动脉自旋标记成像对早产儿脑损伤的早期诊断及预后评估研究进展

Research progress of arterial spin labeling imaging in early diagnosis and prognosis evaluation of brain injury in premature infants

随着磁共振影像技术的不断发展,动脉自旋标记(arterial spin labeling,ASL)技术能够用于测量及评价脑血流灌注,已被逐步应用于临床实践。ASL技术具有安全、无创的独特优势,适合用于早产儿脑发育和脑损伤的诊断和预后评估,为早期诊断及治疗提供了影像学依据。因此,作者对ASL技术辅助早期诊断早产儿常见脑损伤的临床研究现状及进展进行综述。

With the continuous development of magnetic resonance imaging technology,arterial spin labeling(ASL)technology could be used to measure and evaluate cerebral blood flow perfusion,and has been gradually applied in clinical practice.ASL technology has the unique advantages of safety and non-invasive,which is suitable for the diagnosis and prognosis evaluation of brain development and injury in premature infants,and provides medical imaging basis for early diagnosis and treatment.Therefore,this article reviews the clinical research status and progress of ASL technology in early diagnosis of common brain injury in premature infants.
