摘要： 目的 探讨不同心血管影像技术对于糖尿病心肌病患者心室容积及心功能的检测效能。
方法 收集我院诊断为糖尿病心肌病的患者120例，分别使用超声心动图、心脏CT成像(cardiac computed tomography,CCT)以及心脏磁共振(cardiac magnetic resonance,CMR)对患者进行检测，分别测量患者的左心室和右心室舒张末期容积（end diastolic volume,EDV）和收缩末期容积（end systolic volume,ESV），每搏输出量（stroke volume,SV）和射血分数（ejection fractions,EF）。通过统计学分析检测3种检测手段所得结果的差别。
结果 通过对比患者心功能参数发现，超声心动图检测的DCM患者的心室容积在左心室差异无统计学意义，但右心室的ESV要显著小于CMR的检测结果(P＜0.05)。针对所有患者，超声心动图检测的EF要普遍高于CMR的检测结果(P＜0.05)。当患者EF＞50%时，超声心动图的检测结果与CMR的检测结果无明显差异，而患者EF＜50%时，超声心动图的检测结果要显著高于CMR的检测结果(P＜0.05)。CCT和CMR在检测DCM患者心室容积和心功能中展现了很好的一致性；当EF＜35%时，CCT的检测结果明显高于CMR(P＜0.05)。3种检测手段在观察者间和观察者内均表现出较好的一致性。
结论 超声心动图、心脏CT成像以及心脏磁共振对于患者心功能检测结果存在一定差异，临床医生在应用时应根据实际情况综合使用。

Abstract: Objective To investigate the effectiveness of different cardiovascular imaging techniques in detecting ventricular volume and cardiac function in patients with diabetic cardiomyopathy(DCM). 
Methods A total of 120 patients with DCM diagnosed in our hospital were collected. Echocardiography, cardiac computed tomography(CCT) and cardiac magnetic resonance(CMR) were used to detect the left and right ventricular end diastolic volume(EDV), end systolic volume(ESV), stroke volume(SV) and ejection fraction(EF). Statistical analysis was used to detect the difference of the results of the three detection methods. 
Results After comparing the patient′s cardiac function parameters, there was no significant difference in the left ventricular volume of DCM patients detected by echocardiography, but the ESV of the right ventricle was significantly smaller than that of CMR(P＜0.05). For all of the patients, the EF detected by echocardiography was generally higher than that of CMR(P＜0.05). When EF＞50%, there was no significant difference between the results of echocardiography and CMR, but when EF＜50%, the results of echocardiography were significantly higher than those of CMR(P＜0.05). CCT and CMR showed good consistency in the detection of ventricular volume and cardiac function in patients with DCM; When EF＜35%, the detection result of CCT was significantly higher than that of CMR(P＜0.05). The three methods showed good consistency between and within observers. 
Conclusion Echocardiography, CCT imaging and CMR have certain differences in the detection results of patients′ cardiac function, which, therefore, should be used by clinicians according to the actual situation.
