Intraoperative Image Guidance in Neurosurgery: Development, Current Indications, and Future Trends

Figure 5

Presurgical navigational overlay of CT, MRI, and FDG-PET in a patient prepared for a stereotactic biopsy. The CT images showed only minor changes, the T1 weighted contrast-enhanced MRI showed a very small contrast affine region but a large hypermetabolic lesion in the left parietal brain was revealed by PET, helping to define the best biopsy aim and trajectory.
