[Assessment of global left and right ventricular function with 64 multi-detector row computed tomography in healthy adults].
To evaluate the global left and right ventricular function and establish the CT reference data of global ventricular function parameters in normal people, 56 normal subjects (male, 28 cases; female, 28 case) were scanned with retrospective ECG gated 64-detector row CT. Ten time-phases in the cardiac cycle were reconstructed and short-axis images were acquired. On the cardiac analysis software, endo-cardium and epi-cardium of left and right ventricle were delineated and global function parameters were calculated. Left and right ventricular end-diastolic volume (LV/RVEDV), end-systolic volume (LV/RVESV), stroke volume (LV/RVSV), and wall mass (LV/RVWM) were significantly greater (P < 0.05) in men than in women, but cardiac output (LV/RVCO) and ejection fraction (LV/RVEF) exhibited no difference in women and men. In man group and woman group, LVWM was greater than RVWM (P < 0.01). LVESV, RVESV and body mass Index (BMI) were shown to have significant negative-correlation; the correlation coefficient = -0.54 and r = -0.53. LV/RVSV, LV/RVEF and BMI were noted to have significant positive-correlation; the correlation coefficients were 0.87/0.97 and 0.69/0.62, respectively. The normal global left and right ventricular functions differ significantly according to gender and body size.
