Fast spin-echo MR of contact points on implanted intracerebral stainless steel multicontact electrodes

AJNR Am J Neuroradiol. 1996 Nov-Dec;17(10):1815-9.

Abstract

A three-dimensional fast spin-echo MR technique is proposed for locating contact points on implanted intracerebral multicontact electrode bundles, Coronal or sagittal reformatting shows the entire trajectory of the electrode bundles. The contract points are clearly visible owing to the absence of coating material associated with a slightly larger susceptibility artifact. Potentially, this technique may preclude postimplantation thin-section CT, with its associated high radiation dose.
