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 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. 22 In OA, the highly negatively charged GAG are lost and when intravenously injected, the MRI contrast agent gadolinium dGEMRIC (delayed Gadolinium Enhanced Magnetic Resonance Image of Cartilage) is a well-established technique for cartilage quality assessment in osteoarthritis at clinical field strengths.
Delayed gadolinium‐enhanced MRI of cartilage (dGEMRIC) is a new imaging technique to estimate joint cartilage glycosaminoglycan content by T1‐relaxation time measurements after penetration of the hydrophilic contrast agent Gd‐DTPA2‐.

Magnetic Resonance Imaging (MRI) T2 mapping and delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) are able to detect early degenerative changes. The hypothesis of the study was that cartilage surrounding a focal cartilage lesion in the knee does not possess degenerative changes. 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.

Jonas Svensson. Delayed gadolinium-enhanced MRI of the meniscus (dGEMRIM) in patients with knee osteoarthritis: Relation with meniscal degeneration on conventional MRI, reproducibility, and correlation with dGEMRIC Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is an imaging technique that can identify pre-radiographic degenerative changes in articular cartilage, and potentially also in the meniscus [ 12, 13 ]. When this technique is applied to the latter tissue, it is designated gadolinium enhanced MRI of meniscus (dGEMRIM). Material and methods: Nine patients with knee osteoarthritis (OA), Kellgren-Lawrence grade (KLG) 1-4, were recruited from an ongoing weight loss cohort study. dGEMRIC was performed at 3-T using single (0.1 mmoI/kg) and double (0.2 mmoI/kg) doses of intravenous (i.v.) Gd-DTPA 2-. Contrast-enhanced MRI of human knee cartilage Clinical applications of the novel dGEMRIC technique to study glycosaminoglycan content in articular cartilage Tiderius, Carl Johan L The dGEMRIC index (T1gd) was calculated for each ROI. RMANOVA analysis was used to evaluate improvement in clinical scores and MRI T1gd over time.

Although MRI is not recommended for now to diagnose early knee OA in daily clinical practice, because of lack of validated consensus criteria and the frequent prevalence of structural knee joint changes with MRI, the literature suggests that such MRI-detected lesions may represent early knee OA, and add support for the investigation of intervention effectiveness at the early stage of OA.

double-dose gadolinium contrast in delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) in knee osteoarthritis: is dose reduction possible on 3-T MRI? BackgroundReduction in gadolinium (Gd) contrast agents is wanted due to the uncertainty of the potential side effects.PurposeTo investigate whether it is possible to reduce the contrast dose from c MRI scans may be carried out for a variety of reasons, and will be accordingly targeted at specific zones of the body. Scans of the brain and spinal cord, for instance, not only look for brain and spinal cord injuries but also for signs of MedlinePlus states that an MRI scan can last anywhere between 10 minutes to 2 hours. The test generally lasts for 30 to 60 minutes for most patients. Once MedlinePlus states that an MRI scan can last anywhere between 10 minutes to 2 hours. If you've never had an MRI before, here are some tips to help you get through the procedure. We may earn commission from links on this page, but we only recommend products we back. Why trust us?

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 Methods: Between August 2008 and April 2012, sixty-five patients (seventy-four hips) underwent primary hip arthroscopy with preoperative dGEMRIC and a minimum of two years of follow-up.
