Brief Summary:

Magnetic resonance imaging (MRI) of patients implanted with deep brain stimulation (DBS) is under strict safety guidelines. Depending on the body part being imaged, the safety may vary.

Many DBS patients will need a spine MRI based on their clinical symptoms. However, the vendor safety guidelines are limiting in terms of possible MR pulse sequences. Based on phantom safety data, we designed a set of MR pulse sequences deemed as safe as possible and the protocol allows acquisition of diagnostic quality MRI images.

Condition or disease Intervention/treatment Phase
Parkinson Disease Dystonia Depression Spinal Stenosis Spinal Diseases Diagnostic Test: MRI of the spine Early Phase 1

Detailed Description:
The patients who clinically require a spine MRI will undergo a spine MRI with our designed protocols to obtain diagnostic quality images. Furthermore, a limited brain MRI will be done before and after to ensure no peri-electrode tissue changes.

Intervention Details:
  • Diagnostic Test: MRI of the spine
    Perform a clinically indicated MRI of the spine in DBS patients

Primary Outcome Measures :
  1. Incidence of MRI-related Adverse Events [Safety] [ Time Frame: Immediately after the MRI ]
    Assess for adverse events as seen on clinical examination

Secondary Outcome Measures :
  1. Assessment of Peri-electrode Tissue Changes (MRI) [ Time Frame: Immediately after the MRI ]
    Assess for peri-electrode tissue changes as seen on MRI
