Study design: Observational Study
Abstract: PURPOSE: We investigated the diagnostic accuracy of simplified intravoxel incoherent motion (IVIM) imaging for detecting synovial inflammation in the sacroiliac joint (SIJ) in a population with active sacroiliitis. METHODS: - D were generated voxel by voxel for each patient. The IVIM and ADC parameters at the SIN and SIP joints were compared. RESULTS: , but reasonable for ADC. CONCLUSION: The presence of synovial inflammation in the SIJ can be evaluated with high sensitivity and specificity using only four b values through the simplified IVIM method without the need for a contrast agent. CLINICAL SIGNIFICANCE: IVIM imaging is a technique that allows us to gain insights into tissue perfusion without the administration of contrast agents, utilizing diffusion-weighted images. In this study, for the first time, we demonstrated the potential of detecting synovial inflammation in the SIJ using IVIM, specifically through the pseudodiffusion (D*) parameter, without the need for contrast agents.
