چکیده

Introduction The loss of glycosaminoglycans (GAGs) and breakdown of collagen are typical characteristics of early osteoarthritis (OA) (1). T1rho mapping has been shown to be sensitive to changes in cartilage proteoglycan loss (2). Previous studies have demonstrated that cartilage T1rho values are elevated in OA patients compared to corresponding healthy subjects (3, 4). Recent work has reported (5, 6) that T1rho values of the meniscus and the adjacent cartilage varies in healthy subjects and OA patients. The aim of this study was to assess and compare the compartment-wise T1rho values of menisci and cartilage with doubtful (Kellgren-Lawrence (KL) grade 1) to severe (KL4) OA at 3T.

The relationship between T1rho measurements in the meniscus and cartilage in healthy subjects and patients with osteoarthritis

Meniscal damage has been shown to play a central role in the development and progression of osteoarthritis (OA). However, few studies have investigated the interrelationship between cartilage and meniscus using quantitative magnetic resonance imaging (MRI) measurements. The purpose of this study was to investigate the relationship between cartilage and meniscus and to determine which cartilage ...

Assessment of Cartilage T1rho Values in Osteoarthritic Patients with and without Meniscal Tears at 3T

Introduction Prestructural characteristics of early osteoarthritis (OA) are the loss of glycosaminoglycans (GAG) and collagen breakdown (1). T1rho mapping has been shown to be sensitive to changes in cartilage proteoglycan loss (2). Previous studies have demonstrated that the T1rho values are elevated in OA patients when compared with corresponding healthy subjects (3, 4). Recently, it has been...

Comparison of T1rho imaging between spoiled gradient echo (SPGR) and balanced steady state free precession (b-FFE) sequence of knee cartilage at 3T MRI.

PURPOSE To investigate the difference in T1rho profiles of the entire femoral cartilage between SPGR and b-FFE sequences at 3.0T. MATERIALS AND METHODS 20 healthy volunteers were enrolled in this study. T1rho images of each subject were acquired with two types of pulse sequences: SPGR and b-FFE. Femoral cartilage segmentation was performed by two independent raters slice-by-slice using Matlab...

Evaluation of CD98 Expression in Normal and Osteoarthritic Human Articular Chondrocytes

Background: Recent studies have provided evidence that integrins play roles in recognition of mechanical stimuli and its translation into a cellular response. Integrin signaling may be regulated by a number of mechanisms including accessory proteins such as CD98 (4F2 antigen). Objectives: To determine CD98 expression by human articular chondrocytes and its involvement in human articular mechano...

Parallel imaging of knee cartilage at 3 Tesla.

PURPOSE To evaluate the feasibility and reproducibility of quantitative cartilage imaging with parallel imaging at 3T and to determine the impact of the acceleration factor (AF) on morphological and relaxation measurements. MATERIALS AND METHODS An eight-channel phased-array knee coil was employed for conventional and parallel imaging on a 3T scanner. The imaging protocol consisted of a T2-we...
