发布时间：2018-08-27 17:43
【摘要】：动脉自旋标记(Arterial Spin Labeling,ASL)技术作为一种新兴的灌注成像技术,能够在无需对比剂下进行无损成像,其临床应用日趋广泛。本文阐述了多延迟ASL技术的量化原理,然后与正电子发射型计算机断层显像技术(Positron emission computed tomography,PET)和电子计算机断层扫描技术(Computed tomography,CT)进行对比,分析了该技术在实际应用中的优势。最后,总结了多延迟ASL技术的临床研究内容及科研前景,并探讨了其在脑血管等疾病研究中的应用,指出多延迟ASL技术对于脑血管等疾病的预防及治疗具有巨大的潜力。
[Abstract]:As a new perfusion imaging technique, arterial spin labeling (Arterial Spin Labeling,ASL) can be used in nondestructive imaging without contrast agent, and its clinical application is becoming more and more extensive. This paper describes the quantization principle of multi-delay ASL, and compares it with positron emission computed tomography (Positron emission computed tomography,PET) and electronic computed tomography (Computed tomography,CT). The advantages of this technique in practical application are analyzed. Finally, the clinical research content and prospect of multi-delay ASL are summarized, and its application in the study of cerebrovascular diseases is discussed. It is pointed out that multi-delay ASL has great potential for the prevention and treatment of cerebrovascular diseases.
