In-situ Response Measurement of Degenerated Articular Cartilage to the Loading in 3-T MRI
The aim of this study was to assess the changes in MRI parameters during applied load directly in MR scanner and correlate these changes with biomechanical parameters of human articular cartilage. Cartilage explants from patients who underwent total knee replacement were examined in the micro-imaging system in 3-T scanner. Concerning MRI parameters, T1 withoutand T1 with contrast agent as a mar...
متن کاملT(1ρ) MRI in Alzheimer's disease: detection of pathological changes in medial temporal lobe.
BACKGROUND The need of an early and noninvasive diagnosis of AD requires the development of imaging-based techniques. As an alternative, the magnetic resonance image (MRI) relaxation time constant (T1ρ) was measured in brains of Alzheimer's disease (AD), mild-cognitive impairment (MCI), and age-matched controls in order to determine whether T1ρ values correlated with the neurological diagnosis....
متن کاملMRI of articular cartilage at microscopic resolution
This review briefly summarises some of the definitive studies of articular cartilage by microscopic MRI (µMRI) that were conducted with the highest spatial resolutions. The article has four major sections. The first section introduces the cartilage tissue, MRI and µMRI, and the concept of image contrast in MRI. The second section describes the characteristic profiles of three relaxation times (...
متن کاملMRI Assessment of Articular Cartilage Repair
Articular cartilage lesions in the young population predispose to the development of precocious osteoarthritis. Poor healing of cartilage damaged by trauma or degeneration has been ascribed to avascularity. Cartilage lesions are associated with significant morbidity, including lifestyle restrictions, especially in individuals engaged in sports. The past decade has seen the evolution of a number...
متن کاملArticular cartilage and changes in Arthritis: Collagen of articular cartilage
The extracellular framework and two-thirds of the dry mass of adult articular cartilage are polymeric collagen. Type II collagen is the principal molecular component in mammals, but collagens III, VI, IX, X, XI, XII and XIV all contribute to the mature matrix. In developing cartilage, the core fibrillar network is a cross-linked copolymer of collagens II, IX and XI. The functions of collagens I...
