AU - BergomSP - 8851958 VL - 2021 AB -心脏磁共振成像(CMR)被认为是测量心脏功能的金标准。此外，在一次CMR检查中，可以获得关于心脏结构、组织组成和血流的信息。然而，CMR由于扫描时间长、需要多次屏气、使用造影剂和相对较高的成本而未得到充分利用。在这项工作中，我们提出了一种快速、全面、无对比的CMR检查，不需要重复憋气，基于近期成像序列的发展。在CMR检测中，耗时的常规序列已被高级序列所取代。具体来说，传统的2D电影和相位对比(PC)序列分别被优化的3d电影和4d流序列所取代。此外，传统的心肌标记已经被快速菌株编码(SENC)成像所取代。最后，在建议的检查中包括T1和T2标测序列，这允许心肌组织的特征。这种快速检测方法已经在体内进行了测试。 The proposed exam reduced the scan time from >1 hour with conventional sequences to <20 minutes. Corresponding cardiovascular measurements from the proposed rapid CMR exam showed good agreement with those from conventional sequences and showed that they can differentiate between healthy volunteers and patients. Compared to 2D cine imaging that requires 12-16 separate breath-holds, the implemented 3D-cine sequence allows for whole heart coverage in 1-2 breath-holds. The 4D-flow sequence allows for whole-chest coverage in less than 10 minutes. Finally, SENC imaging reduces scan time to only one slice per heartbeat. In conclusion, the proposed rapid, contrast-free, and comprehensive cardiovascular exam does not require repeated breath-holds or to be supervised by a cardiac imager. These improvements make it tolerable by patients and would help improve cost effectiveness of CMR and increase its adoption in clinical practice.
