Web susceptibility ( χ) is a measure of the extent a substance becomes magnetized when placed in an external magnetic field. Any ferromagnetic metal strongly disturbs the main magnetic field and introduces inhomogeneity. Web a susceptibility artifact is expected also in low magnetic fields, but less. Swi uses a fully flow compensated, long echo, gradient recalled echo (gre) pulse. Web the most likely source of the artifact is microscopic metal fragments from the burr, suction tip or other surgical instruments, but other possible causes include hemorrhage or paramagnetic suture material. If the cardiac stent is outside the region of. Materials that concentrate the field are called paramagnetic ,. Web magnetic susceptibility corresponds to the internal magnetization of a tissue resulting from the interactions with an external magnetic field. When two tissues with different magnetic susceptibilities are juxtaposed, it causes local distortions in the magnetic field. These artifacts may cause difficulty in interpretation or.
Materials that disperse the main field are called diamagnetic. Materials that disperse the main field are called diamagnetic.

Web susceptibility weighted imaging (swi), originally called bold venographic imaging, is an mri sequence that is exquisitely sensitive to venous blood, hemorrhage and iron storage. If the cardiac stent is outside the region of.
