摘　　要：目的通过4D心脏磁共振(4D MR)法和3D心脏磁共振(3D MR)法检测正常人左心室功能的对比,评价4D MR法检测左心室功能的优势。方法采用4D MR法和3D MR法对9例正常志愿者的每搏输出量(SV)进行测量,并与相位对比磁共振法所测结果进行比较。结果 4D MR法、3D MR法测量左心室的收缩末期容积、舒张末期容积、SV无明显差别。4D MR法获取SV花费时间少,受操作者影响小。结论 4D MR法具有准确性和可重复性高、花费时间短、直观等优点,可作为临床心功能检查的主要方法。Aim To evaluate the advantage of 4D cardiac magnetic resonance（ 4D MR） in measuring the left ventricular function,through the comparison of left ventricular function measured by 4D MR and 3D cardiac magnetic resonance（ 3D MR） in healthy volunteers. Methods The stroke volumes（ SV） of 9 normal volunteers were measured by4 D MR method and 3D MR method. The results were compared with those measured by phase contrast magnetic resonance method. Results There were no significant difference in left ventricular end-systolic volumes,end-diastolic volumes,SVs measured by 4D MR method and 3D MR method. SV got by 4D MR method is characterized with lower time-consumption,being less affected by the operator. Conclusion 4D MR method has the advantages of high accuracy,high repeatability,lower time-consumption,intuition and so on,and can be used as one of the main methods of clinical cardiac function examination.
