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.
These drugs are given as an intra-articular injection, meaning they are injected directly into the joint space, either as a one-time injection or at weekly intervals depending on the medication. Examples: Synvisc, Synvisc One, Euflexxa, Kenalog, dexamethasone
