This work improves the performance of interactive real-time imaging with balanced steady-state free precession.

Experimental studies were performed in five healthy volunteers at 3 T using steady-state free precession sequence.

Theory: The balanced steady-state free precession sequence is inherently sensitive to contrast agent enhancement of the myocardium.

For contrast-enhanced MR imaging, a three-section single-shot saturation recovery gradient-recalled echo sequence with steady-state free precession was used.

Fourteen additional subjects underwent contrast-enhanced coronary MRI with an inversion-recovery steady-state free precession sequence after bolus Gd-BOPTA infusion.

An undersampled balanced steady-state free precession sequence with the same undersampling mask was used to acquire the imaging data.

In conclusion, FSD-prepared balanced steady-state free precession in conjunction with electrocardiography gating and image subtraction provides a promising noncontrast-MRA strategy for the distal lower extremities.

Results: The method was implemented at 1.5 T and 3 T, on cardiac cine and multiframe steady-state free precession sequences.

The balanced steady-state free precession (bSSFP) MR sequence is frequently used in clinics, but is sensitive to off-resonance effects, which can cause banding artifacts.

A method is presented that employs the inherent spectral selectivity of the Steady-State Free Precession (SSFP) pulse sequence to provide a spectral band of suppression.
