This review outlines the imaging approach to sacroiliitis, emphasizing the imaging protocols, diagnostic criteria, limitations and potential mimics of MRI examination. The value of imaging-guided intervention in sacroiliac joint disease is also briefly outlined.
17 sie 2024 · Imaging findings typical of SpA at the sacroiliac joints include subchondral erosions and sclerosis, fatty bone marrow replacement at the sites of previous sacroiliitis, BME surrounding the SI joint as a sign of active inflammation, and ultimately, the ankylosis of the SI joints .
30 cze 2024 · Sacroiliitis (rare plural: sacroiliitides) is an inflammation of one or both sacroiliac (SI) joints. It is a common cause of buttocks or lower back pain and can manifest as a wide range of disease processes. Clinical presentation. Symptoms of sacroiliitis can vary.
9 mar 2024 · We present a summary of practice recommendations for imaging of sacroiliitis, including several new imaging techniques. Key Points • MRI is the modality of choice for suspected inflammatory sacroiliitis, including a joint-line-specific sequence for optimal evaluation of the bone-cartilage interface to improve detection of erosions.
3 sty 2024 · One key application lies in diagnostic imaging, where AI algorithms can meticulously analyze X-rays, CT scans, and MRIs to identify and quantify indicators of sacroiliitis, including subtle changes in the sacroiliac joints and inflammatory markers like bone marrow edema .
5 mar 2024 · The ASAS classification criteria were developed for population selection for research with clinical, biochemical, genetic, and imaging criteria 1-4. The sensitivity and specificity of the ASAS classification criteria are around 80% 4,5 , which limits its use as a diagnostic tool 4 .
6 sie 2024 · A standardised IAP for SIJ MRI for diagnostic ascertainment of sacroiliitis is recommended and should be composed of at least four sequences that include imaging in two planes and optimally visualise inflammation, structural damage and the bone-cartilage interface.
