In this particular study, the B1 variations are shown to be of minor influence at 1.5T and may thus in some carefully tested applications possibly be neglected. Standardized dGEMRIC maps of the weight-bearing portion of a representative hip articular cartilage, superimposed to GRE coronal images. Values smaller than zero indicate GAG concentration lower The dGEMRIC MR T1 map is reconstructed from images acquired consec- protocol lasted approximately 15 min. utively with different inversion times (TIs). In patients, the dGEMRIC protocol [10] was performed Automated image registration may improve dGEM- twice with an interval of 7 days (range 5–14 days). The dGEMRIC indexof each hip was calculated as the mean T1Gd of its ROI, excluding voxels with T1Gd >1300 ms, according to standard protocol at our institution. dGEMRIC indices were then adjusted for BMI to correct for differ-ences in distribution volume using the formula described by Tide-rius et al.26.

2021-03-19 · Anterior femoroacetabular impingement (FAI) is associated with labral tears and acetabular cartilage damage in athletic and young patients. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is an imaging method for detecting early damage to cartilage. dGEMRIC indices similar to those from their matched controls and in the normal range for hip cartilage. In all but one of the eight subjects the anterior dGEMRIC index was lower than that in the posterior region.

Delayed contrast-enhanced MRI of cartilage 2013-07-01 Background: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a validated technique for evaluating cartilage health in developmental dysplasia of the hip (DDH), which can be a helpful prognosticator for the response to surgical treatments. dGEMRIC requires intravenous injection of gadolinium contrast, however, which adds time, expense, and 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. imaging of cartilage, abbreviated dGEMRIC, can be used to estimate the GAG content of cartilage.

On average, there was a 13% decrease in the dGEMRIC index of the injured knee compared to the uninjured knee. There were no significant effects due to test order (P=0.800) or cartilage location (P=0.439). What does DGEMRIC stand for? List of 7 DGEMRIC definitions. Top DGEMRIC abbreviation meanings updated February 2021 dGEMRIC, like most biochemical methods for measuring cartilage GAG including radiotracer, histology with cationic dyes, and biochemical assays, is based on biophysical principles elucidated by Maroudas almost 40 years ago . These principles rely on the fact that GAG is the source of the majority of the fixed charge on the cartilage Traditionally dGEMRIC has been performed using a two-dimensional T1-weighted inversion recovery (2D-IR) sequence to acquire data for quantitative T1 mapping [18, 19].The major advantage of this method is the widespread availability of the sequence and desirable contrast properties (cartilage versus fluid).

SummaryObjectiveDelayed gadolinium-enhanced MRI of cartilage (dGEMRIC) reflects cartilage glycosaminoglycan (GAG) distribution. The technique assumes that the plasma levels of the contrast agent Gd-DTPA2− are the same across individuals after intravenous (IV) injection, when dosing by weight. To compare several dGEMRIC acquisitions of the same knee measured at different time points, a surface to surface registration algorithm was used to compute the point to point correspondence between dGEMRIC acquisition pairs. The point to point correspondence was then used to generate a 3D delta map of the dGEMRIC data. dGEMRIC Samir Sur, MA,1 Tallal Charles Mamisch, MD,2 Timothy Hughes, PhD,3 and Young-Jo Kim, MD, PhD1* Purpose: To determine the feasibility of using a high reso-lution isotropic three-dimensional (3D) fast T1 mapping sequence for delayed gadolinium-enhanced MRI of carti-lage (dGEMRIC) to assess osteoarthritis in the hip. Standardized dGEMRIC map (left), dGEMRIC map obtained normalizing the corresponding T 1 map by 500 ms (center) and T 1 -weighted image (right), showing for a coronal plane the weight-bearing A recent study indicated that low dGEMRIC may predict future radiographic knee OA.43 The dGEMRIC index has been shown to be low in individuals with moderate to severe radiographic knee OA,15 after cruciate ligament injury44 45 and in diseased knee compartments on arthroscopy.46 In addition, a range of dGEMRIC values has been observed in radiographically comparable compartments demonstrating inium contrast, however, which adds time, expense, and possible adverse reactions to the imaging procedure. Newer MRI cartilage mapping techniques such as T1 rho (ρ) and T2* have been performed in the hip without the need for any contrast, although it is unknown whether they are equivalent to dGEMRIC.
