Examining the validity of the rheumatoid arthritis magnetic resonance imaging score according to the OMERACT filter-a systematic literature review.

Objective: To examine whether the RA MRI score (RAMRIS) for RA of the wrist/hand meets the OMERACT filter criteria-truth (validity), discrimination and feasibility. Methods: We conducted a systematic literature review in PubMed and Scopus, from 1970 through June 2014, focused on MRI measures of synovitis, osteitis/bone marrow oedema, erosions and/or joint space narrowing in RA randomized controlled trials and observational studies with cohort size ⩾10. Strength of evidence was assessed using the Cochrane Handbook criteria. Results: Of 634 MRI titles/abstracts, 202 met the review criteria, with 92 providing at least 1 type of validity. Four articles provided criterion validity, and 26 articles utilized RAMRIS to assess 1.5 T MRI images. Histopathology data showed inflammation corresponding to MRI of synovitis and osteitis. MRI erosions corresponded to those identified with CT. Content and construct validity for RAMRIS synovitis, osteitis and erosions were documented by correlations with clinical, laboratory and/or radiographic data. Each measure was sensitive to change and responsive to therapy. RAMRIS synovitis and osteitis were able to discriminate between the efficacy of treatments vs placebo in 12-week studies, whereas RAMRIS erosions required studies of ⩾24 weeks. Conclusion: RAMRIS synovitis, osteitis and erosions imaged with 1.5 T MRI are valid and useful for evaluating joint inflammation and damage for RA of the wrist/hand, according to the OMERACT filter.

Proceedings from The 8th Annual International Society for Musculoskeletal Imaging in Rheumatology (ISEMIR) Conference.

The International Society for Musculoskeletal Imaging in Rheumatology (ISEMIR) was founded in 2005 with the goal of discussing matters related to imaging in rheumatology, particularly, validation, education, and use in both clinical practice and research. The field of musculoskeletal (MSK) imaging is continuously evolving; therefore, education for healthcare providers in this field is of paramount importance. ISEMIR's international faculty and world-renowned experts presented the newest information as it relates to the use of magnetic resonance imaging (MRI) and ultrasound (US) at the 8th annual ISEMIR meeting that took place on April 17-18 in Santa Monica, California. Presentations from the meeting can be viewed at www.isemir.org.

Magnetic resonance imaging applications in early rheumatoid arthritis diagnosis and management.

Early diagnosis and treatment have been recognized as essential for improving clinical outcomes in patients with rheumatoid arthritis (RA). Magnetic resonance imaging (MRI) is a sensitive modality that can assess both inflammatory and structural lesions. MRI can assist in following the disease course in patients treated with traditional disease-modifying antirheumatic drugs and biological therapies both in the clinic and in research trials. Therefore, it is anticipated that MRI becomes the diagnostic imaging modality of choice in RA clinical trials while remaining a useful tool for clinicians evaluating patients with RA.

Proceedings of the 2012 Rheumatology Winter Clinical Symposia.

Recent years have witnessed important developments in rheumatology. Novel diagnostic methods, stratification approaches, and treatment paradigms have been brought into the clinic for a number of rheumatologic and autoimmune diseases. In addition, there have been developments in related medical disciplines that are relevant to the care of patients with rheumatic diseases. Keeping pace with these many developments is a challenge, and clinical rheumatologists have used various methods to educate themselves about these advances. In January 2012, the 5th annual Rheumatology Winter Clinical Symposium was held. At this meeting, faculty and participants held discussions and exchanged knowledge about new scientific data and how it may impact the care of rheumatology patients. Excerpts from some of the lectures from the Rheumatology Winter Clinical Symposium 2012 are included in this review. These and other presentations can be viewed in their entirety at http://www.r-w-c-s.com.

Magnetic resonance imaging is more sensitive than radiographs in detecting change in size of erosions in rheumatoid arthritis.

OBJECTIVE: To evaluate the technological performance of magnetic resonance imaging (MRI) with respect to projection radiography by determining the incidence of changes in the size of individual bone lesions in inflammatory arthritis, using serial high-resolution in-office MRI over short time intervals (8 months average followup), and by comparing the sensitivity of 3-view projection radiography with in-office MRI for detecting changes in size and number of individual erosions. METHODS: MR examinations of the wrists and second and third metacarpophalangeal joints were performed using a portable in-office MR system in a total of 405 patients with inflammatory arthritis, from one rheumatologist's practice, who were undergoing aggressive disease modifying antirheumatic drug therapy. Of the patients, 156 were imaged at least twice, allowing evaluation of 246 followup examinations (mean followup interval of 8 months over a 2-year period). Baseline and followup plain radiographs were obtained in 165 patient intervals. Patients refused radiographic examination on 81 followup visits. RESULTS: MRI demonstrated no detectable changes in 124 of the 246 (50%) followup MRI examinations. An increase in the size or number of erosions was demonstrated in 74 (30%) examinations, a decrease in the size or number of erosions in 36 (15%), and both increases and decreases in erosions were seen in 11 (4%). In the 165 studies with followup radiographic comparisons, only one examination (0.8%) showed an erosion not seen on the prior examination and one (0.8%) showed an increase in a previously noted erosion. CONCLUSION: We showed that high-resolution in-office MRI with an average followup of 8 months detects changes in bony disease in 50% of compliant patients during aggressive treatment for inflammatory arthritis in a single rheumatologist's office practice. Plain radiography is insensitive for detecting changes in bone erosions for this patient population in this time frame.

Identification of wrist and metacarpophalangeal joint erosions using a portable magnetic resonance imaging system compared to conventional radiographs.

OBJECTIVE: To compare magnetic resonance (MR) images obtained using a portable MR system to radiographs for identifying bone erosions in the wrists and metacarpophalangeal (MCP) joints of patients with inflammatory arthropathy. METHODS: MR imaging and radiographs were performed in wrists (n = 227) and 2nd and 3rd MCP (n = 188) of 132 patients with inflammatory arthritis to identify erosions. MR imaging was performed using a portable MR system. Findings per body location and per patient were calculated and compared. Additionally, intraobserver and interobserver reliabilities were calculated. RESULTS: MR imaging identified bony erosions in 125 (95%) patients and in 315 (78%) body locations. By comparison, radiographs identified erosions in 78 (59%; p < 0.05) patients and in 156 (39%; p < 0.05) body locations. Intraobserver reliability (K = 0.564) and interobserver reliability (K = 0.429) exhibited moderate agreement, with reader agreement in 80% of the joints scored. CONCLUSION: There was superior sensitivity to bone damage using the portable MR system compared to radiographs of the wrists and MCP joints, suggesting that this scanner is extremely promising for assessment of inflammatory arthritis.

The young adult with hip pain: diagnosis and medical treatment, circa 2004.

Hip pain in young adults (18-35 years old) often is characterized by nonspecific symptoms, normal imaging studies, and vague findings from the history and physical examination. In younger patients, pain is more likely to be caused by congenital hip dysplasia, athletic injuries, trauma, spondyloarthropathy, and by conditions that first appear during this stage of life, such as rheumatoid arthritis, osteoarthritis, intravenous drug use, alcoholism, or corticosteroid use. The history and physical examination may narrow the diagnosis to intraarticular, extraarticular, or referred sources of pain. Plain radiography and magnetic resonance imaging are the preferred initial imaging procedures. Analyses of the blood, urine, and synovial fluid can be helpful in diagnosing inflammation, infection, and systematic rheumatic disease. Fractures, infection, and ischemic necrosis should be ruled out early because they require immediate treatment to prevent damage to the joint. Hip trauma at a young age increases the risk of osteoarthritis with advancing age, and, unlike most older adults, young adults receiving total hip replacement can expect revision surgery. Medical treatment often involves patient education, physical therapy, and pharmacotherapy. Acetaminophen, nonsteroidal anti-inflammatory drugs, and opioids for pain and antibiotics for infection are the most often prescribed drugs for this population.
