Absolute contraindications: chest x-ray examinations with abandoned and epicardial leads. Absolute contraindications: chest x-ray examinations with abandoned and epicardial leads. Posteroanterior view of the chest (A) demonstrates an abandoned lead (black arrows) in a patient with a dual-chamber pacemaker device. B, An abandoned right ventricular lead (black arrows) in a patient with a single-lead pacemaker device. The black arrowhead denotes a fracture of the abandoned lead. C, A patient with a biventricular ICD pacing system, which includes transvenous atrial and right ventricular leads and 2 permanent epicardial pacing leads (black arrows). None of these 3 patients would be cleared to undergo MR imaging examination at our institution. A.W. Korutz et al. AJNR Am J Neuroradiol 2017;38:2222-2230 ©2017 by American Society of Neuroradiology
