Comparison of Three-Dimensional Double-Echo Steady-State Sequence with Routine Two-Dimensional Sequence in the Depiction of Knee Cartilage
Introduction: There are some routine two-dimensional sequences, including short tau inversion recovery (STIR), T2-weighted fast-spin echo (T2W-FSE), and proton-density fast spin-echo for diagnosing osteoarthritis and lesions of the knee cartilage. However, these sequences have some disadvantages, such as long scan time, inadequate spatial resolution, and suboptimal tis...
متن کاملInfluence of knee positions on T2, T*2, and dGEMRIC mapping in porcine knee cartilage.
We examined the influence of flexed knee positions on cartilage MR assessments. Sagittal T(2), T*(2), and delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) maps of the femoral cartilage were obtained in eight 6-month-old porcine femorotibial joints in the extended knee position (position A: flexion 0 degrees and femoral shaft in parallel with the amplitude of static field), flexed knee pos...

متن کاملComparison of T1rho and T2 Mapping of Knee Articular Cartilage in an Asymptomatic Population
OBJECTIVE To analyze subregional differences in T1rho (T1ρ) and T2 values and their correlation in asymptomatic knee cartilage, and to evaluate angular dependence with magic angles. MATERIALS AND METHODS Six asymptomatic volunteers underwent knee MRI with T1ρ and T2 mapping. T1ρ and T2 values were measured by two radiologists independently, at nine subregions in the medial femoral condyle (MF...
متن کاملValue of T2-mapping and DWI in the diagnosis of early knee cartilage injury.
OBJECTIVE To study the value of T2-mapping and diffusion weighted imaging (DWI) in the diagnosis of early injury of knee cartilage. METHODS Seventy-two subjects, including healthy group (n=30) and early cartilage injury group (n=42), were tested on MR scans with T2-mapping and DWI. T2 and apparent diffusion coefficient (ADC) values of cartilage were measured after being processed at the works...
