The Hong Kong Society of Rheumatology (HKSR) has developed evidence-based position statements on the use of magnetic resonance imaging (MRI) in axial spondyloarthritis (axSpA). A special interest group (SIG) developed the statements based on the literature review of the following research questions: 1) In whom should SI joint MRI be done to diagnose axSpA? 2) Should spine MRI be performed for diagnosis of axSpA? 3) Should spine and SI joint MRI be used in the assessment and monitoring of disease activity? 4) Which MRI sequence(s) should be used in axSpA? These statements have at least 75% agreement from voting rheumatology fellows of HKSR, and are developed to serve as local practice guidelines for rheumatologists and musculoskeletal radiologists in the management of axSpA.

Our aim was to determine the prevalence of spine and sacroiliac joint (SIJ) lesions on magnetic resonance imaging (MRI) in patients with early axial spondyloarthritis (axSpA) and their correlation with disease activity indices. Sixty patients with low back pain (LBP) (≥3 months, ≤2 years, onset ≤45 years), attending the SpA-clinic of the Unità Operativa Complessa Reumatologia of Padova [SpondyloArthritis-Caught-Early (SPACE) study], were studied following a protocol including physical examination, questionnaires, laboratory tests, X-rays and spine and SIJ MRI. Positive spine and SIJ MRI and X-rays images were scored independently by 2 readers using the SPARCC method, modified Stoke ankylosing spondylitis spine score and New York criteria. The axial pain and localization of MRI-lesions were referred to 4 sites: cervical/thoracic/lumbar spine and SIJ. All patients were classified into three groups: patients with signs of radiographic sacroiliitis (r-axSpA), patients without signs of r-axSpA but with signs of sacroiliitis on MRI (nr-axSpA MRI SIJ+), patients without signs of sacroiliitis on MRI and X-rays (nr-axSpA MRI SIJ-). The median age at LBP onset was 29.05±8.38 years; 51.6% of patients showed bone marrow edema (BME) in spine-MRI and 56.7% of patients in SIJ-MRI. Signs of enthesitis were found in 55% of patients in the thoracic district. Of the 55% of patients with BME on spine-MRI, 15% presented presented a negative SIJMRI. There was a significant difference between these cohorts with regard to the prevalence of radiographic sacroiliitis, active sacroiliitis on MRI and SPARCC SIJ score. The site of pain correlated statistically with BME lesions in thoracic and buttock districts. Since positive spine-MRI images were observed in absence of sacroiliitis, we can hypothesize that this finding could have a diagnostic significance in axSpA suspected axSpA.

Objective.The volumetric interpolated breath-hold examination (VIBE) magnetic resonance imaging (MRI) technique can visualize erosive cartilage defects in peripheral joints. We evaluated the ability of VIBE to detect erosions in sacroiliac joints (SIJ) of patients with axial spondyloarthritis (axSpA) compared to the established T1-weighted MRI sequence and computed tomography (CT).Methods.MRI (T1-weighted and VIBE) and CT scans of SIJ of 109 patients with axSpA were evaluated by 2 blinded readers based on SIJ quadrants (SQ). Erosions were defined according to Assessment of Spondyloarthritis international Society (ASAS) definitions. Scores were recorded if readers were in agreement.Results.Erosions were less frequently detected by CT (153 SQ) than by T1-weighted MRI (182 SQ; p = 0.008) and VIBE-MRI (199 SQ; p < 0.001 vs CT and p = 0.031 vs T1-weighted MRI). Taking CT as the gold standard, the sensitivity of VIBE-MRI (71.2%) was higher than that for T1-weighted MRI (63.4%), with similar specificity (87.3% vs 88%, respectively). In linear regression analysis, younger age was significantly associated with occurrence of erosions independently in VIBE-MRI (β = 0.384, p < 0.001) and T1-weighted MRI (β = 0.369, p < 0.001) compared to CT.Conclusion.The VIBE-MRI sequence was more sensitive than T1-weighted MRI in identifying erosive damage in the SIJ, especially in younger patients. This might be due to the ability of VIBE-MRI to identify structural changes in the cartilage that have not yet extended to the underlying bone, where CT seems to be superior.

Introduction: Magnetic resonance imaging (MRI) is a fundamental diagnostic tool in axial spondyloarthritis, it has allowed us, unlike radiography, to diagnose this pathology much earlier. Objective: To estimate the percentage of correct answers in the recognition of SpA MRI lesions and theoretical knowledge, before and after performing an educational intervention. Estimate if the good performance in the tests is associated with individual characteristics of the doctors. Methods: A test was carried out with 10 questions (7 for image recognition and 3 for theoretical knowledge) before and after the development of an MRI image workshop in EspA in diferents cities in Argentina. The correct response number was considered before and after the workshop, and those who achieved more than 12 points between the two evaluations were considered good performance. The following physician characteristics were collected. Results: A total of 106 physicians were evaluated. The results of the tests (total 10 questions) before and after the workshop were 53% and 68% correct, respectively (p:0.000). 65% of the physicians achieved a good performance (more than 12 correct).

Over the past decade, advances in neuroimaging have given birth to a new field of diagnostic pediatric neurologic assessment that includes magnetic resonance imaging (MRI). This invaluable tool helps medical professionals to resolve many clinical and research questions related to neonatal neurodevelopment that other imaging technology cannot explain. Nurses and others who accompany infants to MRI would benefit from a better understanding of early neurodevelopment and of the neuroimaging procedure. Knowing the advantages and disadvantages of MRI techniques can help nurses be better patient advocates, parent liaisons, and caregivers to infants having MRI scans.

Background:The inflammatory of the sacroiliac joints (SIJs) called sacroiliitis, is a characteristic of axial Spondyloarthritis (axSpA). The detection of sacroiliitis is meaningful to prevent irreversible changes. The tool of assessment of sacroiliitis including radiographs, computed tomography (CT) and magnetic resonance imaging (MRI). Ultrasound (US) has also been used in the evaluation of sacroiliitis in recent years.Objectives:We aimed to evaluate the value of US in the assessment of active sacroiliitis in axSpA patients.Methods:Fifty-one patients fulfilling Assessment of SpondyloArthritis International Society (ASAS) 2009 criteria for the classification of axSpA were recruited1. All the patients underwent MRI and US evaluation of bilateral SIJs. MRI was performed using the sequences of T1WI, T2WI and fat suppression T2WI (FS-T2WI). MRI sacroiliitis was defined according to ASAS criteria of active sacroiliitis2. The Spondyloarthritis research Consortium of Canada (SPARCC) scoring was used to evaluate the inflammatory lesions in SIJs3. US were performed by an ultrasonographer with 10 years of experience in musculoskeletal ultrasound, and resistive index (RI) value was recorded. The US sacroiliitis was defined as the presence of more flow signals at SIJ with an RI ≤ 0.75. The HLA-B27, erythrocyte sedimentation rate (ESR) and hypersensitive C-reactive protein (hsCRP) were also evaluated. Consistency rate, sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV)for the diagnosis of sacroiliitis by US were calculated, using MRI as the gold standard.Results:Of the 51 patients, 24 were female and 27 were male. The HLA-B27 positive rate was 90.2% (46/51). The consistency rate of US and MRI sacroiliitis was 55.88 (57/102). The sensitivity and specificity of US for the diagnosis of sacroiliitis were 55.93 (33/59) and 55.81 (24/43) respectively. The PPV and NPV were 63.46 (33/52) and 48 (24/50) respectively. There was no significant difference in ESR and hsCRP between the US positive sacroiliitis and the others (P= 0.7477 and 0.2268, respectively). The SPARCC scores have no significant difference between the US positive sacroiliitis and the others (P= 0.2206). The RI was not significantly associated with the MRI SPARCC score (P=0.4236).Conclusion:US may be an optional method for preliminary screening sacroiliitis. But its reliability as a diagnostic method needs further verification.References:[1]Rudwaleit M, et al.
