目的:研究超高速计算机断层扫描(ultrafast CT,UFCT)与超声心动描记术(UCG)在左心室容积测定中的关系。方法:采用自身对照的方法,分别测量35例患者的左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)及左心室每搏量(LVSV)。结果:UFCT与UCG在测定左心室容积时有明显的相关性,相关系数分别为r LVEDV=0.890P =0.0001,r LVESV=0.936P =0.0001,r LVSV=0.790P =0.003。UFCT对LVEDV、LVESV的测定值较UCG为大,P =0.018、P =0.001。结论:UFCT与UCG对左心室容积的测定具有相当的统一性,但在评价LVEDV、LVESV时,前者测定值较大。在临床实践中,应根据实际情况选择应用。
Objective: To study the relationship between ultrafast CT (UFTC) and echocardiography (UCG) in the determination of left ventricular volume. Methods: Left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular stroke volume (LVSV) were measured in 35 patients by self-control method. Results: UFCT and UCG in the determination of left ventricular volume were significantly correlated, the correlation coefficients were r LVEDV = 0.890 P = 0.0001 , r LVESV = 0.936 P = 0.0001 , r LVSV = 0.790 P = 0.003 . UFCT LVEDV, LVESV measured values greater than UCG, P = 0.018, P = 0.001. Conclusion: UFCT and UCG have a fairly uniform measurement of left ventricular volume, but in the evaluation of LVEDV and LVESV, the former has a large value. In clinical practice, the application should be based on the actual situation.
