Summary
Axial spondyloarthritis (axSpA) is a chronic inflammatory disease. Medical imaging, particularly MRI, is crucial for early detection and management of axSpA, improving patient outcomes and preventing irreversible damage.
Area of Science:
- Rheumatology and Immunology
- Medical Imaging
- Radiology
Background:
- Axial spondyloarthritis (axSpA) is a chronic inflammatory condition affecting the axial skeleton.
- Historically known as ankylosing spondylitis or HLA-B27 positive spondyloarthropathy.
- Recent advances highlight disease heterogeneity and the importance of early diagnosis.
Purpose of the Study:
- To review the clinical context of axSpA.
- To emphasize the current role of medical imaging in diagnosing and managing axSpA.
- To align radiology reporting with Assessment of SpondyloArthritis International Society (ASAS) definitions.
Main Methods:
- Review of clinical background and imaging modalities for axSpA.
- Focus on magnetic resonance imaging (MRI) for early detection.
- Application of ASAS consensus definitions for standardized reporting.
Main Results:
- MRI is central to identifying early axSpA.
- Standardized reporting improves communication between radiologists and clinicians.
- Early detection is key to slowing disease progression.
Conclusions:
- Medical imaging plays a vital role in the diagnosis and management of axSpA.
- Adherence to ASAS definitions enhances the utility of radiology reports.
- Timely diagnosis and intervention can prevent irreversible structural damage in axSpA patients.

185
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

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...

01:09Overview of the Axial Skeleton
4.8K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

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...
