10). For example, ferromagnetic materials are sub Magnetic susceptibility artifact is seen near structures with very high and low signal intensity (the sinus and brain tissue). Gradient echo sequences are known to demonstrate magnetic susceptibility artifact partly due to the lack of a 180° refocusing pulse. Magnetic Susceptibility Artifact.

During a Magnetic resonance imaging in the vicinity of commercially available venous stents is feasible at 1.5 T with no substantial susceptibility-induced artifacts but reduced transmit and receive B 1 field strengths inside the stents. 2012-09-03 · Diffeomorphic susceptibility artifact correction of diffusion-weighted magnetic resonance images L Ruthotto 1,2,3 , H Kugel 4 , J Olesch 1,5,6 , B Fischer 1,5 , J Modersitzki 1 , M Burger 3 and C H Wolters 2 PROPELLER 3.0 is designed to reduce the effect of patient voluntary and physiologic motion (breathing, flow, peristalsis), and reduce magnetic susceptibility artifacts. It helps generate consistently good, diagnostic quality images even for challenging patients and difficult-to-image anatomies. Magnetic susceptibility artifact has been documented with various implants and devices, which require appropriate identification with screening of patients prior to subjecting them to magnetic resonance examination.
