DIATHERMY. A medical treatment in which heat energy from shortwaves,
microwaves, or ultrasounds are used as treatment or in surgery.
Diathermy Therapy - Energy from the diathermy device can be transferred to the SCS
system and can cause the lead to overheat, which may cause damage to the device,
heating and damage to the body, severe injury, and even death.
CT SCAN. A type of technology in which x-ray-like images are taken in sections (slices)
and then re-assembled by computer to provide detailed two- and three-dimensional
pictures of inside the body.
Computed Tomography (CT) – Please inform your doctor and medical personnel
conducting your CT scan that you have an implanted SCS system. You must turn your
device off temporarily while the scan is being conducted. It is important that the
person conducting your CT scan does the following:
• Determines the device type;
• If practical, tries to move external devices out of the scan range;
• Minimizes x-ray exposure to the implanted or externally worn electronic
medical device by:
o Using the lowest possible x-ray tube current consistent with obtaining
the required image quality; and
o Making sure that the x-ray beam does not dwell over the device for
more than a few seconds;
Important note: For CT procedures that require scanning over the medical device
continuously for more than a few seconds, as with CT perfusion or interventional
exams, attending staff should be ready to take emergency measures to treat adverse
reactions if they occur.
After CT scanning directly over the implanted or externally worn electronic medical
device:
• You should turn your Senza system device back on.
