Modern MRI systems employ high-frequency and high-powered radio frequency (RF) pulses. Given this, it is necessary to evaluate the specific absorption rate (SAR) of the irradiated human body. Recently, the materials and shapes of implantable medical devices such as artificial joints or pacemakers have become increasingly diverse. At once, making it more likely that subjects’ implanted medical devices will potentially causing temperature increases in unexpected regions. Therefore, in order to consider the safety of patients with implanted medical devices during MR imaging, it is necessary to comprehend the detailed SAR distribution within the human body. In this study, we evaluated SAR for human body with carotid stent and DBS as one example of medical devices during MR imaging. In these results, SAR value increased around these devices. However, these values were below safety guideline sufficiently. |
