Abstract

Magnetic Resonance Imaging (MRI) is the device which is used in medicine for decades to monitorize patients harmlessly. However, patients with metallic implants are under risk during an MRI scan. Medical aimed metallic implants have a potential of interaction with magnetic fields used in Magnetic Resonance Imaging (MRI) device, depending on material type. As a result of the interaction between ferromagnetic / electrically conductive implants and magnetic field, even life of the patient may be under risk. Therefore, MRI safe and unsafe implants must be distinguished before the implantation in order to prevent hazardous circumstances. In this paper, in 3 different shapes, 4 different material contents, MRI safety of 12 individual metallic implants are analysed. Magnetic force/torque formation and RF induced heating of samples are examined in 4 different MRI conditions, which are "Axial and Sagittal T1 Gradient Echo", "Axial and Sagittal T2 Turbo Spin Echo" imaging sequences.
