屏气功能磁共振评价神经胶质瘤患者脑血管反应性的研究

A review of the studies on evaluating the cerebral vascular reactivity of glioma patients by f MRI with breath-holding

脑瘤周围组织可发生神经血管耦合障碍(neurovascular uncoupling,NVU)导致脑血管反应能力(cerebrovascular reactivity,CVR)下降,屏气条件下功能磁共振成像(functional magnetic resonance imaging,f MRI)检测CVR,可克服基础及临床研究中CVR的个体差异,提高结果的准确性。本文就屏气在磁共振脑功能成像中的应用研究现状进行综述。

Neurovascular uncoupling（ NVU） can occur in the tissue surrounding brain tumor,which results in poor cerebrovascular reactivity（ CVR）. The technology of detecting CVR by f MRI with breath holding can reduce group variance and thus increase the accuracy of detection. This paper presents a review of the studies on detecting the CVR of glioma patients by f MRI with breath holding.
