Comparison of Quantitative T2 Mapping Techniques for Articular Cartilage
Introduction: T2 relaxation time mapping of free water content and mobility in articular cartilage provides an indirect assessment of collagen content and orientation [1]. Biochemical changes are characteristic of the early stages of osteoarthritis (OA), and T2 mapping is increasingly used in both clinical and research settings. New MR pulse sequences, including 3D approaches, provide more adva...
متن کاملImpact of different coils on biochemical T2 and T2* relaxation time mapping of articular cartilage
Introduction: In the evaluation of articular cartilage, cartilage repair and OA, biochemical magnetic resonance imaging (MRI) plays an important role. Different biochemical methods are exploited for their potential use at 1.5 Tesla and 3.0 Tesla in various studies and recently in clinical routine protocols (1). Advances in coil-technology significantly improve their ability for the diagnosis of...
متن کاملComparison of T1rho and T2 Mapping of Knee Articular Cartilage in an Asymptomatic Population
OBJECTIVE To analyze subregional differences in T1rho (T1ρ) and T2 values and their correlation in asymptomatic knee cartilage, and to evaluate angular dependence with magic angles. MATERIALS AND METHODS Six asymptomatic volunteers underwent knee MRI with T1ρ and T2 mapping. T1ρ and T2 values were measured by two radiologists independently, at nine subregions in the medial femoral condyle (MF...

متن کاملSpatial variation of T2 in human articular cartilage.
PURPOSE To determine the spatial variation of in vivo cartilage T2 in young asymptomatic adults. MATERIALS AND METHODS Quantitative T2 maps of seven asymptomatic young male adults and one male volunteer with a history of previous intraarticular chondroid fragments were calculated by using a multiecho, spin-echo magnetic resonance imaging sequence at 3.0 T. The T2 maps were bilinearly interpol...
