The radiologic modality that most likely provides the imaging information needed in a patient suspected of having a brain tumors is magnetic resonance imaging. A brain tumors can be reliably ruled out, if the standard magnetic resonance examination is performed properly and experts interpret the results as negative for tumor. In this paper we will illustrate morphological aspects of low-grade supratentorial neoplasms, including tumors of neuroepithelial tissue, such as low-grade diffuse fibrillary astrocytomas, and circumscribed astrocytic lesions (pilocytic astrocytoma, pleomorphic xantoastrocytoma and subependymal giant cell astrocytoma). Then the main practical applications of functional imaging in neurosurgery will be also debated.
对于疑似患有脑肿瘤的患者，最有可能提供所需成像信息的放射学检查方式是磁共振成像。如果标准的磁共振检查操作得当且专家将结果解读为无肿瘤迹象，那么脑肿瘤可以被可靠地排除。在本文中，我们将阐述幕上低级别肿瘤的形态学特征，包括神经上皮组织肿瘤，如低级别弥漫性纤维型星形细胞瘤，以及局限性星形细胞病变（毛细胞型星形细胞瘤、多形性黄色星形细胞瘤和室管膜下巨细胞星形细胞瘤）。此外，还将讨论功能成像在神经外科中的主要实际应用。
