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.
What type of pain is an Epidural Steroid Injection used for. Epidural steroid injections are commonly used to treat radicular pain (pain radiating down an arm or leg) caused by compressed or irritated spinal nerve roots. Pain radiating down the leg is referred to as sciatica. Herniated discs and spinal stenosis are common causes of spinal nerve compression / irritation.
