近年来,心血管疾病已成为世界范围内导致人类死亡最主要的原因之一.如何做出准确的诊断,并制定有效的治疗方案,从而降低疾病的死亡率成为放射科医生和临床医生日常工作中一个具有挑战性的课题。在心电图和血清心肌酶阳性的情况下,急性心肌梗塞的患者是可以获得紧急且有效的治疗.然而,部分慢性心肌梗塞的患者却不能获得任何治疗,因为慢性心肌梗塞的患者没有典型的临床症状,心电图检测不敏感,血清心肌酶受限.所以,这样的患者常常因为缺乏慢性心肌梗塞的诊断最终导致心血管死亡.因此,准确的诊断和进一步的影像学评估对于治疗和预后进程具有积极的意义.近年来,作为一种新的MRI对比增强技术DE-MRI被越来越多的人认为对诊断慢性心肌梗死是非常有帮助的检查方法.对DE-MRI的成像原理、在慢性心肌梗塞中临床应用及其优点与极限性作一综述.
In recent years, cardiovascular disease has become one of the leading causes of human death in the world and how to make accurate diagnosis and formulate effective treatment programs to reduce the mortality rate has become a daily work of radiologists and clinicians In a challenging topic. Patients with acute myocardial infarction receive an emergency and effective treatment with electrocardiogram and serum cardiinase-positive, however, some patients with chronic myocardial infarction do not receive any treatment because patients with chronic MI do not have typical clinical symptoms , ECG test insensitivity, and serum myocardial enzyme restriction.Thus, such patients often end up with cardiovascular death due to the absence of a diagnosis of chronic myocardial infarction.So accurate diagnosis and further imaging assessment are positive for the treatment and prognostic progress In recent years, as a new MRI contrast enhancement technology, DE-MRI is considered by more and more people as a very helpful method to diagnose chronic myocardial infarction.For the imaging principle of DE-MRI, In clinical application and its advantages and limitations made a review.
