Synopsis

Keywords: Myocardium, Cardiovascular

Motivation: The two-dimensional (2D) cine balanced steady-state free precession (SSFP) sequence requires multiple breath-holds for cardiac imaging. A three-dimensional (3D) cine Enhanced sensitivity encoding (SENSE) by Static Outer-volume Subtraction (ESSOS) sequence was introduced to reduce the acquisition time.

Goal(s): To explore the diagnostic value of the 3D cine sequence in patients with hypertrophic cardiomyopathy (HCM).

Approach: All patients with HCM were scanned for cine imaging using conventional 2D SSFP and 3D ESSOS sequences. Cardiac structure and function parameters measured by 3D cine and 2D cine were compared.

Results: The 3D cine can rapidly obtain cardiac parameters with good diagnostic accuracy in patients with HCM.

Impact: The 3D ESSOS cine has good diagnostic accuracy for HCM. This sequence can acquire whole-heart images in a single breath hold, greatly improving efficiency and reducing patient discomfort. It should be used to screen people at high risk for HCM.
