• TE = time to echo in milliseconds • FS = fat suppressed • Int = intermediate • Int FS: this is a fat suppressed sequence with a long TR and a TE between that of a traditional PD (e.g. TE= 10-20) and a traditional T2 (e.g. TE=80-100). The advantage of this sequence is that the TE is short
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.
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.
17 sie 2024 · Pain in the sacroiliac (SI) region is a common clinical manifestation frequently caused by diseases involving the SI joints. Approximately twenty-five percent of the cases of lower back discomfort are due to sacroiliitis, an inflammation of the SI joint, the largest axial joint in the human body.
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.
A complete diagnostic MRI examination of the sacroiliac joints (SIJ) is required. Two sequences are required for scoring and classification purposes.
6 kwi 2024 · SIJ imaging is crucial for diagnosing and monitoring axial spondyloarthropathies. Imaging tools like radiographs, CT scans, and MRI are valuable, with MRI being especially effective in early inflammatory sacroiliitis detection.
