Purpose: To assess the feasibility of performing intra-articular dGEMRIC in patients scheduled for MR arthrography of the hip joint, specifically to evaluate whether using fixed amount of contrast agent and applying additional medications to joint cavity influence the dGEMRIC index.
Materials and methods: Thirty-nine patients with hip pain, who had standard MR imaging of hip joint and longitudinal relaxation time (T1) mapping data following intra-articular administration of gadopentetate (Gd-DTPA2-) on either a 1.5T or 3.0T scanner, were reviewed. The T1s of articular cartilage and synovial fluid were analyzed with two-tailed t-test and regression analysis based on the presence or absence of morphological cartilage damage. A phantom study to mimic the synovial fluid changes during arthrography procedure was performed.
Results: T1 measured in damaged cartilage was s.. View More»
