Investigation of the Boundary Layer Blood Flow and the Initial Factors of Atherosclerosis by the Magnetic Resonance Imaging | Chapter 03 | Emerging Research in Medical Sciences Vol. 2
Aim: study the blood flow and vessel wall viscoelastic alterations at the boundary layer and initial factors of atherosclerosis. Study Design: Magnetic resonance angiography with the follow up flow quantification was carried out voluntary on the healthy persons. Place and Duration of Study: MRI department of the Institute of Clinical Medicine in Tbilisi Rep. Georgia, between September 2012 and July 2017. Methodology: In 12 healthy men (18-52 years of age) at the different sites of the aorta peak velocity, net flow, flow acceleration has been investigated by Magnetic Resonance Angiography. Blood radiodensity (HU) were studied (CT) in different sites of the aorta and vena cava. Results: In the aortic arch in the end systole blood flow separates into the opposite directed streams resulting in the wave superposition. At the outer curvature of the isthmus, flow acceleration in the initial diastole is 6.26 times higher than that in systole. Net flow from systole to di...
