Measurement of Posterior Tibial Slope Using Magnetic Resonance Imaging
Background: Posterior tibial slope (PTS) is an important factor in the knee joint biomechanics and one of the bone features, which leads to knee joint stability. Posterior tibial slope affects flexion gap, knee joint stability and posterior femoral rollback that are related to wide range of knee motion. During high tibial osteotomy and total knee arthroplasty (TKA) surgery, proper retaining the...
متن کاملMagnetic Resonance Imaging Based Evaluation of Articular Cartilage Degeneration
Introduction: In-vivo magnetic resonance imaging(MRI) can potentially be used to determine structural changes in articular cartilage of the knee. Water, the dominant component in articular cartilage, is present in both free(70%) and bound form. Bound water is present in collagen fibrils comprising 1020% of the cartilage. Studies indicate that T2 – the proton spin-spin relaxation time parameter ...
متن کاملRelaxation times Mapping Using Magnetic Resonance Imaging
Magnetic Resonance Imaging (MRI) techniques have been used to determine the spin-lattice, T1, and the spin-spin, T2, relaxation times in three phantoms with compositions simulating the T1 and T2 values of human tissues. Some methods of analysis were used in order to obtain the relaxation time maps. It has been shown that reliable results can be also obtained by using approximating methods of in...
متن کاملDetection of early cartilage deterioration associated with meniscal tear using T1ρ mapping magnetic resonance imaging
BACKGROUND In patients with degenerative meniscal tears, subclinical cartilage degeneration may be present even if gross morphological changes are not evident. The aim of this study was to detect occult cartilage degeneration using T1ρ MRI mapping in patients with meniscal tears without obvious radiographic osteoarthritis (OA). METHODS A total of 22 subjects with degenerative meniscal tears i...
