摘要

We report an unusual case of magnetic resonance imaging (MRI) induced thermal injury. A 45-year-old man without systemic disease came for MRI study due to a left thigh tumor. During the MRI examination, the patient mentioned a prickling sensation in his lower legs, but this did not draw any attention from the staff. After the exam, a pair of symmetrical burn wounds were found at the medial sides of his bilateral calves. They were usually caused by an unexpected electrical loop formation inside the body. This is the first case of MR thermal burn injury in the 20-year operation history of our MR scanner. We report this case to remind the potential causes of MRI thermal injury, and what should we do to avoid the unnecessary thermal injury to patients.
