摘要
脑胶质瘤是常见的颅内原发肿瘤,多呈浸润性生长,正确判定肿瘤边界对指导外科手术及确定术后放疗界限具有重要意义。随着磁共振灌注成像技术的不断发展,动脉自旋标记(arterial weighted imaging,ASL)技术无创且能良好评价胶质瘤的微血管密度,而MR动态增强成像能较好地评估胶质瘤的新生血管状态,这两者在肿瘤浸润区的特点也成为近几年研究的热点,作者就脑胶质瘤瘤周浸润的ASL灌注成像及MR动态增强成像的研究进展进行综述。
Glioma is a common intracranial primary tumor. Glioma has invasive growth, and it is important to correctly determine the boundary of the tumor to guide surgery and determine the postoperative radiotherapy boundaries. With the development of magnetic resonance perfusion imaging, ASL can be a noninvasive perfusion MR method for evaluation of the MVD of brain gliomas. Dynamic contrast- enhanced MRI （DCE-MRI） is a useful way to evaluate the angiogenesis of glioma. In recent years, their furthers in the periphery of gliomas have become a hot spot. In this paper, we made a review from the aspects of DCE-MRI and ASL perfusion imaging in the periphery of gliomas.
