Brain tumors are histologically heterogeneous. A technique for three-dimensional fusing of computed tomography (CT) or magnetic resonance images (MRI) with positron emission tomography (PET) images is described. This allows the anatomic detail provided by CT or MRI scans to be combined with the information about metabolic activity provided by PET scans. The fused images allowed selection of the most metabolically active portions of tumors. Fusion of CT and MRI images with PET scans has allowed first-pass diagnostic yield by providing the surgeon with a map of anatomical as well as functional (metabolic) detail. We describe a technique to allow routine fusion of MRI, CT, and PET information to help guide the neurosurgeon.
脑肿瘤在组织学上具有异质性。本文描述了一种将计算机断层扫描（CT）或磁共振成像（MRI）与正电子发射断层扫描（PET）图像进行三维融合的技术。这使得CT或MRI扫描提供的解剖细节能够与PET扫描提供的代谢活性信息相结合。融合后的图像能够选择肿瘤中代谢最活跃的部分。CT和MRI图像与PET扫描的融合通过为外科医生提供解剖以及功能（代谢）细节图，实现了首次诊断的成功率。我们描述了一种技术，可实现MRI、CT和PET信息的常规融合，以帮助指导神经外科医生。
