a) Axial MRI of the brain showing a DBS electrode. b) MRI with electrodes. Under certain conditions, MRI may be performed despite the presence of implanted DBS electrodes. This enables precise documentation of the position of the electrodes. The images show two stimulating electrodes in the VIM nucleus of the left thalamus and a sagittal view of an electrode in the right thalamus. The true diameter of each electrode is 1.3 mm; the electrodes seem much larger because of the metal-induced MRI artefact.
