Contraindications to magnetic resonance imaging
radiology.pitt.edufields can induce electrical currents in electri-cally conductive devices and may directly cause neuromuscular stimulation. 3. Pulsed radiofrequency fields—The main biologi-cal effects of radiofrequency fields is their thermogenic effect. Some of the applied energy will be absorbed by the body and converted into heat. The specific absorption ...
Principles of Electrosurgery
www.asit.orgStandard electrical current alternates at a frequency of 60 cycles per second (Hz). Electrosurgical systems could function at this frequency, but because current would be transmitted through body tissue at 60 cycles, excessive neuromuscular stimulation and …
