多延迟动脉自旋标记技术的量化原理及其临床研究

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。

Quantization Principle and Clinical Research of Multi-delay Arterial Spin Labeling Technique

As a new perfusion imaging technique, the arterial spin labeling (ASL)technique is able to measure perfusion images noninvasively.This paper explains the quantization principle of muiti delay ASL, and then analyzes the advantages in practical application in comparison to positron emission computed tomography (PET) and computed tomography (CT).At last, the clinical research contents and research prospect of multi delay ASL technology are summarized. The application of multi delay ASL technology in the research of cerebrovascular diseases is also discussed. It is pointed out that multi delay ASL technology has great potential for the prevention and treatment of cerebrovascular diseases.
