Understanding Ankylosing Spondylitis (AS): Ankylosing spondylitis is a chronic inflammatory disease that mainly affects the spine and sacroiliac joints. It can cause persistent pain and stiffness, impacting quality of life. Throughout May, which is dedicated to raising awareness of this condition, it is important to highlight recent advances in diagnostic methods that allow for more prompt and tailored management.

What is Ankylosing Spondylitis?

Ankylosing spondylitis (AS) is one of a group of inflammatory diseases known as spondyloarthropathies, which primarily target the joints but can also affect organs such as the eyes or heart. It is characterized by chronic inflammation of the sacroiliac joints and spine, which may result in lower back pain, morning stiffness, and— in some cases — the progressive fusion of vertebrae.

Although the exact causes are still being researched, genetic factors—especially the HLA-B27 antigen—and immune mechanisms are believed to play a role in its development. AS is more commonly seen in young adult men, making early detection even more vital for slowing progression and preserving quality of life.

The Value of an Accurate Diagnosis

The diagnosis of AS relies on clinical evaluation, medical imaging, and established criteria. When suggestive symptoms are present, referral to a specialized healthcare professional and prompt imaging may help confirm the diagnosis sooner, enabling appropriate management.

Essential Imaging Exams at Radiméd

Radiméd offers advanced imaging technologies and a team of experienced radiologists to support the diagnosis of ankylosing spondylitis. Here are a few exams that may be prescribed by a physician for this condition:

  • Standard X-rays: X-ray views of the lumbar spine and sacroiliac joints help to look for signs of AS, such as erosions, sclerosis, or features of sacroiliitis. These images support the clinician’s overall assessment.
  • MRI (Magnetic Resonance Imaging): MRI is especially valuable for detecting early inflammation that isn’t visible on traditional X-rays. Our advanced SIGNA™ Artist equipment provides high-resolution images that can reveal signs of inflammation—such as bone marrow edema or active sacroiliitis. MRI can inform therapeutic decision-making for physicians.
  • CT Scan (Computed Tomography): In certain cases, CT scans can be useful for assessing bone structure abnormalities, particularly in the later stages of the disease. This can provide additional information for a thorough assessment.
  • Musculoskeletal Ultrasound: Ultrasound may be used to examine the entheses—the areas where tendons and ligaments attach to bone—where inflammation can occur in AS patients. The LOGIQ™ E10 device allows for precise assessment to guide clinical decision-making.

General Tips for Joint Health

While only a medical team can provide advice tailored to each patient, here are some general guidelines that may help support joint health:

  • Make adapted physical activity—flexibility, endurance, strength training—a regular part of your routine.

  • Aim for a balanced diet rich in calcium, vitamin D, and antioxidants.

  • Avoid tobacco use, as it is associated with worsening of the condition.

  • Maintain a healthy weight.

  • See your healthcare professional regularly for individualized follow-up.
