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.
Types of Intra-Articular Injections The aim of intra-articular injections can vary by the drug used. While pain relief is the most common goal, they may also be used to deliver chemotherapy drugs like Doxil (doxorubicin) directly into a joint affected by cancer.
