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.

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. Three-dimensional delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) at 1.5T and 3.0T. J Magn Reson Imaging 2006;24:928-33. Tiderius CJ, Jessel R, Kim YJ, et al. Hip dGEMRIC in asymptomatic volunteers and patients with early osteoarthritis: the influence of timing after contrast injection. The purpose of this study was to assess if delayed gadolinium MRI of cartilage using postcontrast T1 (T1Gd) is sufficient for evaluating cartilage damage in femoroacetabular impingement without using noncontrast values (T10).

This review revealed that dGEMRIC can be reliably used in the evaluation of early stage cartilage pathology in various hip joint disorders. Three-dimensional delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) at 1.5T and 3.0T.
Our study aimed to determine whether dGEMRIC indices are predictive of two-year patientreported outcomes and pain scores following hip arthroscopy. 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

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.

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. We included the ﬁrst 25 hips (23 patients) who had not undergone previous hip surgery and had a complete dGEMRIC scan. This group of patients was identiﬁed 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. 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 .
