Brain mapping in Neurosurgical oncology

After the introduction of MRI, new modalities facilitated the procedure of surgical planning to achieve the microsurgical goal and improve prognosis and quality of life in patients. Despite the variable applications of preoperative and intraoperative mapping and monitoring systems, several limitations and concerns are reported for every modality as well. In this issue of the IrJNS, we are delighted to present papers discussing different aspects of brain mapping in neurosurgical oncology, including brain mapping, DTI tractography, and navigation systems. Moreover, new modalities such as fluorescein image-guided surgery (FIGS) are discussed.
