AU - Warfield, Simon K. 2010-05-01 There are a few techniques to look at cartilage health; on is called a dGEMRIC scan and another is called T2 mapping. dGEMRIC stands for delayed gadolinium-enhanced MRI of cartilage. When the dGEMRIC index is low, then the chance of success is decreased.

The preoperative dGEMRIC scan shows the superficial zone with lower dGEMRIC index, as indicated by the arrow. dGEMRIC assessment dGEMRIC images were obtained for the study hip on a 3T scanner (Philips Integra) at a single centre. Subjects received intravenous injection of 0.4 ml/kg of Gd-DTPA2- contrast agent (Bayer AG, Leverkusen, Germany) and then performed 10 minutes of weightbearing exercise. MRI Scans explained, Patient Guide. MRI Scanner uses a powerful magnet & radio waves to produce detailed views of the human body, Melbourne Radiology Clinic 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. Per MRI scan several regions-of-interest (ROI) were defined for different locations in the joint.

A dGEMRIC index (T1Gd) was used for changes in cartilage glycosaminoglycan content, a high T1Gd indicating a high glycosaminoglycan content and vice versa. 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.
Knee cartilage quality assessed with dGEMRIC in rheumatoid
The anterior center-edge angle, the joint space The biochemical information provided by dGEMRIC scans may augment radiography by improving the differentiation of disease status within a given radiographic grade, especially in early OA. 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. 2015-04-24 · Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is an imaging technique to estimate joint cartilage. dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage . It is a recent technique where an MRI scan dedicated to detecting early cartilage breakdown is performed. (interpolated to 512 x 512), 3 mm slice thickness, 20 slices. Scan time was approximately 35 minutes.

A pancreas scan uses nuclear radiology to search for, and sometime treat, tumors in the pancreas.
In particular, molecular scans such as dGEMRIC have demonstrated “lesions” or generally low values in radiographically normal compartments [51, 62, 64], which has implications for the enrollment of such individuals as “controls” in natural history or intervention trials for cartilage disease. 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.
Per MRI scan several regions-of-interest (ROI) were defined for different locations in the joint. 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
After scout images, dGEMRIC scans were performed on a clinical 3-tesla MRI scanner (Achieva 3T; Philips Medical Systems) using a 16-channel knee coil. The first dGEMRIC protocol was initiated 90 minutes after contrast administration.The dGEMRIC scans were performed of the ACL-injured and contralateral uninjured knees sequentially.

The following radiographic measurements were performed to determine acetabular and femoral morphology: lateral center edge angle Methods: Ninety-six symptomatic dysplastic hips in seventy-four patients were assessed with standard radiographs and a dGEMRIC scan. The lateral center-edge angle of Wiberg, the acetabular index of Tönnis, and the break in the Shenton line were measured on a standing anteroposterior radiograph. 2013-07-01 · 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. The primary aim of this study was to show that the dGEMRIC technique is able to monitor cartilage repair following regenerative cartilage treatment.
