MRI-related heating near deep brain stimulation electrodes: more data are needed.
Magnetic resonance imaging (MRI) of patients with implanted deep brain stimulation (DBS) devices poses a challenge for healthcare providers. As a consequence of safety concerns about magnetic field interactions with the device, induced electrical currents and thermal damage due to radiofrequency heating, a number of stringent guidelines have been proposed by the device manufacturer. Very few de...
متن کاملMR imaging-related heating of deep brain stimulation electrodes: in vitro study.
BACKGROUND AND PURPOSE Recent work has shown a potential for excessive heating of deep brain stimulation electrodes during MR imaging. This in vitro study investigates the relationship between electrode heating and the specific absorption rate (SAR) of several MR images. METHODS In vitro testing was performed by using a 1.5-T MR imaging system and a head transmit-receive coil, with bilateral ...
متن کاملHeating induced near deep brain stimulation lead electrodes during magnetic resonance imaging with a 3 T transceive volume head coil.
Heating induced near deep brain stimulation (DBS) lead electrodes during magnetic resonance imaging with a 3 T transceive head coil was measured, modeled, and imaged in three cadaveric porcine heads (mean body weight = 85.47 ± 3.19 kg, mean head weight = 5.78 ± 0.32 kg). The effect of the placement of the extra-cranial portion of the DBS lead on the heating was investigated by looping the extra...
متن کاملO10: Deep Brain Stimulation and Psychiatry
The use of deep brain stimulation in psychiatric disorders has received great interest owing to the small risk of the operation, the reversible nature of the technique, and the possibility of optimizing treatment postoperatively. Currently deep brain stimulation in psychiatry is investigated for obsessive-compulsive disorder, Gilles de la Tourette’s syndrome and major depression. This presentat...
