What Is A Susceptibility Artifact On A Mri. These artifacts can be either helpful or. 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.

Web the susceptibility artifacts are often subtle on clinical images and if not carefully examined they may lead to misdiagnosis. Web magnetic susceptibility corresponds to the internal magnetization of a tissue resulting from the interactions with an external magnetic field. Any ferromagnetic metal strongly disturbs the main magnetic field and introduces inhomogeneity. 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. These artifacts can be either helpful or. If the cardiac stent is outside the region of. Materials that disperse the main field are called diamagnetic. Swi uses a fully flow compensated, long echo, gradient recalled echo (gre) pulse. These artifacts may cause difficulty in interpretation or. Web a susceptibility artifact is expected also in low magnetic fields, but less.
Materials that disperse the main field are called diamagnetic. Materials that concentrate the field are called paramagnetic ,. When two tissues with different magnetic susceptibilities are juxtaposed, it causes local distortions in the magnetic field. 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.
