## Abstract The purpose of this work is to demonstrate the feasibility of __T__~1ρ~‐weighted magnetic resonance imaging (MRI) to quantitatively measure changes in proteoglycan content in cartilage. The __T__~1ρ~ MRI technique was implemented in an in vivo porcine animal model with rapidly induced c

## Abstract Spin‐lattice relaxation in the rotating frame (__T__~1ρ~) dispersion spectroscopy and imaging were used to study normal and enzymatically degraded bovine articular cartilage. Normal specimens demonstrate significant __T__~1ρ~ “dispersion” (∼60 to ∼130 ms) in the 100 Hz to 9 kHz frequenc
## Abstract Proteoglycan (PG) depletion‐induced changes in __T__~1ρ~ (spin‐lattice relaxation in rotating frame) relaxation and dispersion in articular cartilage were studied at 4T. Using a spin‐lock cluster pre‐encoded fast spin echo sequence, __T__~1ρ~ maps of healthy bovine specimens and specime
## Abstract ## Purpose To investigate the compression‐induced changes in the orientational characteristics in T~2~ anisotropy of articular cartilage using microscopic magnetic resonance imaging (μMRI). ## Materials and Methods Six beagle specimens were subjected to various levels of strain (0% t
## Abstract The aim of this study is to develop __T__~1ρ~ as an MR marker of the compositional and functional condition of cartilage. Specifically, we investigate the correlation of changes in cartilage biomechanical and biochemical properties with __T__~1ρ~ relaxation rate in a cytokine‐induced mo
