MRI as Standard of Care
MRI safety is an important consideration when choosing a deep brain stimulation system for your patients.
Critical Diagnostic Care
MRI scans allow clinicians to detect a wide range of health conditions by viewing highly detailed images of tumors, internal organs, blood vessels, muscles, joints and other areas of the body. MRI scanners use strong magnetic fields and radiofrequency pulses to create images of structures inside the body.
MRI can provide images to help diagnose comorbidities such as tumor, multiple sclerosis, infection, hemorrhage, and spinal injury.1 MRI may be useful in urgent diagnosis, for example ischemic stroke.2
MRI is a valuable tool in healthcare provision, because it:
- Does not use potentially dangerous ionizing radiation associated with imaging options such as X-ray and CT scans.
- Provides enhanced discrimination of soft tissues compared to CT.
- Enables instantly accessible, cross-sectional images to facilitate diagnosis, treatment, guided surgical interventions, and outcomes assessment.
Seven out of ten patients potentially eligible for deep brain stimulation may need an MRI following their implant within 10 years of their implant date.3 Of the seven patients who have an MRI, 71% need an MRI scan of the body, and 29% need an MRI scan of the head.3
Advantages of Full-Body MRI with Activa Systems
Full-body MRI may provide the following advantages:
- Post-implant lead confirmation or case troubleshooting
- Option of an imaged verified deep brain stimulation system implant procedure with direct target visualization4
- Images for diagnosis or monitoring of the progression of Parkinson’s disease or co-morbidities the patient may experience, for example tumor, multiple sclerosis, infection, hemorrhage, and spinal injury1
