摘要
脑膜瘤是颅内良性肿瘤中最常见的,CT、磁共振等传统影像学诊断较成熟,但不能很好地区分其良、恶性及不同组织亚型,对于评估预后、判断疗效、预测复发等方面亦有不足。近年来,三维CT血管造影、CT及磁共振灌注成像、磁共振弥散张量成像及波谱成像、正电子发射计算机断层等影像新技术的应用,弥补了这些劣势,进一步满足了临床要求,为制订治疗方案与疗效及预后评估,提供了更多的有效手段;也为脑膜瘤的诊断与治疗提供了更广阔的前景。
Meningioma is the commonest type of benign intracranial tumors. Traditional imaging diagnoses including CT and magnetic resonance imaging are well-established. However,these methods can not satisfyingly distinguish benign or malignant meningiomas and pathological subtypes. In addition,there are still shortcomings in evaluating prognosis,estimating therapeutic response and prognosticating recrudescence. In recent years,the application of new imaging technology such as three dimensional-computed tomographic angiography,CT perfusion,magnetic resonance perfusion,magnetic resonance diffusion tensor imaging,magnetic resonance spectroscopy,and position emission tomography just makes up these deficiencies and satisfies more clinical requirements. These techniques just reflect biologic characteristics of meningioma in vivo and give more help for the design of the operation plan,estimate of the therapeutic response and the prognosticating recrudescence. Furthermore,they also provide bright prospects for diagnosis and therapy of meningioma.
