Effects of ventricular insertion sites on rotational motion of left ventricular segments studied by cardiac MR.
OBJECTIVE: Obtaining new details for rotational motion of left ventricular (LV) segments using velocity encoding cardiac MR and correlating the regional motion patterns to LV insertion sites. METHODS: Cardiac MR examinations were performed on 14 healthy volunteers aged between 19 and 26 years. Peak rotational velocities and circumferential velocity curves were obtained for 16 ventricular segments. RESULTS: Reduced peak clockwise velocities of anteroseptal segments (i.e. Segments 2 and 8) and ...Expand abstract
