Hip dGEMRIC in asymptomatic volunteers and patients with early osteoarthritis: the influence of timing after contrast injection. The purpose of this study was to assess if delayed gadolinium MRI of cartilage using postcontrast T1 (T1Gd) is sufficient for evaluating cartilage damage in femoroacetabular impingement without using noncontrast values (T10). T1Gd and ΔR1 (1/T1Gd − 1/T10) that include noncontrast T1 measurements were studied in two grades of osteoarthritis and in a control group of asymptomatic young Am Hüftgelenk führen präarthrotische Zustände wie Instabilität und Impingement zu pathologischen Belastungen des Gelenkknorpels und sind Risikofaktoren für die Entwicklung einer vorzeitigen Arthrose. 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.

The GAG content is estimated by measuring cartilage T1 values in the presence of the contrast agent Gd-DTPA2-(T1 Gd). A previous study on patients with hip dysplasia, a Our cohort included 25 males and 20 females with a mean +/- SD age at surgery of 29 +/- 11 years. Planar dGEMRIC maps were generated from isotropic, sagittal oblique TrueFISP and T1 sequences. A pediatric musculoskeletal radiologist with experience in hip MRI evaluated studies using radially reformatted sequences. 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).

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 Orthopedic Reviews (2011-09-01) . Delayed gadolinium-enhanced magnetic resonance imaging of hip joint cartilage (dGEMRIC): pearls and pitfalls Perifoveal cartilage injury in fovea alta evaluated on dGEMRIC may be an important marker of foveal acetabular impingement in hip dysplasia.

dGEMRIC, or delayed gadolinium-enhanced MRI of cartilage is a technique that can be used quantitatively to assess glycosaminoglycan content of cartilage or 

We included the first 25 hips (23 patients) who had not undergone previous hip surgery and had a complete dGEMRIC scan. This group of patients was identified 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. 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.

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. 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. nonarthrographic hip MRI protocol is outlined in Table 1.6 Comprehensive Interpretation of Hip MRI Bone Morphologic Characteristics MRI is optimized for soft-tissue characterization, and detailed evaluation of cortical bone is limited because of low relative proton density.

Computed tomography (CT)–based 3D bone models of the same hip joint were used as the gold standard for the Nach aktueller Datenlage besteht begründete Hoffnung, dGEMRIC klinisch zur Diagnostik von degenerativen Gelenkschäden sowie zur Verlaufsbeurteilung nach gelenkerhaltenden Therapieverfahren einzusetzen. Should hip dGEMRIC be performed early or late after the contrast injection?

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. MRI was performed with a 3T system wherein the interval between both measurements was 2 weeks. For iv‐dGEMRIC, FDA approved Gd‐DOTA − was injected intravenously 45 min before the MRI scan. 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.

MRI scans may be carried out for a variety of reasons, and will be accordingly targeted at specific zones of the body. Scans of the brain and spinal cord, for instance, not only look for brain and spinal cord injuries but also for signs of MedlinePlus states that an MRI scan can last anywhere between 10 minutes to 2 hours.
