Cardio-vascular magnetic resonance imaging (CMR) can be used to obtain integrated information on both cardiac function and on advanced tissue characteristics. Using contrast-enhanced techniques, highly diagnostic information on tissue viability, inflammatory changes, and on storage diseases can be obtained within a 45-minute examination. The combination of functional information (using steady-state free precession sequences cine techniques), assessment of myocardial edema (using T2-based techniques), of reversible injury (for example in inflammatory diseases; using T1-based techniques), and irreversible injury (for example in infarction and regional fibrosis, using late gadolinium enhancement techniques) allows disease-specific and prognostic information to be obtained in patients with non-ischemic cardiomyopathy. Contrast-enhanced CMR allows the accurate diagnosis of non-ischemic cardiomyopathies, identification of primary and secondary cardiomyopathies, and can be used to guide therapy, thus avoiding the need for invasive measures such as endomyocardial biopsy in many cases.
心血管磁共振成像（CMR）可用于获取有关心脏功能和高级组织特征的综合信息。使用对比增强技术，在45分钟的检查内可获得有关组织活力、炎症变化和贮积病的高度诊断信息。功能信息（使用稳态自由进动序列电影技术）、心肌水肿评估（使用基于T2的技术）、可逆性损伤评估（例如在炎症性疾病中；使用基于T1的技术）和不可逆性损伤评估（例如在梗死和局部纤维化中，使用钆延迟增强技术）相结合，能够为非缺血性心肌病患者提供疾病特异性和预后信息。对比增强CMR可准确诊断非缺血性心肌病，识别原发性和继发性心肌病，并可用于指导治疗，从而在许多情况下避免了诸如心内膜心肌活检等侵入性措施的需要。
