The Use of Surface Coils for Magnetic Resonance‐guided lnterventional Procedures

The advantages of surface coils for magnetic resonance imaging (MRI) of superficial structures include improvement in signal and decreased noise. There is now a growing use ofMRI to guide interventional procedures [1–4]. Because of the geometry of needles and other interventional devices, which extend outside the patient, optimal head receiver coils often cannot be used for imaging and the lower signal‐to‐noise body coil must be used because of its large size.
