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.
Cortisone Injection Injectable corticosteroid or âsteroid injectionsâ commonly called âcortisone,â have been used by orthopaedic professionals since the early 1950s for a variety of painful conditions including tendinitis and arthritis. long acting local anaesthetic is either injected prior to injecting the steroid or both the local anaesthetic and steroid are injected mixed together. There is usually immediate pain relief from the injection. The pain returns when the local anaesthetic wears off usually after about 8-14 hours.
