dGEMRIC is a clinically applicable MRI method that may improve identification of early subtle cartilage damage and the accuracy of volume measurements of hip joint cartilage. 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. 2009-06-11 2014-10-01 2012-07-01 scan and MRI scan with dGEMRIC of the same hip joint for diagnosis of anterior FAI and evaluation for hip preser-vation surgery between April 2013 and November 2016.

Kim, D. Burstein 1Department of Radiology, Beth Israel Medical Center, Boston, MA, United States, 2Department of Orthopedics, Children's Hospital, Boston, MA, United States Introduction: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a molecular imaging technique that 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). 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.

Boston, Boston, MA;2Dept. of Orthopedics, Bern, Switzerland Purpose:Aberrant hip anatomy as found in developmental dyspla-sia of the hip (DDH) or femoroacetabular 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. For ia‐dGEMRIC, 10–20 mL of a 2 mM solution of Gd‐ DOTA− was injected under fluoroscopic guidance 30 min before the MRI scan. Results Both ia‐ and iv‐dGEMRIC demonstrated the typical T1Gd pattern in hip joint cartilage with increasing values toward the superior regions in acetabular cartilage reflecting the higher glycosaminoglycan Materials and Methods.

Participants with hip pain prospectively (July 2019–January 2020) underwent indirect MR arthrography (with intravenous administration of 0.2 mmol/kg of gadoterate meglumine), including 3D MP2RAGE MRI. Perifoveal cartilage injury in fovea alta evaluated on dGEMRIC may be an important marker of foveal acetabular impingement in hip dysplasia.

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. dGEMRIC requires intravenous injection of gadolinium contrast, however, which adds time, expense, and The reproducibility of hip dGEMRIC measured at 30 min post-contrast shows CV% on the order of 15 % . However, with standardization of timing of image acquisition and exercise routine and with the use of more rapid T1 acquisition, the reproducibility can be improved to 5–8 % in the hip and 4–7 % in the knee .
