Fast Imaging Employing Steady-State Acquisition

**Semantic type:** Diagnostic Procedure

**Definition:** An acquisition sequence that provides images of fluid filled structures with very short acquisition times. It uses the T2 steady state contrast mechanism to provide high signal-to-noise-ratio images with strong signal from fluid tissues while suppressing background tissue for contrast and anatomic detail of small structures.

**Synonyms:** - Balanced Steady-State Gradient Echo - FIESTA
