In vivo sodium imaging of human patellar cartilage with a 3D cones sequence at 3 T and 7 T

3 ? 1.3 ? 4.0 mm3) and a high resolution (1.0 ? 1.0 ? 2.0 mm3). We measured the SNR of the images and the T*2 of cartilage at both 3 T and 7 T. Results: The average normalized SNR values of standard-resolution images were 27.1 and 11.3 at 7 T and 3 T.

Impact of motion on T1 mapping acquired with inversion recovery fast spin echo and rapid spoiled gradient recalled-echo pulse sequences for delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) in volunteers

Purpose: To evaluate the impact of motion on T1 values acquired by using either inversion-recovery fast spin echo (IR-FSE) or three-dimensional (3D) spoiled gradient recalled-echo (SPGR) sequences for delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) in volunteers.

Influence of knee positions on T2, T*2, and dGEMRIC mapping in porcine knee cartilage

Comparison of the MR parameters between positions A and C showed isolated influence of the magic-angle effect, and comparison between positions A and B showed effects of knee flexion.

On the measurement of multi-component T2 relaxation in cartilage by MR spectroscopy and imaging

The multicomponent T2 relaxation in bovine nasal cartilage (BNC) was investigated by nuclear magnetic resonance spectroscopy using the Carr-Purcell-Meiboom-Gill (CPMG) sequence and microscopic magnetic resonance imaging (?MRI) method using a CPMG-SE imaging sequence.

Rapid isotropic 3D-sodium MRI of the knee joint in vivo at 7T

Purpose To demonstrate the feasibility of acquiring high-resolution, isotropic 3D-sodium magnetic resonance (MR) images of the whole knee joint in vivo at ultrahigh field strength (7.0T) via a 3D-radial acquisition with ultrashort echo times and clinically acceptable acquisition times.
