MRI can clearly identify some of the signs of osteoarthritis, including whether cartilage is wearing away. MRI can also detect signs of rheumatoid arthritis, but a doctor will also use a variety of other tests, such as blood tests. Doctors can distinguish between soft tissues and fluids using MRI.
MRI is the most effective way to diagnose problems within any joint and the image sensitivity makes it the most accurate imaging tool available in detecting arthritis and other inflammatory changes.
The bottom line is that not all pain is able to be detected on an x-ray or MRI. That does not mean that there is nothing there that needs to be treated or diagnosed. In fact, it means that it is possibly a precursor to something going really wrong and then eventually needing surgery because it eventually winds up torn.
The radiographic hallmarks of primary osteoarthritis include nonuniform joint space loss, osteophyte formation, cyst formation and subchondral sclerosis.
Diagnosis of Osteoarthritis
Having a physical exam to check your general health, reflexes, and problem joints. Having images taken of your joint using: X-rays, which can show loss of joint space, bone damage, bone remodeling, and bone spurs. Early joint damage does not usually appear on x-rays.
Radiography is widely accepted as the gold standard for diagnosing osteoarthritis (OA), but it has limitations when assessing early stage OA and monitoring progression.
The MRI scan provides clear and detailed images of soft tissue. However, it can't 'visualise' bone very well, since bone tissue doesn't contain much water. That is why bone injury or disease is usually investigated with regular x-ray examinations rather than MRI scanning.
MRI can be used to view arteries and veins. Standard MRI can't see fluid that is moving, such as blood in an artery, and this creates "flow voids" that appear as black holes on the image. Contrast dye (gadolinium) injected into the bloodstream helps the computer "see" the arteries and veins.
However, due to the use of the strong magnet, MRI cannot be performed on patients with: Implanted pacemakers. Intracranial aneurysm clips. Cochlear implants.
PsA is often undiagnosed and can be misdiagnosed for rheumatoid arthritis (RA) or osteoarthritis (OA), especially in a non-rheumatologic setting [7–9]. RA is a chronic inflammatory arthritis typified by pain, swelling, and stiffness of the joints, particularly symmetric small-joint synovitis of the hands and feet [10].
Osteoarthritis is a degenerative disease that worsens over time, often resulting in chronic pain. Joint pain and stiffness can become severe enough to make daily tasks difficult.
Osteoarthritis symptoms range from stiffness and mild pain to persistent, severe joint pain. Common signs include swelling and tenderness, stiffness after getting out of bed, and a crunching feeling or sound of bone rubbing on bone.

No blood test can definitively prove or rule out a diagnosis of rheumatoid arthritis, but several tests can show indications of the condition. Some of the main blood tests used include: erythrocyte sedimentation rate (ESR) – which can help assess levels of inflammation in the body.
Autoimmune demyelinating disorders such as ADEM and NMO may be particularly challenging to distinguish from MS, hampering a prompt and accurate diagnosis [10]. MRI is currently the most valuable tool in diagnosis and differential diagnosis of ADD.
An MRI machine uses powerful magnets that can attract any metal in your body. If this happens, you could get hurt. It can also damage equipment that's implanted in your body -- a pacemaker or cochlear implant, for instance. Also, metal can reduce the quality of the MRI image.
You must lie very still during the scan. If you move, the MRI scan pictures may not be clear. Your primary care physician may order you a mild sedative if you are claustrophobic (afraid of closed spaces), have a hard time staying still, or have chronic pain.
A CT scan is much faster than an MRI. It's super-quick. The preparation usually takes longer than the scan itself, which lasts a minute or less. If someone is in a lot of pain, or if they find it hard to hold still for long periods of time, then a CT scan is often your best option.
Does an MRI scan show nerve damage? A neurological examination can diagnose nerve damage, but an MRI scan can pinpoint it. It's crucial to get tested if symptoms worsen to avoid any permanent nerve damage.
MRIs create images using a radiofrequency magnetic field, a technique that clearly shows pinched nerves, disc disease, and inflammation or infections in the spinal tissues. MRI is usually the preferred imaging for pinched nerves.
Benefits of an MRI for Back Pain
An MRI scan can reveal a range of painful spine and back conditions, including: Degenerative diseases: Chronic conditions, including multiple sclerosis, can be diagnosed with an MRI.
Symptoms of osteoarthritis may arise before the damage can be seen in standard X-rays. For this reason, radiologists at Hospital for Special Surgery often use the more sensitive MRI, CT and ultrasound forms of imaging, which are superior for detecting early osteoarthritis.
The radiographic hallmark of osteoarthritis is asymmetric loss of cartilage space. Osteophytosis bony eburnation, subchondral cysts, and eventual subluxation follow. Osteoporosis and erosions are not usual features of this disease.
The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function.
