• Check that the Senza system is working properly.
• Contact your doctor as soon as possible if you suspect the Senza system is
not functioning properly after a CT scan.
MRI SCAN. A type of technology in which electromagnetic energy is used to take
images of soft tissue in the body.
Magnetic Resonance Imaging (MRI) - The Senza system is MR Conditional which
means that safety has been demonstrated only within specifically defined conditions.
Scanning under different conditions may result in severe injury, death or device
malfunction. If your doctor determines it is safe for you to have an MRI, your doctor
will have you turn off the device before the scan and turn it back on when the scan is
complete. This should be done with extreme caution, since these scans may injure you
or damage the device. Never undergo an MRI scan without making sure the team
doing the scan knows you have an SCS device.
If your doctor recommends an MRI, inform the doctor that you have the Senza Spinal
Cord Stimulation system and show him/her your patient ID card (refer to Your Patient
ID section in this manual). The doctor will need to take specific precautions (as
identified in the 1.5T and 3T MRI Guidelines) to prevent patient injury and device
damage. Do not take the trial stimulator, patient remote, or charger into the MRI scan
room. They are not considered safe for MRI and may be rapidly pulled into the MRI
scanner. In doing so, they may strike and injure a person.
Before undergoing these or any other procedures, discuss them with your doctor to
be sure they are safe for you.
LITHOTRIPSY. The use of sound waves to help break up calcified stones in the body.
EXTERNAL DEFIBRILLATION. The emergency use of two large paddles placed on the
chest to deliver a large amount of electrical energy to “re-start” the heart.
ULTRASOUND PROCEDURES. Any number of procedures that use sound waves to get
images of the soft tissue in the body.
RADIATION. The use of radiation energy for therapy. There are many types of
radiation treatments. Radiation can be as simple as an x-ray of the body or it can be
targeted therapy to kill cancer cells (radio therapy).
