Blood Flow Simulation in an Aorta with a mild coarctation Using Magnetic Resonance Angiography and Finite Volume Method
Coarctation of the aorta is one of the five main congenital cardiovascular failures, accounting for 6–8 percent of these failures. This research aimed to simulate the blood flow of a seventeen-year-old male teen with a mild coarctation at one-third of his aorta's descending branch. The simulation was performed by extracting the domain and the input pulsatile velocity signal as the boundary cond...
متن کاملComparison of Magnetic Resonance Imaging and Angiography on the Assessment of Coarctation of the Aorta
Background: Coarctation of the aorta (CoA) is encountered in 8% to 10% of all patients with congenital heart defects. In the past, the confirmed diagnosis of CoA relied on angiography, however, this technique uses hazardous radiation, and carries a risk of causing vascular damage at the puncture site, particularly in infants. This study aimed to discover whether magnetic resonance imaging (MRI)...

متن کاملCoronary magnetic resonance angiography.
Coronary magnetic resonance angiography (MRA) is a powerful noninvasive technique with high soft-tissue contrast for the visualization of the coronary anatomy without X-ray exposure. Due to the small dimensions and tortuous nature of the coronary arteries, a high spatial resolution and sufficient volumetric coverage have to be obtained. However, this necessitates scanning times that are typical...
