scan order (i.e., whether the injured or uninjured knee was imaged first) would influence the indices. We hypothesized that the tibial and femoral dGEMRIC indices would be lower in the ACL-injured knees when compared to the uninjured knees, and that the scan order would not affect the dGEMRIC indices. Since the time

BACKGROUND: Three-dimensional (3-D) delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) helps quantify biochemical changes in articular cartilage that correlate with early-stage osteoarthritis. However, dGEMRIC analysis is performed slice by slice, limiting the potential of 3-D data to give an overall impression of cartilage biochemistry.

Per MRI scan several regions-of-interest (ROI) were defined for different locations in the joint. Design: Thirty-one patientswitha focalcartilage lesion underwent a dGEMRIC scanpriortocartilage repair surgery and at 3 and 12 months follow-up. At similar time points clinical improvement was monitored using the Knee injury and Osteoarthritis Outcome Score (KOOS) and Lysholm questionnaires. Per MRI scan 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.

The femoral head cartilage is intact (color code: white —T1 1,200 ms, black —T1 200 ms) We hypothesized that tibial and femoral Delayed Gadolinium-Enhanced MR Imaging of Cartilage (dGEMRIC) indices would be lower in the medial compartment of the ACL-injured knee than in the contralateral, uninjured knee, and that scan order (i.e., whether the injured or the uninjured knee was imaged first) would not affect the indices. 2010-05-01 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).

A PET scan stands for positron emission tomography, according to MedicalNewsToday. It's a piece of equipment used to show activity and functioning in the body at a cellular level using radiation. Here are facts to consider when you're wonde

The surface coil used was built to conform to the animals and was interfaced with a clinical 3 Tesla Siemens Trio MRI. A fat- 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. Se hela listan på academic.oup.com dGEMRIC index of 454 ± 84 msec (p<0.01) at their 6 months-1 year follow-up scan.

The dGEMRIC indices of the median slice of the medial compartment were determined using the MRIMapper software. Index comparisons were made between knee status (ACL-injured vs uninjured), scan order (ACL-injured first vs uninjured first), and cartilage location (tibia vs femur) using a mixed model.

Eleven hips (11 patients) underwent subsequent joint-preserving hip surgery.

A custom apparatus was developed to hold the knee in the same orientation for every scan.

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.

However, dGEMRIC analysis is performed slice by slice, limiting the potential of 3-D data to give an overall impression of cartilage biochemistry. We hypothesized that tibial and femoral Delayed Gadolinium-Enhanced MR Imaging of Cartilage (dGEMRIC) indices would be lower in the medial compartment of the ACL-injured knee than in the contralateral, uninjured knee, and that scan order (i.e., whether the injured or the uninjured knee was imaged first) would not affect the indices. The dGEMRIC experiment was repeated for 10 asymptomatic volunteers three times with an average interval of 5 days between scans. 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.
