A thorough description of perfusion analysis and basic DSC MR acquisition concepts has been described in the companion article to this article, which the interested reader may also find useful. DSC MR imaging requires an MR imaging pulse sequence that is sensitive to magnetic susceptibility changes to register the contrast concentration changes when GBCA passes through the capillary bed. Any pulse sequence that has T∗-weighting can be used to pick up these changes, provided that the sequence is fast enough to acquire an image of that slice of tissue at least every 1 to 2 second.
一篇关于灌注分析和基本 DSC MR 采集概念的详细描述已经在本文的相关文章中给出，有兴趣的读者也可能会发现该文章有用。DSC MR 成像是一种对磁敏感性变化敏感的磁共振成像脉冲序列，用于在 GBCA 通过毛细血管床时记录对比剂浓度变化。任何具有 T∗加权的脉冲序列都可以用于检测这些变化，只要序列足够快，能够至少每 1 到 2 秒采集一次该组织切片的图像。
