HealthWACH: MRI stimulator

Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRIs give different information about the body than can be seen with an ultrasound, X-ray, or computed tomography (CT) scan. An MRI can be done for many reasons. It is used to find problems like tumors, bleeding, injury, blood vessel diseases, or infection.
An MRI can be done for the:
- Head: MRI can look at the brain for tumors, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by stroke.
- Blood vessels: Using MRI to look at blood vessels and the flow of blood through them is called magnetic resonance angiography (MRA). It can find problems in arteries and veins, such as an aneurysm, a blocked blood vessel, or the torn lining of a blood vessel (dissection).
- Chest: MRI of the chest can look at the heart, the valves, and coronary blood vessels. It can show if the heart or lungs are damaged.
- Spine: MRI can check the discs and nerves of the spine for conditions such as spinal stenosis, disc bulges, and spinal tumors.
This condition is a development of nerve damage that causes numbness, pain, and weakness in the hands and feet, but it is not limited to these areas of the body. The pain is usually described as a burning or tingling sensation. Peripheral neuropathy can occur from traumatic injuries, exposure to toxins, infections, and metabolic issues. However, the most common cause of this condition is diabetes. It has been said that symptoms can improve over time and treatment is available for the pain.
This device is the first pain therapy neurostimulator that has been FDA approved for full-body MRI scanning. This treatment allows patients to continue to undergo MRI tests, which were impossible before due to interference with the radio frequency and magnetic fields. This is only recommended for those patients who suffer from chronic pain and who need to continuously undergo MRI tests. If a patient has already had a neurostimulation system implanted, then they must place it to MRI mode prior to the MRI scan and it must be turned off after the scan
