Cardiac magnetic resonance parallel imaging at 3.0 Tesla: technical feasibility and advantages.

Purpose: To quantify changes in signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), specific absorption rate (SAR), RF power deposition, and imaging time in cardiac magnetic resonance imaging with and without the application of parallel imaging at 1.5 T and 3.0 T.

A method for preamplifier-decoupling improvement in quadrature phased-array coils.

Purpose: To improve preamplifier decoupling in a quadrature phased-array coil using a new quadrature combiner configuration.

Materials And Methods: A commercial six-element quadrature cervical-thoracic-lumbar (CTL) coil was used on a 1.5 T GE Signa Lx Scanner.
