MRI enables direct evaluation of the hyaline cartilage and reflects its biochemical and histological complexity. It is considered to be the best noninvasive method for assessing the joint cartilage because of its high softtissue contrast2, 3, 4, 5.
Computed tomography (CT) has been shown to be more sensitive for detection of erosions in rheumatoid arthritis than MR imaging (,7–,10). However, CT with intravenous contrast material has not been well studied for the detection of synovitis and tenosynovitis in patients with rheumatoid arthritis.
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. MRI is also a key diagnostic tool when patients have lower back pain, radiating pain or hip/groin pain.
A CT scan of the bones may be used to look at your bones for damage, lesions, fractures, or other problems. A CT scan can also look at joints and soft tissues, such as cartilage, muscles, and tendons. It is helpful in staging cancer, too.
There are mainly five kinds of medications commonly used in today's clinical treatment of OA: acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), opioid analgesics, serotonin–norepinephrine reuptake inhibitors (SNRIs), and intra-articular injections.
While X-rays are used to reveal the appearance of osteoarthritic joints to diagnosticians, there is not always a direct correlation between what the X-rays show and the symptoms of osteoarthritis that a patient is experiencing. X-rays of osteoarthritis do not detect early cartilage abnormalities.
In diagnosing arthritis or other joint disorders, an MRI (magnetic resonance imaging) scan can be helpful. An MRI scan is a test that produces very clear pictures of the human body without the use of X-rays. MRI uses a large magnet, radio waves, and a computer to produce these images.
Both types of scan have similar uses, but they produce images in different ways. A CT scan uses X-rays, whereas an MRI scan uses strong magnetic fields and radio waves. CT scans are more common and less expensive, but MRI scans produce more detailed images.
MRI allows to assess the soft tissue and bone marrow involvement in case of inflammation and/or infection. MRI is capable of detecting more inflammatory lesions and erosions than US, X-ray, or CT.
The four stages of osteoarthritis are:
- Stage 1 – Minor. Minor wear-and-tear in the joints. Little to no pain in the affected area.
- Stage 2 – Mild. More noticeable bone spurs.
- Stage 3 – Moderate. Cartilage in the affected area begins to erode.
- Stage 4 – Severe. The patient is in a lot of pain.
MRI can be used to detect brain tumors, traumatic brain injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, and the causes of headache.
MRI is sensitive in diagnosing pathology in groin pain, with injuries to the adductor tendon attachment to the pubic tubercle most commonly identified. Not only can MRI be used to image rectus abdominis/adductor longus aponeurosis and pubic bone pathology, it can also identify hip or inguinal canal abnormalities.
Pros and cons of X-rays for ASInflammation is a common feature of AS, and it can damage joints and connective tissues. X-rays cannot show whether inflammation is present, while MRI scans can.
An MRI of the lumbar spine shows the bones, disks, spinal cord, and the spaces between the vertebral bones where nerves pass through.
The main difference between osteoarthritis and rheumatoid arthritis is the cause behind the joint symptoms. Osteoarthritis is caused by mechanical wear and tear on joints. Rheumatoid arthritis is an autoimmune disease in which the body's own immune system attacks the body's joints. It may begin any time in life.
Pain at the front of the knee can be caused by bursitis, arthritis, or softening of the patella cartilage, as in chrondromalacia patella. Pain on the side of the knee is usually associated with injury to the collateral ligaments, arthritis, or tears to the menisci.
