brain mapping: functional MRI and DTI. Functional MRI (magnetic resonance imaging) is a noninvasive diagnostic test that measures small changes in blood flow as a person performs tasks while in the MRI scanner. Functional MRI detects the brain in action (e.g., speaking or moving).
Back injections may help treat two major back pain problems: radiculopathy and spinal stenosis. Doctors also use injections for other types of back pain. Sometimes, they also use them to help find out what's causing the pain. Radiculopathy refers to inflammation or damage to a nerve usually in the neck or the low back.
Other Types of Injections. Hyalgan is another type of hyaluronate injection that may be used to treat knee pain; this is similar to Synvisc and is usually given to individuals with osteoarthritis. Euflexxa is an injection also used in treating osteoarthritis and is a derivative of hyaluronate.
