The “delay” refers to the time that is required for the contrast agent to diffuse into the cartilage after an intravenous (IV) injection. In femoral knee cartilage, T1 Gd was found to be relatively stable at 90–120 min postinjection, which has been the recommended window for dGEMRIC imaging of the knee [8, 11].In the hip joint, early data indicated no difference in signal intensity in T1

dGEMRIC protocols have also been applied in the meniscus [54–56] and intervertebral discs [57, 58]; however, the considerations of transport are much more of a concern in these thick tissues, and the interpretation of the studies is likely to be different than those in the articular cartilages.

The camera displays pictures on a video monitor, and your surgeon uses these images to guide miniature surgical instruments. Popular articular surface injury is in the knee with an acute anterior cruciate ligament ( ACL) tear. MRI of cartilage (dGEMRIC) are more promising than mor- phological imaging of cartilage (dGEMRIC) in the quantification of tent in vivo in patients with knee osteoarthritis, whereas T1ρ hanced MRI of cartilage (dGEMRIC).

2014-01-01 · MRI. Subjects were investigated with dGEMRIC 20.6 years (mean; range 18–23) after the injury, using a standard 1.5 T MRI system with a dedicated knee coil (Magnetom Vision; Siemens Medical Solutions, Erlangen, Germany). Initially, Gd-DTPA 2− (Magnevist ®, Schering AG, Berlin, Germany) was injected at a dose of 0.3 mmol/kg body weight.

Background: We sought to replace full-dose Gd-DTPA with safer and lower-dose contrast agents for delayed gadolinium-enhanced MRI of cartilage (dGEMRIC). Gd-BOPTA has a lower intrinsic nephrogenic systemic fibrosis risk and a 2-fold higher relaxivity at 3T; thus, the contrast agent dose may be halved, further reducing contrast agent-dependent risks. MRI measurements were performed in femoral knee cartilage pre- & post-injection of Gd-DTPA2-.

Seventeen knees in 15 patients (age 35–70) with arthroscopically verified cartilage changes (softening and fibrillations) in the medial or lateral femoral compartment, knee pain, and normal weight‐bearing radiography were included. Quantitative MRI analysis, in the form of delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) relies on the relationship between the highly negatively charged glycosaminoglycans (GAG) and the negatively charged MRI contrast agent gadolinium, providing a measure of quality of the cartilaginous tissue, specifically with regard to GAG content.

Current research is investigating the clinical application of dGEMRIC as a quantitative tool for monitoring cartilage function in diseased or repair cartilage. We examined 32 knees using delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC), 20 years after a complete ACL tear. Only subjects who had coped with the ACL injury without ACL reconstruction (ACLR), and who presented without radiographic signs of osteoarthritis (OA) at an earlier 16-year follow-up, were included in this study.

Delayed contrast-enhanced MRI of cartilage (dGEMRIC) is a noninvasive technique to study cartilage glycosaminoglycan (GAG) content in vivo. This study evaluates dGEMRIC in patients with preradiographic degenerative cartilage changes. Seventeen knees in 15 patients (age 35-70) with arthroscopically verified cartilage changes (softening and fibrillations) in the medial or lateral femoral

Inclusion criteria for these 12 subjects (5 males, age 23–28 years, mean 25 years) were: 1) no his-tory of injury or pain of the knee; 2) no abnormality at physical examination of the knee; 3) no pathologic changes at diagnostic MRI. 18 subjects with knee pain In another study, 15 subjects with unilateral ACL injury were examined using dGEMRIC with the contralateral knee used as control. 12 The median time from injury to MRI was 82 days and the median slice of medial compartment was selected for comparison. 2017-5-26 · “Knee Cartilage Extraction and Bone-Cartilage Interface Analysis from 3D MRI Data Sets”, SPIE, 2004. 2.

dGEMRIC (delayed gadolinium-enhanced MRI of cartilage) 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. Knee joint distraction (KJD) is a less known joint preserving treatment and indicated for both unilateral and generalized knee OA. KJD is performed by placing an external fixation device for 6 weeks, allowing for a renewal of the joint homeostasis, where anabolic activity takes over catabolic activity, providing a more healthy Delayed contrast-enhanced MRI of cartilage (dGEMRIC) is a noninvasive technique to study cartilage glycosaminoglycan (GAG) content in vivo.
