MRI induced heating for fully implanted, partially implanted and minimally implanted medical electrode leads

One of the critical MRI safety concerns for patients with medical implants is the RF coil induced heating in the vicinity of electrode lead tip. Many works have been carried out to assess such risk for fully implanted leads. However studies on partially implanted, as well as minimally implanted electrodes have not been explored. In addition, effects of statures, weight, ages and many other factors may vary the RF heating dramatically. In this paper fully implanted, partially implanted and minimally implanted medical leads are studied in both adult male and boy models to demonstrate the heating variations due to pathway types and human bodies.
