ABSTRACT
To evaluate the regional left ventricular function (LVF) and to establish the reference data of LVF parameters in the normal people with retrospective ECG gating 64-detector row CT, ten time phases in the cardiac cycle were reconstructed. Scanning was performed on 42 normal adult, and short axis images of the left ventricular were acquired. Endo-cardium and epi-cardium were delineated along with function parameters based on the cardiac analysis software. End-systolic thickness (EST) was thicker than end-diastolic thickness (EDT) (P<0.05). EDT and EST increased, but thickness decreased from apical, mid-ventricular to basal segments. Statistically significant difference was noted between mid-ventricular and basal segments (P<0.05). EDT, EST, thickness and motion of anterior, lateral and inferior segments were greater than those of septal segments in the same ventricular slices (P<0.05). 64-detector row CT could depict the regional LVF accurately. The LVF parameters of normal adults might be useful in diagnosing abnormal left ventricular function.
