Blood flow across cerebral aneurysms with magnetic field intervention

An efficient screening method for detecting and assessing aneurysms is magnetic resonance imaging. The current study examines the flow through aneurysmal sacs with six distinct shapes. The study assumes that a strong magnetic field is present in order to create an internal environment for magnetic resonance imaging equipment. The flow properties are investigated, including cell Reynolds number, pressure, and velocity. The study concluded that the globous and bilobar configurations are more susceptible to sac burst and horizontal neck expansion, respectively. The extent of the recirculation zone formed in the globous sac is relatively high. The pressure difference in bilobar, in contrast to other configurations, noticed at the distal node of the aneurysm neck is in the range of 0.089%–0.443%. Magnetic flux density, magnetization vector, magnetic field norm, and Lorentz force magnitude are investigated in the context of magnetic field attributes. The ellipse of transition at the aneurysmal sac's neck is found, along with its dimensions. The size of the ellipse formed denotes the extent of percolation of the magnetic flux into the aneurysms. The most veiled version of the geometry is determined to be multilobar by analyzing the amount of magnetic field line seepage into the sac during magnetic resonance imaging. The weak formulation, the creation of a climate akin to that of the magnetic resonance imaging machine's interior, and the investigation of magnetic field entities during blood flow in the presence of a strong magnetic field are the novel aspects of this work.
