摘要

The purpose of this study was to evaluate the role of multi-slice computed tomography (MSCT) in assessing global left ventricular (LV) function.
Twenty patients (16 male, 4 female) with angina were enrolled, the ages ranged from 42 to 78 years. Data from standardized 64-MSCT scan was analyzed with dedicated analysis software to evaluate the global LV function. Conventional angiography was used as the standard for comparison. Statistical analysis with Pearson's correlation was used.
For LV volumes, there was excellent correlation for end-systolic volume (r=0.83, p＜0.001) and moderate correlations for end-diastolic volume (r=0.57, p=0.014). Good correlation was also observed (r=0.73, p＜0.001) in the evaluation of global ejection fraction.
Our result indicates that it is reliable to assess global LV function with 64-MSCT. Functional analysis in additional to anatomical evaluation may increase the clinical efficacy of MSCT.
