Abstract/OtherAbstract:
BACKGROUND:: Precise lesion localization is necessary for neurosurgical procedures not only during the operative approach, but also during the preoperative planning phase. OBJECTIVE:: To evaluate the advantages of three-dimensional brain surface visualization over conventional two-dimensional magnetic resonance images for surgical planning and intraoperative guidance in brain tumor surgery. METHODS:: Preoperative 3D brain surface visualization was performed with neurosurgical planning software in 77 cases (58 gliomas, 7 cavernomas, 6 meningiomas and 6 metastasis). Direct intraoperative navigation on the 3D brain surface was additionally performed in the last 20 cases with a neurosurgical navigation system. For brain surface reconstruction, patient specific anatomy was obtained from MR imaging and brain volume was extracted with skull stripping or watershed algorithms, respectively. 3D visualization was performed by direct volume rendering in both systems. To assess the value of 3D brain surface visualization for topographic lesion localization, a multiple-choice test was developed. To assess accuracy and reliability of 3D brain surface visualization for intraoperative orientation, we topographically correlated superficial vessels and gyral anatomy on 3D brain models with intraoperative images. RESULTS:: The rate of correct lesion localization with 3D was significantly higher (p=0.001, X), while being significantly less time-consuming (p<0.001, X) compared with 2D images. Intraoperatively, visual correlation was found between the 3D images, superficial vessels, and gyral anatomy. CONCLUSION:: The proposed method of 3D brain surface visualization is fast, clinically reliable for preoperative anatomic lesion localization and patient-specific planning, and, together with navigation, improves intraoperative orientation in brain tumor surgery and is relatively independent of brain shift.
