Inclusion The MRI imaging was performed using a 1.5 T Siemens.
Method: Sixty-nine subjects were prospectively included (median age, 42 years; male/female = 32/37) in three cohorts: 10 healthy volunteers, 40 patients with clinically suspected This definition approximates grade 2 knee OA based on the Kellgren and Lawrence scale 36 . MRISubjects were investigated with dGEMRIC 20.6 years (mean; range 18e23) after the injury, using a standard 1.5 T MRI system with a dedicated knee coil (Magnetom Vision; Siemens Medical Solutions, Erlangen, Germany). MRI with dGEMRIC was more sensitive than morphological MRI, and lower dGEMRIC values were found for clock positions with impingement as detected on 3D-CT. This could aid in patient-specific diagnosis of FAI, preoperative patient selection, and surgical decision making to identify patients with cartilage damage who are at risk for inferior outcomes after hip arthroscopy.
Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is an imaging method for detecting early damage to cartilage.
1 ROC-analysis demonstrated non-significant differences of T2 mapping vs CEST (P = 0.14), CEST vs dGEMRIC (P = 0.89), and T2 mapping vs dGEMRIC (P = 0.12). Conclusion: CEST is able to detect normal and damaged cartilage and is non-inferior in distinguishing both when compared to dGEMRIC and T2 mapping. Similar to the knee [ 4, 34 ], dGEMRIC is a promising tool to quantify cartilage healing or degeneration before and after joint-preserving hip surgery and to monitor the natural course of hip diseases. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) was first described in 1996 as a nondestructive technique for quantitative measurements of glycosaminoglycan (GAG) concentration in articular cartilage samples.
The dGEMRIC Index was 14.4% lower in the medial index compartment (374 61 ms, mean SD) than in the lateral reference compartment (437 59 ms, mean SD) (P<0.001). The dGEMRIC Index of the medial diseased compartment correlated positively with both knee flexor (r¼0.50, P¼0.001) and knee extensor

Second, for each of the 4 central thick slices (4 mm thick-ness), the corresponding high resolution dGEMRIC index was calculated from the corresponding 4 thin slices (0.9 mm thickness) and compared. All image analyses were 17 patients with active PsA were evaluated by high-resolution clinical standard morphological and dGEMRIC sequences using a 3T MRI scanner (Magnetom Skyra, Siemens) and a dedicated 16-channel hand coil. Images were analyzed by two independent raters for dGEMRIC indices, PsA MRI scores (PsAMRIS), and total cartilage thickness (TCT). Background: Even though cartilage loss is a known feature of psoriatic arthritis (PsA), little is known about its role in the pathogenesis of PsA. Using delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) as a non-invasive marker of the tissue's proteoglycan content, such early (i.e., pre-morphological) changes have been associated with inflammation in rheumatoid dGEMRIC All patients were investigated in a standard 1.5 T MRI system (MAGNETOM Avanto, Siemens AG, Erlangen, Germany) with two flexibleBody Matrixcoils positioneddirectlyoverthehips.

MATERIALS AND METHODS: The study cohort consisted of 53 patients with symptomatic femoroacetabular impingement (FAI) that were randomly recruited for either iv-dGEMRIC or ia-dGEMRIC studies. RI was performed in supine position at a 1.5 Tesla (T) system (Magnetom Avanto, Siemens, Erlangen, Germany) using a body matrix-phased array coil.
