Current knowledge and importance of dGEMRIC techniques in diagnosis of hip joint diseases Zilkens, Christoph; Tiderius, Carl Johan LU; Krauspe, Ruediger and Bittersohl, Bernd () In Skeletal Radiology 44 (8). p.1073-1083. Mark; Abstract Accurate assessment of early hip joint cartilage alterations may help optimize patient selection and follow-up of hip joint preservation surgery.

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

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.

Exclusion criteria were previous hip surgery, slipped capital femoral epiphysis, inflammatory arthropathy, Legg-Calve-Perthes disease, and arthritis of >1 Tonnis grade. Patients were classified in two groups on the basis of a dGEMRIC cutoff of 323 msec, which was one standard deviation (SD) below the study cohortmean dGEMRIC index of 426msec. What Is the Correlation Among dGEMRIC, T1p, and T2* Quantitative MRI Cartilage Mapping Techniques in Developmental Hip Dysplasia? Do dGEMRIC and T2 Imaging Correlate With Histologic Cartilage Degeneration in an Experimental Ovine FAI Model? 7 Tesla quantitative hip MRI: T1, T2 and T2* mapping of hip cartilage in healthy volunteers. Application of dGEMRIC to study clinical hip problems has focused on a single summary index describing the entire joint (3). Quantitative MRI (qMRI) assessment of cartilage morphology has been validated in joints with thin cartilage plates (6) but has not been used to describe local acetabular and femoral cartilage morphology.

His doctor sent him to CDI in Springfield, MA for the injection and MRI. with the injection of fluid called contrast right into the joint – usually a hip, shoulder, wrist

Magn Reson. ISO 7206-10:2003/Amd 1, Implants for surgery - Partial and total hip-joint using delayed gadolimium-enhanced MRI of cartilage (dGEMRIC) and T2 mapping.

The dGEMRIC MRI requires an injection of a contrast agent, while the T1-rho MRI does not. 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.

Delayed Gadolinium-Enhanced Magnetic Resonance Imaging (dGEMRIC) of Hip Joint Cartilage: Better Cartilage Delineation after Intra-Articular than Intravenous Gadolinium Injection.

All patients had hip pain at the time when the images were 2015-08-28 2014-03-01 Should hip dGEMRIC be performed early or late after the contrast injection? C. J. Tiderius 1, R. Jessel 2, Y-J. Kim, D. Burstein 1Department of Radiology, Beth Israel Medical Center, Boston, MA, United States, 2Department of Orthopedics, Children's Hospital, Boston, MA, United States Introduction: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a molecular imaging technique that Patterns of cartilage change in FAI patients are more accurate and better visualized in dGEMRIC, suggesting a higher sensitivity compared to standard MRI (17, 18). dGEMRIC has been validated by previous studies, showing that it is able to detect patterns of cartilage changes in patients with and at risk of hip and knee OA (19-22).

Research output: Contribution to journal › Journal article › Research › peer-review dGEMRIC values, and to explore whether baseline dGEMRIC can predict the development of radiographic hip osteoarthritis. Methods: Prospective cohort (SibKids) study with clinical, radiographic, and MRI assessment at baseline and ﬁve-year follow-up (n ¼ 34).

Se hela listan på academic.oup.com 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.
