Abstract

Summary: A detachable coil was assessed for magnetic field interactions, heating (body RF coil, SAR of 2.0-W/kg), and artifacts at 3-Tesla. The coil showed no magnetic field interactions and heating was negligible (+0.3°C). Therefore, this coil is safe for a patient undergoing MR imaging at 3T or less. While artifacts may impair the ability to properly visualize anatomy in proximity to this implant, careful selection of imaging parameters can mitigate this problem.

The use of detachable coils is a safe and effective alternative to surgical clipping of intracranial aneurysms (1–3). Accordingly, there has been increased use of these implants (1–3). MR imaging is frequently used to examine patients who have undergone coil embolization by using standard imaging techniques as well as MR angiography (MRA), perfusion-weighted imaging, and diffusi...
