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...

Image Reconstruction with Time-Resolved Contrast Enhanced Magnetic Resonance Angiography

Contrast enhanced magnetic resonance angiography enables one to visualize the vascular system of the human body. Typically, using conventional measurement techniques, one three-dimensional volume of the vascular system can be measured during the passage of the contrast agent. More recently, medical doctors desire time-information of the blood-flow, or want to scan time-dependent phenomena. To e...

magnetic resonance angiography in the diagnosis of cerebral arteriovenous malformation and dural arteriovenous fistulas: comparison of time-resolved magnetic resonance angiography and three dimensional time-of-flight magnetic resonance angiography

background traditional digital subtraction angiography (dsa) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (avm) and dural arteriovenous fistulas (davf). objectives the aim of this study was to analyze different less invasive magnetic resonance angiography (mra) images, time-resolved mra (tr-mra) and three-dimensional ti...

Time-resolved Magnetic Resonance Angiography for assessment of recanalization after coil embolization of visceral artery aneurysms

BACKGROUND Follow-up imaging after coil embolization of visceral artery aneurysms is important for detecting recanalization. However, CT examination is susceptible to coil artifacts, which sometimes makes it difficult to assess recanalization. We report 2 cases where recanalization was successfully visualized using time-resolved magnetic resonance angiography after coil embolization of visceral...
