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。
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 time signal-intensity curves（TIC） were gradual progression in 20 cases,no or slight progression in 28 cases and rapid progression in 19 cases.Conclusion：The slight progression in the dynamic contrast-enhanced MRI of the glioblastoma contributes to confirm the diagnosis.
