title: MR imaging-related electrical thermal injury complicated by acute carpal tunnel and compartment syndrome: case report.
abstract: Magnetic resonance (MR) imaging is generally considered a safe procedure. Contraindications include the presence of foreign objects in or on the body, which may be subject to electromagnetic fields associated with the MR system. Most of these objects are well known and are routinely screened for prior to the procedure. The authors report an unusual adverse event that appears to have been caused by a unique combination of factors involving an identification bracelet, an item not previously known to present any risks. To the authors' knowledge, this is the first report in the literature of a severe electrical thermal burn that required surgical intervention. Identification bracelets may need to be removed or padded to prevent direct contact with the patient's skin during all MR imaging examinations for patients unable to communicate, such as those requiring sedation or general anesthesia.
