Structure-symptom relationship with wide-area ultrasound scanning of knee osteoarthritis.

The aetiology of knee pain in osteoarthritis (OA) is heterogeneous and its relationship with structural changes and function is unclear. Our goal was to determine the prevalence of wide-area scanned ultrasound-defined knee OA structural features and their association with pain and functional impairment in 79 symptomatic and 63 asymptomatic subjects. All subjects underwent ultrasound knee wide-area scanning and the severity of articular cartilage degeneration, the presence and size of osteophytes, and meniscal extrusion were evaluated.

Elevated adiabatic T and T in articular cartilage are associated with cartilage and bone lesions in early osteoarthritis: A preliminary study.

Purpose: To evaluate adiabatic T and T of articular cartilage in symptomatic osteoarthritis (OA) patients and asymptomatic volunteers, and to determine their association with magnetic resonance imaging (MRI)-based structural abnormalities in cartilage and bone.

Materials And Methods: A total of 24 subjects (age range: 50-68 years; 12 female) were enrolled, including 12 early OA patients and 12 volunteers with normal joint function. Patients and volunteers underwent 3T MRI.

Comparison of Diagnostic Performance of Semi-Quantitative Knee Ultrasound and Knee Radiography with MRI: Oulu Knee Osteoarthritis Study.

Osteoarthritis (OA) is a common degenerative musculoskeletal disease highly prevalent in aging societies worldwide. Traditionally, knee OA is diagnosed using conventional radiography. However, structural changes of articular cartilage or menisci cannot be directly evaluated using this method.

In vivo quantitative ultrasound image analysis of femoral subchondral bone in knee osteoarthritis.

A potential of quantitative noninvasive knee ultrasonography (US) for detecting changes in femoral subchondral bone related to knee osteoarthritis (OA) was investigated. Thirty-nine patients referred to a knee arthroscopy underwent dynamic noninvasive US examination of the knee joint. The subchondral bone was semiautomatically segmented from representative US images of femoral medial and lateral condyles and intercondylar notch area.

Ultrasound-guided procedures: techniques and usefulness in controlling inflammation and disease progression.

US allows us to detect joint alterations and to perform procedures such as aspiration of fluid as well as therapeutic injections; it helps in placing the needle correctly, greatly improving the outcome. Tissue biopsies (of, for example, synovium, muscle or salivary glands) can be performed with US guidance, and this method may be of significant importance in diagnostic examinations. Other imaging methods may be fused with US, and thus detailed maps are available to navigate in soft tissues.

Current state of musculoskeletal ultrasound training and implementation in Europe: results of a survey of experts and scientific societies.

Objective: To document the current state of musculoskeletal US (MSUS) training and extent of implementation among rheumatologists in the member countries of EULAR.

Methods: An English-language questionnaire, divided into five sections (demographics, clinical use of MSUS, overall MSUS training for rheumatologists, MSUS education in the rheumatology training curriculum and education in MSUS offered by the national rheumatology society) was sent by e-mail to three different groups: (i) all national rheumatology societies of EULAR; (ii) all national societies of the European Federation of Societies for Ultrasound in Medicine and Biology; and (iii) 19 senior rheumatologists involved in MSUS training from 14 European countries.

Results: Thirty-one (70.

Ability of ultrasound imaging to detect erosions in a bone phantom model.

Objectives: The authors examined the validity, interobserver reliability and interscanner variation in detecting bone erosions with ultrasonography using a custom-made phantom.

Methods: 21 bovine bones were used. Artificial erosions were made into 15 bones and six bones were left as controls.

The OMERACT Ultrasound Group: status of current activities and research directions.

Ultrasound (US) is a relatively new imaging modality in rheumatology that offers great potential as a diagnostic and management tool. In 2004, an OMERACT Ultrasound Special Interest Group was formed to address the metric qualities of US as a potential outcome measure. A preliminary systematic review highlighted the deficiencies in the literature, particularly with regard to the reliability of interpreting and acquiring images; as a consequence, a number of exercises were proposed to address these issues.
