Evan Somers, Abstract Co-Author: Nothing to Disclose

1. To discuss with illustrations the indications, techniques, imaging appearance, and complications with commonly used stimulators. 2. To discuss the MR safety and guidelines for these devices.  

Neuromodulation is the electrical or physical modulation of a nerve to influence the physiologic behavior of an organ. In this exhibit we present with illustrations the indications, techniques, imaging appearance, and the complications of commonly used stimulators: 1. Deep brain stimulators: for treatment-refractory movement disorders such as Parkinson’s disease, essential tremor, and dystonias. DBS applications are being explored for depression, Alzheimer’s disease, and addictions. 2. Spinal cord stimulation: for failed back surgery syndrome, refractory angina, peripheral vascular disease, phantom limb pain, spinal lumbar stenosis, postthoracotomy pain syndrome, chronic head and neck pain, and chronic visceral abdominal pain. 3. Vagus nerve stimulation: is a well-established treatment of medically refractory epilepsy. 4. Sacral neuromodulation: Lower urinary tract dysfunction (overactive bladder and nonobstructive urinary retention). 5. We also discuss the various complications associated with neuromodulations. 6.Finally we discuss the MRI compatibility of these devices.
