After MRI, bone-cartilage samples were taken from the acetabulum and the femur and stained with toluidine blue for assessment of the Eight asymptomatic volunteers and 10 patients with early hip osteoarthritis (OA) were investigated with hip delayed gadolinium‐enhanced MRI of cartilage (dGEMRIC) at 30, 65, 100, and 135 min after IV injection with Gd‐DTPA 2–. In asymptomatic volunteers there was a decrease in the dGEMRIC index (T 1 (Gd)) between 30 and 100 min. Objective. To assess the pattern of cartilage damage in symptomatic cases of developmental dysplasia of the hip (DDH) and of femoroacetabular impingement (FAI) with a novel three-dimensional (3D) delayed Gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) technique. Background . Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a validated technique for evaluating cartilage health in developmental dysplasia of the hip (DDH), which can be a helpful prognosticator for the response to surgical treatments.

QUESTION/PURPOSE In this study, our purpose was to determine the correlation between the relaxation values of three cartilage mapping techniques, dGEMRIC, T1ρ, and T2*, in patients with DDH. MRI was performed with a 3T system wherein the interval between both measurements was 2 weeks.

Delayed gadolinium enhanced MRI of cartilage (dGEMRIC) permits inference of glycosaminoglycan (GAG) distribution in articular cartilage from measurements of the tissue T1 value after injection of the MRI contrast agent gadolinium (1). dGEMRIC, or delayed gadolinium-enhanced MRI of cartilage is a technique that can be used quantitatively to assess glycosaminoglycan content of cartilage or qualitatively to asses the overall structures of cartilage. When the technique is adapted and applied to menisci it is called dGEMRIM. symptomatic hips undergoing a contrast-enhanced MRI at 3T including a 3-D dGEMRIC sequence to assess intra-articular pathology due to structural hip deformities at a tertiary care center.

The majority of dGEMRIC studies have been in the knee and hip, although there are a number of reports of dGEMRIC applied to the finger joints [12, 50–52] and ankle . dGEMRIC protocols have also been applied in the meniscus [54–56] and intervertebral discs [57, 58]; however, the considerations of transport are much more of a concern in these thick tissues, and the interpretation of the studies is likely to be different than those in the articular cartilages.

Newer MRI cartilage mapping techniques such as T1 rho (ρ) and T2* have been performed in the hip without the need for any contrast, although it is unknown whether they are equivalent to dGEMRIC. QUESTION/PURPOSE In this study, our purpose was to determine the correlation between the relaxation values of three cartilage mapping techniques, dGEMRIC, T1ρ, and T2*, in patients with DDH. The dGEMRIC MRI requires an injection of a contrast agent, while the T1-rho MRI does not. If the T1-rho is shown to be as useful as the dGEMRIC method it can then be used to look at cartilage damage in the hip without having to have an injection. nonarthrographic hip MRI protocol is outlined in Table 1.6 Comprehensive Interpretation of Hip MRI Bone Morphologic Characteristics MRI is optimized for soft-tissue characterization, and detailed evaluation of cortical bone is limited because of low relative proton density.
