Summary
Axial spondyloarthritis (axSpA) imaging uses conventional radiography and MRI to detect inflammatory and structural changes in the sacroiliac joints and spine. This review details imaging benefits, limitations, and future trends for diagnosing axSpA.
Area of Science:
- Rheumatology
- Radiology
- Medical Imaging
Background:
- Axial spondyloarthritis (axSpA) encompasses non-radiographic (nr-axSpA) and classic ankylosing spondylitis.
- Key features include inflammatory and osteoproliferative changes in sacroiliac joints (SIJ) and spine.
- Imaging modalities assess bone marrow edema, erosions, sclerosis, fat metaplasia, ankylosis, spondylitis, spondylodiscitis, facet joint involvement, and syndesmophytes.
Purpose of the Study:
- To provide a comprehensive overview of imaging techniques for axSpA.
- To discuss the benefits and limitations of various imaging modalities.
- To explore the role of imaging in axSpA diagnosis, differential diagnosis, and future trends.
Main Methods:
- Review of current literature on imaging in axSpA.
- Analysis of conventional radiography and magnetic resonance imaging (MRI) findings.
- Discussion of diagnostic criteria for MRI in SIJ and spine.
Main Results:
- Conventional radiography is the gold standard for structural changes.
- MRI is crucial for detecting inflammatory changes.
- Specific MRI criteria exist for SIJ (multiple lesions or single lesion on consecutive slices) and spine (vertebral corner involvement).
Conclusions:
- Imaging plays a vital role in diagnosing and monitoring axSpA.
- Understanding the strengths and weaknesses of each technique is essential for accurate assessment.
- Future trends may enhance the diagnostic capabilities of axial skeleton imaging in axSpA.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
