Banding-free balanced SSFP cardiac cine using frequency modulation and phase cycle redundancy.

ABSTRACT:

Purpose

To develop a method for banding-free balanced SSFP cardiac cine imaging in a single breath-hold.

Methods

A frequency modulation scheme was designed for cardiac applications to eliminate the time normally required for steady-state stabilization between multiple phase-cycled acquisitions. Highly undersampled acquisitions were reconstructed using a model-based reconstruction that exploits redundancy both over time and between phase cycles. Performance of the methods was evaluated using both retrospective and prospective undersampling in scans with and without frequency modulation from four subjects.

Results

The proposed methods enabled balanced SSFP cardiac cine with three effective phase cycles in only 10 heartbeats. Images acquired with frequency modulation and
