain hypothesis states that biological neuronal networks, because of their structural and functional architecture, work near phase transitions for optimal response...
Most plain CT is acquired as a thin section (1–2 mm) contiguous volume image, however the signal to noise ratio in such images is too low for diagnostic use in stroke with 3–6 mm reconstructions being more commonly used in stroke diagnosis. Many of the more sophisticated image processing...
Infarct volume was evaluated with T2-weighted MRI imaging in the Nuclear Magnetic Resonance Facility at UC Davis. MRI was performed with a 7 T (300 MHz) Bruker Biospec MR system running ParaVision version 5. The RF coil was Bruker’s standard 35 mm ID mouse whole body resonator. Animals we...
Outer plaque contours were corrected to include the adventitial vasa vasorum, which shows hyperenhancement after contrast material administration, while inner vessel wall contours were adjusted to avoid luminal partial volume effects. The adventitial region of the entire vessel wall region was automatically...
Zaharchuk5, E. L. Barbier1,2 & T. Christen5 In this study, we evaluated an MRI fingerprinting approach (MRvF) designed to provide high-resolution parametric maps of the microvascular architecture (i.e., blood volume fraction, vessel diameter) and function (blood oxygenation) ...
implant region exceeded that of surrounding healthy tissue, potentially reflecting that a too dense mixture of cells is being injected or that insufficient dispersion of cells into surrounding damaged tissue occurred (as the whole T2 hyperintense area was used to calculate the volume for injection). ...
The invention provides a system for measuring stroke volume (SV), cardiac output (CO), and cardiac power (CP) from a patient that features: 1) impedance sensor connected to at least
