Abstract
Metallic cranial bone flap fixation clamps were tested for compatibility at 1.5-T magnetic resonance (MR) imaging with standardized techniques. There was no magnetic field attraction, heating was minor, and artifacts involved a relatively small signal void. These data indicate that bone flap fixation clamps will not present risks to patients undergoing MR imaging procedures with MR systems of 1.5 T or less.
