Objective: To assess functional parameters of left ventricle by using 64-slice multislice computed tomography(MSCT) and to compare the results of MRI, and investigate the accuracy of data obtained from MSCT coronary angiography in the assessment of left ventricular function. Materials and Methods: End diastolic volume(EDV), end systolic volume(ESV), stroke volume(SV), ejection fraction(EF), and myocardial mass(MM) were calculated based on CT data sets from 20 patients scheduled for noninvasive MSCT angiography of the coronary arteries because of suspected coronary artery disease(CAD). The results from MSCT were compared with MRI. Results: There was no significant difference among the measurements for MSCT and MRI of the ventricular function parameters. A strong correlation between MSCT and MRI(r=0.72~0.92) was found for all parameters. However, EDV, ESV, SV and MM were overestimated with MSCT compared to MRI. While EF was underestimated in MSCT. Conclusions: A strong correlation between MSCT and MRI was found for all parameters. ECG-gated MSCT angiography of the heart is noninvasive assessment of the coronary tree, whereas the analysis of left ventricular parameters provides additional information of cardiac function without further radiation exposure.

Objective: To evaluate the early toxicity of anthracycline on heart through observing the main coronary artery, branches and flow reserve(CFR) by transthoracic coronary artery echocardiography. Methods: Sixty-three patients, who had malignant tumor diagnosed by pathology or cytology(lung cancer), were treated with anthracycline randomly. The same dose of anthracycline was used in the same kind of disease. The left ventricle ejection fraction(LVEF), E/A, the electrocardiogram(ECG), CFR and diameter of the main coronary artery and branches were detected in group before treated with drug and after treatment. Results: The LVEF, E/A, CFR before treated with drug were not altered in the group, the same as the diameters of the main coronary artery, the branching and the ECG. After treatment, the second cycle namely appears the CFR value to reduce, is longer along with the treatment cycle, the CFR value is lower. The third cycle appears E/A value to reduce. The fourth cycle appears the LVEF drop and the ECG change. Conclusion: It is effective to monitor the early toxicity effect of anthracycline on heart by transthoracic coronary artery echocardiography.
