Abstract There is a great need for MRI examinations of patients who have previously undergone deep brain stimulator (DBS) implantation. The current guidelines pertain only to a 1.5‐Tesla horizontal‐bore scanner complying with strict safety regulations. Moreover, almost all published in vitro and in vivo studies concerning patient safety are carried out on 1.5 Tesla MR scanners. The aim of our work is to share our clinical experience of 1.0‐Tesla brain MR imaging. During the past four years, 34 patients with different types of implanted DBS systems underwent 1.0‐Tesla MR examinations to answer diagnostic or clinical questions. Apart from the scanner type applied, all other safety instructions were strictly followed. The MRI itself made no significant difference to the measured impedances or the stimulation parameters required to achieve the optimal therapeutic results. From theoretical considerations, it may be assumed that 1.0‐Tesla MRI can be performed safely on DBS‐implanted patients, provided that all other recommendations are adhered to. J. Magn. Reson.
