Xie R, Sun D, Yin C, et al. - The study was conducted to compare volumetric interpolated breath-hold examination (VIBE) with different slice thicknesses to T1-weighted turbo-echo (T1 TSE) for identification of sacroiliac joint structural lesions in individuals suspected of spondyloarthritis (SpA) utilizing CT as the gold standard. Researchers included a total of 192 sacroiliac joints (including VIBE with both 1.2 mm and 3 mm slice thickness, T1 TSE) from 96 individuals suspected of SpA. For each joint, Joint space changes and sclerosis were assessed. For estimation of sensitivity, specificity, and accuracy, erosions were evaluated both at the level of the individual sacral and iliac bones and at the level of the entire joint. MRI and CT relationship was conducted and inter-reader reliability was ascertained. In individuals with suspected SpA, a VIBE sequence with 1.2 mm slice thickness and less than one-minute acquisition time was superior to T1 TSE for the detection of sacroiliac joint space changes and erosions, while the utility of the 3 mm slice thickness VIBE remains questionable.
