  • capillary
  • Cerebral microvascular disease in diabetes has been attributed to the effects of chronic hyperglycemia on capillary structure ( 2 ), endothelial reactivity ( 3 ), and blood-brain barrier permeability, thus affecting regional metabolism and blood flow regulation ( 4 ). (diabetesjournals.org)
  • PSV represents a unique event in arterial blood flow, and, possibly, capillary blood flow fluctuations may not be related directly to very brief moments during the cardiac cycle. (bmj.com)
  • it relies on tracking the non-uniform distribution of red blood cells within the capillary and is capable of dealing with very low signal-to-noise ratios. (arvojournals.org)
  • inflow
  • One aneurysm rupturing 5 days after treatment showed also no change in flow pattern, and no change in the maximal inflow velocity. (epfl.ch)
  • Thrombosis
  • To evaluate the haemodynamic changes induced by flow diversion treatment in cerebral aneurysms, resulting in thrombosis or persisting aneurysm patency over time. (epfl.ch)
  • Relative flow velocity and WSS reduction in and of itself may result in aneurysm thrombosis in the majority of cases. (epfl.ch)
  • patterns
  • Pre- and post-treatment haemodynamics were compared, including mean and maximal velocities, wall-shear stress (WSS) and intra-aneurysmal flow patterns. (epfl.ch)
  • Changes in flow patterns were recorded in only one case. (epfl.ch)
  • One aneurysm remaining patent after 1 year showed no change in flow patterns. (epfl.ch)
  • patients
  • G6PD deficiency, absence of alpha-thalassemia, and hemolytic rate at baseline are significant independent risk factors for abnormally high cerebral velocities in patients with sickle cell anemia," Blood , vol. 112, no. 10, pp. 4314-4317, 2008. (hindawi.com)
  • Eight patients with aneurysms at the para-ophthalmic segment of the internal carotid artery were treated by flow diversion only. (epfl.ch)
  • The purpose of this study was to investigate the effects of whole-body vibration (WBV) on blood flow velocity and muscular activity after different vibration protocols in Friedreich"s ataxia (FA) patients. (galileo-training.com)
  • WBV is an effective method to increase blood flow and to activate muscle mass in patients with Friedreich"s ataxia, and could therefore be considered to be incorporated in rehabilitation programs of this collective. (galileo-training.com)
  • To examine the retrobulbar blood flow parameters and structural and functional progression in patients with open-angle glaucoma (OAG) over a 4-year period. (arvojournals.org)
  • In this cohort of patients with OAG, lower OA blood flow values at baseline were predictive of glaucomatous structural and functional progression after 4 years. (arvojournals.org)
  • aortic
  • Measurements of left and right ventricular stroke corresponded closely with those of aortic (r=0.98) and pulmonary flow (r=0.99) respectively, and Qp : Qs flow ratios agreed with stroke volume ratios (r=0.92). (springer.com)
  • estimation
  • This includes synthetic aperture imaging using either spherical or plane waves with velocity estimation performed with directional beamforming or speckle tracking. (dtu.dk)
  • A method for extending the 2D TO method to 3D vector velocity estimation is presented and the implications for future vector velocity imagi- g is indicated. (dtu.dk)
  • cardiovascular
  • Analysis of the blood flow velocity in the forearm was made in comparison to established methods of estimating endothelial function, clinical markers of cardiovascular risk, the Framingham risk score and global atherosclerosis determined by whole body magnetic resonance angiography. (diva-portal.org)
  • clinical
  • Several clinical examples of complex flow in e.g. bifurcations and around valves have been acquired using a commercial implementation of the method (BK Medical ProFocus Ultraview scanner). (dtu.dk)
  • Magnetic resonance velocity mapping: Clinical application of a new technique. (springer.com)
