Long-term and short-term reproducibility of T2 relaxation time in human knee cartilage
INTRODUCTION T2 relaxation time of articular cartilage has been reported to reflect the orientation and concentration of collagen fibrils [1-2]. The reproducibility of T2 in human patellar cartilage has been reported to be close to 5% [3]. However, the patellar cartilage is the thickest one in the knee, and the reproducibility in other articular surfaces has not been studied earlier. In this st...

متن کاملMulti-component T2* relaxation of knee cartilage under UTE acquisitions
INTRODUCTION This work reports observations of T2* relaxation in human knee cartilage explants under ultrashort echo time (UTE) acquisitions in vitro. The objective of this study was to determine the number and distribution of T2* components. We hypothesize that the three major constituents of articular cartilage extracellular matrix (water, collagen, and proteoglycan) contribute to the existen...
متن کاملT2 Relaxation Time Mapping of the Cartilage Cap of Osteochondromas
OBJECTIVE Our aim was to evaluate the cartilage cap of osteochondromas using T2 maps and to compare these values to those of normal patellar cartilage, from age and gender matched controls. MATERIALS AND METHODS This study was approved by the Institutional Review Board and request for informed consent was waived. Eleven children (ages 5-17 years) with osteochondromas underwent MR imaging, whi...
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...
