Your shared experiences will help: - Lead to more effective treatments and outcomes - Develop programs to meet the needs of you and your community - Shape a powerful agenda that fights for you Now is the time to make your voice count, for yourself and the entire arthritis community. Currently this program is for the adult arthritis community. Since the needs of the juvenile arthritis JA community are unique, we are currently working with experts to develop a customized experience for JA families.

Get Started. As a partner, you will help the Arthritis Foundation provide life-changing resources, science, advocacy and community connections for people with arthritis, the nations leading cause of disability. Join us today and help lead the way as a Champion of Yes. Our Trailblazers are committed partners ready to lead the way, take action and fight for everyday victories.

Our Visionary partners help us plan for a future that includes a cure for arthritis. Our Pioneers are always ready to explore and find new weapons in the fight against arthritis. Our Pacesetters ensure that we can chart the course for a cure for those who live with arthritis. Our Signature partners make their mark by helping us identify new and meaningful resources for people with arthritis. Our Supporting partners are active champions who provide encouragement and assistance to the arthritis community.

Imaging and Nerve Tests for Arthritis Imaging and nerve tests allow a doctor to see the internal structures without doing a medical procedure. X-ray radiography These tests are often used in the diagnosis and monitoring of inflammatory arthritis, degenerative arthritis, fibromyalgia and other pain conditions, back pain and musculoskeletal conditions. Computerized axial tomography CAT or CT scan Combines X-ray equipment with computers to record two-dimensional images of your body and, in some cases, three-dimensional images, showing soft tissues such as ligaments and muscles more clearly than traditional X-rays.

Magnetic resonance imaging MRI Uses a strong magnet linked to a computer to create a detailed image of a cross section of the body providing clear, detailed images of bones and the soft-tissue structures, such as the muscles, cartilage, ligaments, discs, tendons and blood vessels. Bone Scan After injection of a small amount of radioactive dye, a special camera is used to scan the area to detect an increase in blood flow and bone-forming cell activity, which could indicate a tumor, infection or fracture.

Dual energy X-ray absorptiometry DEXA or DXA There are times when more specialized imaging tests may be required — especially when diagnosing osteoporosis or for back or foot problems. Discogram After injection of radioactive dye, the doctor performs a CT scan, which shows tears, scars or changes in the discs in the back.

Video Fluoroscopy Combines the use of an X-ray and a fluorescent screen to show the internal structures and movements of the foot. Arthrography Injection of a contrast dye into the ankle to enable the doctor to better see the joint on X-ray. A false negative diagnosis made off an MRI scan could lead the neurologist and patient down an incorrect path and delay an accurate diagnosis, or potentially miss it entirely.

MRI can detect a variety of conditions of the brain such as cysts, tumors, bleeding, swelling, developmental and structural abnormalities, infections, inflammatory conditions, or problems with the blood vessels. It can determine if a shunt is working and detect damage to the brain caused by an injury or a stroke. Over time, those fibers may undergo degeneration and die, which means the neuropathy is worse because of the loss of more nerve fibers.

This may cause increased numbness, but it usually causes the pain to get better. In this scenario, less pain means greater degeneration. Fracture lines, continuity of marrow signal and the absence of bone marrow oedema as evidenced by signal change on MRI may indicate progression of fracture healing. An MRI scan shows a high level of detail of the soft tissues e. An MRI scan can also tell if the fracture is old or new. Those experiencing ankle pain may be sent for an MRI exam of the ankle.

Healthcare providers use an ankle MRI to diagnose injuries to the bones, tendons, ligaments and cartilage of the ankle. The image will also show tumors, infection and arthritis. Routine ankle MR imaging is performed in the axial, coronal, and sagittal planes parallel to the table top. The foot is imaged in the oblique axial plane ie, parallel to the long axis of the metatarsal bones , oblique coronal plane ie, perpendicular to the long axis of the metatarsals , and oblique sagittal plane , Fig 1.

MRIs are extremely useful at our practice because they allow us to see soft tissue damage and identify underlying issues.
