Advanced Quantitative Imaging of Knee Joint Repair: Regatte, Ravinder R.: delayed gadolinium enhanced MRI of cartilage (dGEMRIC), gagCEST and sodium

Purpose. measures relative proteoglycan content of articular cartilage. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage or dGEMRIC measures the fixed-charge density and relative proteoglycan content of articular cartilage using the spin-lattice relaxation time or T1 relaxation time. Current research is investigating the clinical application of dGEMRIC as a quantitative tool for monitoring cartilage function in diseased or repair cartilage.

Also regression analysis was performed to show the influence of local repair on cartilage quality at distant locations in the knee. 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. 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 outcomes were bone mineral mass and strength, and the biochemical composition of knee cartilage as assessed by quantitative MRI measures: dGEMRIC and T2 relaxation time.

What is a knee MRI? An MRI test uses magnets and radio waves to capture images ins therapeutic injections. People often need to use more than one treatment to get significant pain relief.

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. At a time point after an intravenous or intra-articular negatively charged gadolinium agent is injected that allows diffusion of the material to the cartilage, the technique enhances areas of high

Magnetic Resonance in Medicine. 2003;49(3):488-492. OBJECTIVE To assess knee cartilage quality and subjective knee function, 20 years after injury in anterior cruciate ligament (ACL) injured copers. METHOD We examined 32 knees using delayed gadolinium-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC), 20 years after a complete ACL tear. The majority of dGEMRIC studies have been in the knee and hip, although there are a number of reports of dGEMRIC applied to the finger joints [12, 50–52] and ankle . 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.

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.

Longitudinal assessment of femoral knee cartilage quality using contrast enhanced MRI (dGEMRIC) in patients with anterior cruciate ligament injury – comparison with asymptomatic volunteers. Osteoarthritis Cartilage. 2011; 19 : 977-983 Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) in In conclusion, automated registration of dGEMRIC in knee early knee osteoarthritis. Magnetic resonance in medicine 49:488–492 cartilage improves the quality of T1 maps and provides a good 12. 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).
