| 摘 要： | 目的：探讨胶质母细胞瘤的MRI动态增强表现。方法：搜集67例胶质母细胞瘤患者的临床及影像资料,回顾性分析其磁共振动态增强表现特点。结果：67例胶质母细胞瘤中,单发者63例,多发者4例。MRI动态增强均呈明显不均质强化,其中28例呈花环样强化,15例呈环形强化,11例呈结节状强化,13例呈囊实性强化。时间-信号强度曲线20例（29.9%）呈缓升型,28例（42.0%）呈平台型,19例（28.4%）呈速升型。结论：胶质母细胞瘤的MRI动态增强具有一定的特征性,平台型时间-信号强度曲线有助于明确诊断。

| Abstract: | Objective:To evaluate dynamic contrast-enhanced MR imaging features of glioblastoma.Methods:A retrospective review of 67 patients with glioblastoma was perfomed.The dynamic contrast-enhanced MR images of each case were reviewed.Results:In all of 67 cases,single lesion was found in 63 patients,multiple lesions in 4 patients.All the leisions showed marked heterogeneous enhancement,and appeared in four types of pattems:ring enhancement,circular enhancement,nodular enhancement and solid-cystic enhancement.The t... |
