2016-02-11 A literature search was performed with PubMed, using the terms "cartilage, osteoarthritis, hip joint, MRI, and dGEMRIC", considering all levels of studies. This review revealed that dGEMRIC can be reliably used in the evaluation of early stage cartilage pathology in various hip joint disorders.

Delayed gadolinium-enhanced. MRI of cartilage (dGEMRIC) is a previously presented method for identification by loss and degradation of cartilage, commonly affecting the knees and hips.

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.

Despite this limitation, cortical bone is sufﬁciently imaged on MRI Delayed gadolinium-enhanced magnetic resonance imaging of cartilage or dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage using the spin-lattice relaxation time or T1 relaxation time. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a method to assess cartilage quality by measuring the content of glucosaminoglycans (GAG) [1]. The GAG content is estimated by measuring cartilage T1 values in the presence of the contrast agent Gd-DTPA2-(T1 Gd). A previous study on patients with hip dysplasia, a Our cohort included 25 males and 20 females with a mean +/- SD age at surgery of 29 +/- 11 years.

Lund University - ‪‪Cited by 1773‬‬ - ‪MRI‬ - ‪Magnetic resonance imaging‬ dGEMRIC (delayed gadolinium‐enhanced MRI of cartilage) indicates for three‐dimensional variable flip angle T1 measurements in hip dGEMRIC at 3 T and 1.5 T.

Planar dGEMRIC maps were generated from isotropic, sagittal oblique TrueFISP and T1 sequences. A pediatric musculoskeletal radiologist with experience in hip MRI evaluated studies using radially reformatted sequences. Patterns of cartilage change in FAI patients are more accurate and better visualized in dGEMRIC, suggesting a higher sensitivity compared to standard MRI (17, 18). dGEMRIC has been validated by previous studies, showing that it is able to detect patterns of cartilage changes in patients with and at risk of hip and knee OA (19-22).

Methods: In this IRB-approved, retrospective, diagnostic study, we identified the first 25 symptomatic hips (23 patients) who underwent a contrast-enhanced MRI at 3T including a 3-D dGEMRIC sequence for intraarticular pathology assessment due to structural hip deformities. Due to its ability to assess the soft tissues and cartilage that are damaged in early OA, magnetic resonance imaging (MRI) has become the preferred diagnostic tool in pre-operative assessment in hip preservation surgery7. OBJECTIVE: The aim of this study was to evaluate differences in damage patterns assessed using magnetic resonance imaging (MRI) between hips with femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) as well as to correlate MRI findings with delayed Gadolinium enhanced MRI of cartilage (dGEMRIC) and with patient pain.

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.

noninvasive method for assessing localized cartilage degeneration at the hip. 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).
