Insights

This study introduces a reference atlas of wrist MRI images for rheumatoid arthritis. It provides standardized images to improve the accuracy of scoring synovitis, bone edema, and erosions using the OMERACT RA MRI scoring system.

Area of Science:

  • Rheumatology
  • Radiology
  • Medical Imaging

Background:

  • Rheumatoid arthritis (RA) diagnosis and monitoring rely on accurate assessment of joint inflammation and damage.
  • Standardized scoring systems are crucial for consistent evaluation of RA progression using Magnetic Resonance Imaging (MRI).
  • The EULAR-OMERACT rheumatoid arthritis MRI reference image atlas aims to standardize MRI interpretation in RA.

Purpose of the Study:

  • To present a reference atlas of wrist joint MR images for rheumatoid arthritis.
  • To provide standardized reference images for scoring synovitis, bone edema, and bone erosions.
  • To facilitate consistent application of the OMERACT RA MRI scoring (RAMRIS) system for wrist joints.

Main Methods:

  • The study utilized MR images of wrist joints.
  • Reference images were curated for scoring synovitis, bone edema, and bone erosions.
  • Images illustrate all grades (0-3) of synovitis in defined wrist joint areas (distal radioulnar, radiocarpal, intercarpal-carpometacarpal joints).
  • Bone abnormalities were exemplified in selected bones (radius, scaphoid, lunate, capitate, metacarpal base) with illustrations for bone edema (grades 0-3) and bone erosion (grades 0-3 and higher).

Main Results:

  • A comprehensive reference atlas of wrist joint MR images for rheumatoid arthritis is presented.
  • Standardized reference images are provided for assessing synovitis, bone edema, and bone erosions.
  • Illustrations cover all OMERACT RA MRI scoring (RAMRIS) grades for synovitis and bone abnormalities in key wrist structures.

Conclusions:

  • The presented reference images serve as a valuable tool for guiding the scoring of wrist joints in rheumatoid arthritis.
  • This atlas promotes standardized and reproducible MRI assessments in clinical practice and research.
  • Consistent application of the OMERACT RA MRI scoring system is enhanced through this reference image collection.

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Anatomical Movements00:51

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
