Impact 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 کاملKnee Cartilage Thickness, T1ρ and T2 Relaxation Time Are Related to Articular Cartilage Loading in Healthy Adults
Cartilage is responsive to the loading imposed during cyclic routine activities. However, the local relation between cartilage in terms of thickness distribution and biochemical composition and the local contact pressure during walking has not been established. The objective of this study was to evaluate the relation between cartilage thickness, proteoglycan and collagen concentration in the kn...
متن کاملEffect of Knee Alignment on T2 Relaxation Time of Articular Cartilage
INTRODUCTION Varus and valgus malalignment of the knee increases the risk of medial and lateral osteoarthritis (OA) progression, respectively [1]. T2 relaxation time correlates with collagen content [2] and water content [3] of cartilage, as well as with the integrity [4] and arrangement [5, 6] of the collagen network. It may provide a sensitive tool to detect early degenerative changes in arti...
متن کاملThe Application of Magnetization Transfer Ratios and T2 Relaxation Time to Patellar Articular Cartilage at 3t
Introduction: Magnetic resonance imaging (MRI) has been established as the standard cartilage imaging modality, and techniques have been developed and optimized to visualize cartilage morphology and to analyze its biochemical composition [1]. T2 mapping technique, which assesses the loss of collagen matrix integrity and increase in water content is currently recognized and there are many studie...
