Patients with permanent cosmetics and tattoos have potential risk of heating effects during MRI examination. Most of the cutaneous reaction and injury occurred around the tattoos due to the metallic pigments found in the tattoo inks. Previous reports and studies presented that mild edema and redness of the tattoo comprehended as cutaneous burn due to the shape of the tattoo. This study numerically analyzed the RF heating effects around the tattoo with different types and positions. Results show that high SAR and temperature rise were observed around the circular loops, long strips and adjacent point of the tattoo.
