| 中文摘要: |
| 可挽救心肌或心肌挽救指数对急性心肌梗死患者治疗策略选择、疗效评价、预后判断有重要价值。计算可挽救心肌的前提是准确评估心肌危险区和梗死核心。心血管磁共振(CMR)能较准确评估危险区及梗死核心。本文将对CMR常用的扫描技术(T2WI、灌注成像、延迟强化等)及新的扫描技术(T2 mapping、T1 mapping、T1ρ等)评估急性心肌梗死危险区和梗死核心的机制、优势、目前存在问题及研究趋势进行综述。 |
| 英文摘要: |
| The salvageable myocardium (SM) or myocardium salvage index (MSI) in patients with acute myocardial infarction has shown great clinic significance in therapeutic strategies, efficacy evaluation and prognostic assessment. Assessment of SM depends on accurately delineating the area at risk (AAR) and myocardium infarction core (MIC). Cardiovascular magnetic resonance (CMR) is considered to be a preference tool to assess AAR and MIC for its accurate quantification ability. The basic principles, advantages and disadvantages of different kinds of common used and innovative scanning techniques of CMR, including T2WI, T2 mapping, T1 mapping, T1ρ, perfusion imaging and late gadolinium enhancement, in assessment of AAR and MIC were reviewed in this article. |
