Sodium MRI using a density adapted 3D Radial Acquisition

A. Nagel, F. Laun, M. Weber and L. Schad

Proceedings 16th Scientific Meeting, International Society for Magnetic Resonance in Medicine, Toronto,, p.3254

A density adapted 3D Radial sampling scheme (DA-3D-RAD) was implemented. The readout gradients of the DA-3D-RAD are switched constantly up to a k-space radius k0. Beyond this radius the gradientâ??s amplitude is reduced such that the sampling density in all spherical shells is kept constant. The benefits for sodium MRI compared to conventional 3D Radial sampling are demonstrated. In vivo sodium brain and phantom imaging was performed. This technique leads to a higher SNR compared to conventional radial sequences and improved resolution.
