(interpolated to 512 x 512), 3 mm slice thickness, 20 slices. Scan time was approximately 35 minutes. To attain sufficient signal-to-noise at the short TIs, TR shot was held constant at 1700 ms for each TI. dGEMRIC Analysis: All 3D scans were volume registered prior to analysis to compensate for any subject movement during the examination.

Research output: Contribution to journal › Article The dGEMRIC index was calculated as the average T1 value of the acetabular and femoral head cartilages in the weight‐bearing zone (as designated from the edge of the acetabular rim to the indentation at the site of fovea's attachment to the femoral head) across all four coronal slices. 1 Radiograph and dGEMRIC scan of a 42‐year‐old patient with bilateral femoroacetabular impingement.

Because scan order did not influence the dGEMRIC indices, the contralateral uninjured knee can be used as a matched control for investigating cartilage health in ACL-injured patients. The cross-sectional sample of the present study also allowed us to explore the changes in dGEMRIC indices of the medial compartment with respect to time from injury.

Design Thirty-one patients with a focal cartilage lesion underwent a dGEMRIC scan prior to cartilage repair surgery and at 3 and 12 months follow-up. At similar time points clinical improvement was monitored using the KOOS and Lysholm questionnaires.

motion artifacts, standard MRI and dGEMRIC scans were performed pre-operatively and at 2,4,8,12,16 weeks post-operatively.

Regression analysis demonstrated that among factors such as age, LCE, JSW, subluxation, Tönnis grade, joint congruency, and pre-op dGEMRIC index only pre-op dGEMRIC index and Tönnis grade were significantly associated with the change in dGEMRIC index after Clinical examination, serum COMP level, and dGEMRIC scans (1.5 T) were performed at baseline and after 7 months. The dGEMRIC index (ms), reflecting cartilage GAG content, was calculated using an inversion recovery sequence in the femoral weight-bearing cartilage. OBJECTIVE Delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) facilitates non-invasive evaluation of the glycosaminoglycan content in articular cartilage.

p.467-478. Mark; Abstract Three-dimensional (3-D) delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) helps quantify … The dGEMRIC scans were obtained after a double dose (0.4 mL/kg) intravenous injection of FDA approved contrast agent Magnevist (Gd-DTPA2-; Berlex Laboratories, Wayne, New Jersey). Patients were required to walk 15 min prior to scan.

Patients with general contraindica-tions for MRI scanning, a known allergic reaction to gadolinium-containing contrast agents or with a history of kidney pathology wereconsiderednoteligibleforinclusion.If,duringarthroscopy,the treating physician found that the lesion or other cartilage surfaces Design: Ten patients with medial compartment osteoarthritis underwent a dGEMRIC scan prior to HTO, and after bone healing and subsequent hardware removal. A dGEMRIC index (T1Gd) was used for changes in cartilage glycosaminoglycan content, a high T1Gd indicating a high glycosaminoglycan content and vice versa.

The delayed Gadolinium Enhanced MRI of Cartilage (dGEMERIC) is a functional MRI technique that was designed to detect the loss of the charged extracellular matrix in cartilage in early OA (1, 2). Cartilage fixed‐negative‐charge density is composed of negatively charged glycosaminoglycans.

2012-10-01 · Ten patients with medial compartment osteoarthritis underwent a dGEMRIC scan prior to HTO, and after bone healing and subsequent hardware removal. A dGEMRIC index (T1 Gd) was used for changes in cartilage glycosaminoglycan content, a high T 1 Gd indicating a high glycosaminoglycan content and vice versa.

For all sites, a significant decrease in T1 relaxation times occurred between precontrast scans and 30, 60, 120, and 180 min scans of the dGEMRIC series (P < 0.0001). 2018-05-16 · In our implementation, dGEMRIC using IR required a longer scan time at 7 T compared to at 1.5 T. The reason is that we, as we expected longer T 1 s at the higher field strength, chose to increase the repetition time and add an extra acquisition with longer TI at 7 T. Background Lesions in the meniscus are risk factors for developing knee osteoarthritis (OA), not least because of the role of the meniscus in the pathological progression of OA. Delayed gadolinium enhanced MRI of cartilage (dGEMRIC) has extensively been used to identify pre-radiographic cartilage changes in OA. In contrast, its counterpart with regard to examination of the meniscus, gadolinium OBJECTIVE: Delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) facilitates non-invasive evaluation of the glycosaminoglycan content in articular cartilage. The primary aim of this study was to show that the dGEMRIC technique is able to monitor cartilage repair following regenerative cartilage treatment. Planar dGEMRIC Maps May Aid Imaging Assessment of Cartilage Damage in Femoroacetabular Impingement.

For each scan, T1 relaxation times were calculated using five regions of interest (sites 1-5) in the cartilage. For all sites, a significant decrease in T1 relaxation times occurred between precontrast scans and 30, 60, 120, and 180 min scans of the dGEMRIC series (P < 0.0001).

For the even-numbered subjects, the uninjured knee was scanned first. Per MRI scan several regions-of-interest (ROIs) were defined for different locations in the joint. The dGEMRIC index (T1gd) was calculated for each ROI. Repeated-measures analysis of variance (RMANOVA) analysis was used to evaluate improvement in clinical scores and MRI T1gd over time. dGEMRIC protocol was initiated 90 min after contrast administration. The dGEMRIC scans were performed of the ACL-injured and contralateral uninjured knees sequentially.

In addition to these picture-only galleries, you  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. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) enables non-invasive assessment of cartilage glycosaminoglycan content. This study aimed to evaluate if dGEMRIC could detect relevant changes in cartilage glycosaminoglycan content following HTO. Delayed gadolinium enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) facilitates non-invasive evaluation of the glycosaminoglycan content in articular cartilage. The primary aim of this study was to show that the dGEMRIC technique is able to monitor cartilage repair following regenerative cartilage treatment.
