cine imaging
Pronunciation: SIN-eh
Dynamic cardiac MRI technique that captures moving images of the heart throughout the cardiac cycle, similar to a movie loop.
Full Definition
Cine imaging is the fundamental dynamic imaging technique in cardiovascular magnetic resonance that acquires multiple phases of the cardiac cycle to create moving images of cardiac function. Using steady-state free precession (SSFP) sequences, cine imaging provides excellent contrast between blood and myocardium, enabling assessment of ventricular function, wall motion, and valve function. Images are typically acquired in standard cardiac planes (short-axis, two-chamber, four-chamber) and displayed as continuous loops. Cine imaging forms the basis for calculating ejection fraction, stroke volume, and cardiac output, and is essential for detecting wall motion abnormalities.
Usage
Usage note: Distinguish from static imaging sequences; specify imaging planes acquired.
