cine MRI
Pronunciation: SINE-ee em-ar-eye
Dynamic MRI technique capturing multiple phases of the cardiac cycle to assess heart function and wall motion.
Full Definition
Cine MRI is a dynamic cardiac magnetic resonance imaging technique that acquires multiple images throughout the cardiac cycle, creating a movie-like display of heart motion. This technique uses ECG gating to synchronize image acquisition with the heartbeat, typically generating 20-30 phases per cardiac cycle. Cine MRI is the gold standard for assessing ventricular volumes, ejection fraction, and regional wall motion due to its excellent spatial and temporal resolution. Steady-state free precession (SSFP) sequences like FIESTA or TrueFISP are commonly used, providing bright blood images with excellent contrast between blood pool and myocardium.
Usage
Usage note: Pronounced 'SINE-ee' not 'sin-eh'; often used interchangeably with 'cine CMR' in cardiac contexts.
