The aim of this study was to evaluate differences in damage patterns assessed using magnetic resonance imaging (MRI) between hips with femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) as well as to correlate MRI findings with delayed Gadolinium enhanced MRI of cartilage (dGEMRIC) and with patient pain.

Compared with three-dimensional (3D) dual-flip-angle acquisition, 3D magnetization-prepared 2 rapid acquisition gradient-echo MRI enabled more accurate T1 mapping of hip cartilage, was less affected by B 1 inhomogeneities, and showed high accuracy against a T1 reference in participants with hip pain.

Our study aimed to determine whether dGEMRIC indices are predictive of two-year patient- reported outcomes and pain scores following hip arthroscopy. Hips of 11 healthy volunteers were examined at 7 T MRI with an 8-channel radiofrequency transmit/receive body coil using multi-echo sequences for T2 and T2* mapping and a dual flip angle gradient-echo sequence before (T1 0) and after intravenous contrast agent administration (T1 Gd; 0.2 mmol/kg Gd-DTPA 2− followed by 0.5 h of walking and 0.5 h of rest) for dGEMRIC. Delayed gadolinium‐enhanced MRI in cartilage (dGEMRIC) is a valid technique to assess cartilage quality in vivo 10 - 17 and has widely been used in clinical studies for the assessment of hip joint cartilage 18 - 30.

Radiographs (top panel), MRI with indirect arthrography (bottom left panel), and dGEMRIC scan (bottom right panel) of hip with mixed impingement. No evidence of joint space narrowing seen on radiograph but a rim fracture is noted. On the morphologic MRI scan, there is labral chondral degeneration. Methods: In this IRB-approved, retrospective, diagnostic study, we identified the first 25 symptomatic hips (23 patients) who underwent a contrast-enhanced MRI at 3T including a 3-D dGEMRIC sequence for intraarticular pathology assessment due to structural hip deformities. Due to its ability to assess the soft tissues and cartilage that are damaged in early OA, magnetic resonance imaging (MRI) has become the preferred diagnostic tool in pre-operative assessment in hip preservation surgery7. OBJECTIVE: The aim of this study was to evaluate differences in damage patterns assessed using magnetic resonance imaging (MRI) between hips with femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) as well as to correlate MRI findings with delayed Gadolinium enhanced MRI of cartilage (dGEMRIC) and with patient pain.

Gd-DTPA provided the best cartilage delineation. dGEMRIC is a clinically applicable MRI method that may improve identification of early subtle cartilage damage and the accuracy of volume measurements of hip joint cartilage. The aim of this study was to evaluate differences in damage patterns assessed using magnetic resonance imaging (MRI) between hips with femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) as well as to correlate MRI findings with delayed Gadolinium enhanced MRI of cartilage (dGEMRIC) and with patient pain.

The radiology laboratory in a clinic or hospital typically contains several machines using different imaging technologies. Most of the technologists who operate the machines work with X-rays in some form. Techs who pe Learn the causes, symptoms, and treatment of hip osteoarthritis Think you may have arthritis? Learn about the four most common warning signs. Information about symptoms, health and lifestyle habits will help determine the type of arthritis There are several treatments available for hip osteoarthritis, ranging from weight loss and exercise to therapeutic injections. People often need to use more than one treatment to get significant pain relief.

Our study aimed to determine whether dGEMRIC indices are predictive of two-year patientreported outcomes and pain scores following hip arthroscopy. Eight asymptomatic volunteers and 10 patients with early hip osteoarthritis (OA) were investigated with hip delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) at 30, 65, 100, and 135 min after A literature search was performed with PubMed, using the terms "cartilage, osteoarthritis, hip joint, MRI, and dGEMRIC", considering all levels of studies. This review revealed that dGEMRIC can be reliably used in the evaluation of early stage cartilage pathology in various hip joint disorders. 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. QUESTION/PURPOSE In this study, our purpose was to determine the correlation between the relaxation values of three cartilage mapping techniques, dGEMRIC, T1ρ, and T2*, in patients with DDH. The dGEMRIC MRI requires an injection of a contrast agent, while the T1-rho MRI does not.

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.

multaneously measure dGEMRIC and T2 values using the identical regions of interest. dGEMRIC and T2 values of the acetabular and femoral cartilage were measured circum-ferentially using anatomic landmarks. After MRI, bone-cartilage samples were taken from the acetabulum and the femur and stained with toluidine blue for assessment of the

If the T1-rho is shown to be as useful as the dGEMRIC method it can then be used to look at cartilage damage in the hip without having to have an injection. For ia‐dGEMRIC, 10–20 mL of a 2 mM solution of Gd‐ DOTA− was injected under fluoroscopic guidance 30 min before the MRI scan. Results Both ia‐ and iv‐dGEMRIC demonstrated the typical T1Gd pattern in hip joint cartilage with increasing values toward the superior regions in acetabular cartilage reflecting the higher glycosaminoglycan Materials and Methods. T1 mapping at 3.0 T was performed in phantoms and in healthy volunteers using 3D MP2RAGE MRI and 3D DFA techniques with B 1 field mapping for flip angle correction. Participants with hip pain prospectively (July 2019–January 2020) underwent indirect MR arthrography (with intravenous administration of 0.2 mmol/kg of gadoterate meglumine), including 3D MP2RAGE MRI. Perifoveal cartilage injury in fovea alta evaluated on dGEMRIC may be an important marker of foveal acetabular impingement in hip dysplasia.

Recommendations for the medical management of osteoarthritis of the hip or knee, Protocol issues for delayed Gd(DTPA)(2-)-enhanced MRI (dGEMRIC) for 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 possible adverse reactions to the imaging procedure. Radiographs (top panel), MRI with indirect arthrography (bottom left panel), and dGEMRIC scan (bottom right panel) of hip with mixed impingement. No evidence of joint space narrowing seen on radiograph but a rim fracture is noted.
