  1. 心梗定位中的困惑:心电图、心脏超声与CMR 翟亚楠 兰大一院放射科

  2. 磁共振并行采集与定位

  3. 傅里叶转换 • 磁共振经过选层梯度与相位编码、频率编码后再经傅里叶转换可以体素定位 • 那么,心电图为什么不可以呢? • 心电图演变太快,不可精确定位! • 超声通过肋间隙,切面受到局限! • MR在活体定位上有绝对优势!

  4. 心电向量探测与定位

  5. 心电图是怎么测量出来的? http://www.bem.fi/book/16/16.htm

  6. I、II、III导联的差异

  7. I、II、III导联与aVF、aVL、aVR

  8. 通俗记忆 前壁 侧壁 下壁 侧壁

  9. 也可以这么记!

  10. 还可以这么记!

  11. 还可这样记!!

  12. aVR对心梗定位无意义

  13. 那么,到底哪里堵了?

  14. 哪里梗了?

  15. 超声:下壁 vs后壁

  16. 混乱的超声命名 某文献 Ischemia of the inferior myocardial wall

  17. 心电图上的后壁(2006) Rev EspCardiol. 2007;60(7):683-689

  20. 后壁不存在,都叫下壁

  21. 牛眼图 http://www.radiologyassistant.nl/en/p4a3ff48cccc37/ischemic-and-non-ischemic-cardiomyopathy.html

  22. 好吧,都叫下壁其实,个人认为CMR有个后壁挺符合活体解剖的好吧,都叫下壁其实,个人认为CMR有个后壁挺符合活体解剖的 肺面后壁 (近基底部) 膈面下壁

  23. 尸体解剖(把心脏拿出来) 基底部 心尖部

  24. 临床上所谓的“后壁”到底在哪儿? • 老概念 新概念

  25. 再回到这个问题上…

  26. 谢谢!请您指正!
