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.
Epidural Steroid Injections (ESIs) are a common method of treating inflammation associated with low back related leg pain, or neck related arm pain. In both of these conditions, the spinal nerves become inflamed due to narrowing of the passages where the nerves travel as they pass down or out of the spine.pidural Steroid Injections (ESIs) are a common method of treating inflammation associated with low back related leg pain, or neck related arm pain.
