How is cine imaging accomplished

How is cine imaging accomplished, and why is it used?

Cine imaging portrays the heart in motion. Images are acquired during all phases of the cardiac cycle which requires synchronization with the electrocardiogram (ECG) signal. In MRI, this is accomplished with bright blood gradient echo imaging. The most common sequence used for cine imaging is steady state free precession (SSFP), also called balanced fast field echo (FFE), fast imaging employing steady state acquisition (FIESTA), or true fast imaging with steady state precession (FISP) imaging by different MRI vendors. Cine imaging is necessary to evaluate cardiac function and can be used to detect wall motion abnormalities, calculate ejection fraction (where ejection fraction = [(end diastolic volume − end systolic volume) / (end diastolic volume)] × 100%), and study the motion of valve leaflets.
