目的 探讨心脏磁共振(cardiac magnetic resonance imaging,CMR)在可疑心肌疾病的民航飞行员检查中的应用价值. 方法 2012-2016年因心电图异常或心脏超声怀疑心肌疾病的民航飞行员,行CMR检查.采用3.0T磁共振检查系统(Magnetum,Tim Trio),完成标准的心脏功能成像、首过灌注成像(钆喷葡胺,0.15 mmol/kg)及延迟强化成像,并对结果进行分析及诊断. 结果 先后共6例民航飞行员接受CMR检查,均为男性,年龄24～52岁.所有图像质量满足分析及诊断要求.CMR诊断3例患者为肥厚性心肌病,1例患者为高血压病合并左室肥厚,1例患者为左室致密化不全(left ventricular non-compaction,LVNC),1例患者排除潜在心肌疾病.随访所有患者均无临床心血管事件发生;左室致密化不全患者进展为扩张性心肌病合并收缩功能不全. 结论 飞行员群体中可能存在隐匿的心肌疾病,CMR在确定飞行员可疑心肌病诊断上具有重要的价值.“,”Objective To investigate the practical value of cardiac magnetic resonance imaging (CMR) in evaluating the occult myocardial disease in the physical examination for civil aviation pilots.Methods The pilots who diagnosed as suspicious myocardial disease due to the abnormal electrocardiography or echocardiography from 2012-2016 were referred to CMR examination.CMR were performed by a 3.0 Tesla MRI scanner (Magnetum,Tim Trio,Siemens).Scanning protocol consisted with standard cardiac function,first perfusion (Magvist,0.15 mmol/kg),and late gadolinium enhancement.CMR image analysis and diagnosis were done by experienced doctors.Results Six pilots received CMR exams (6 males,age range by 24-52 years).All images quality was good enough for analysis and diagnosis.Finally,3 cases were diagnosed as hypertrophic cardiomyopathy,1 case was hypertensive left ventricular hypertrophy,1 case was left ventricular non-compaction (LVNC) and 1 case was eliminated the possibility of myocardial disease.In follow-up,no clinical cardiovascular events were reported in all patients.Only the case with LVNC deteriorated into dilated cardiomyopathy with reduced systolic function.Conclusions Occult myocardial diseases could occur in pilots.CMR is very valuable in diagnosing and evaluating suspicious myocardial diseases for pilot population.
