MRI with DBS for Radiology

MRI with Medtronic Deep Brain Stimulation Systems

This overview of MRI of a patient with an implanted Medtronic deep brain stimulation system includes applicable products and use of the guidelines.

Full-Body MR Conditional Systems

MR Conditional deep brain stimulation systems within the Medtronic Activa® portfolio have received European regulatory approval for full-body magnetic resonance imaging (MRI).* Patients receiving a new system and currently implanted patients may be eligible, under specific conditions of use.* 

Applicable systems: 

  • Activa PC Model 37601 neurostimulator
  • Activa RC Model 37612 neurostimulator
  • Activa SC Model 37603 neurostimulator

 The applicable systems may:  

  • Enable increased power, providing the choice of improved image quality, faster scan acquisition times, or better scan coverage. 
  • Enable full-body scans for diagnosis of co-morbidities.
  • Help improve image quality by minimizing patient movement during an MRI scan.  
  • Allow continued therapy delivery during an MRI scan.

Head-Only MR Conditional Systems 

Other Medtronic DBS systems continue to be approved only for MRI scans of the head, under specific conditions of use.*

Applicable systems:

  • Soletra® Model 7426 neurostimulator
  • Kinetra® Model 7428 neurostimulator
  • Activa SC Model 37602 neurostimulator
  • Model 64001 and Model 64002 pocket adaptors implanted with any DBS system

Contraindication

Certain MRI Procedures -- Use of a full body transmit radiofrequency (RF) coil, a receive-only head coil, or a head transmit coil that extends over the chest area is contraindicated for patients with the following implanted DBS systems or system components: 

  • Soletra Model 7426 neurostimulator
  • Kinetra Model 7428 neurostimulator
  • Activa SC Model 37602 neurostimulator
  • Model 64001 and Model 640002 pocket adaptors implanted with any DBS system

Tissue lesions from component heating, especially at the lead electrodes, resulting in serious and permanent injury including coma, paralysis, or death, can occur if a contraindicated MRI scan is performed on a patient with these DBS systems.


Guidelines and Warnings

Conduct MRI examinations only according to the MRI Guidelines for Medtronic Deep Brain Stimulation Systems. Failure to follow all warnings and guidelines related to MRI can result in serious and permanent injury including coma, paralysis, and death.


About Medtronic DBS Therapy

Medtronic DBS Therapy uses a surgically implanted medical device, similar to a pacemaker, to deliver mild electrical pulses to precisely targeted areas of the brain. The stimulation can be programmed and adjusted non-invasively by a trained clinician to maximize symptom control and minimize side effects.

The therapy is currently approved in Europe for the treatment of the disabling symptoms of essential tremor, Parkinson's disease, chronic intractable primary dystonia, refractory epilepsy, and severe, treatment-resistant obsessive-compulsive disorder.
