“…Neuronavigator-guided surgery could provide an optimal means to combine the experience of the neurosurgeon with 3D MR images to determine the tumor margin, not only increasing the rate of total tumor removals, but also protecting normal brain functions. Many authors have attempted to assess their usefulness [10][11][12][13][14][15] . Neuronavigation provides a real-time link between digitized neuroradiological images and anatomic structures.…”

In order to evaluate the effectiveness of neuronavigator-guided microsurgery and keyhole technique for the resection of gliomas, a total of 60 patients with gliomas were exactly located by using neuronavigator during microsurgery. Forty deep-seated gliomas were resected through a keyhole operative approach. Thirty out of the 60 cases were subjected to photodynamic therapy (PDT) after tumor resection. The therapeutic effectiveness of all the cases was recorded and analyzed. The results showed that glioma was totally resected in 52 cases (86.7%), subtotally in 5 (8.3%), and most partially in 3 (5%). Neurological deficits occurred postoperatively in 4 cases. One patient died of multiple system organ failure 4 days after operation. It was concluded that the application of minimally invasive technique could dramatically decrease surgical complications following resection of glioma, and its combination with PDT could obviously improve the quality of life of patients and prolong the survival time.

We propose critical considerations on the usefulness of CT, MRI, and fMRI imaging fusion for the treatment of skull base lesions evaluating 41 cases (24 meningiomas: six petroclival, seven clinoidal, four olfactory, two in the foramen magnum, two spheno-petro-clival, one in the planum sphenoidale, one in the posterior pyramid and one in the PCA; five acoustic schwannomas, three epidermoids, two pituitary adenomas, two craniopharingiomas, two posterior fossa aneurysms, one trigeminal schwannoma, one dermoid and one juvenile angiofibroma).Data were collected, fused, integrated and reconstructed by a dedicated Stealth-Station system for Neuronavigation. CT images were acquired on axial non-overlapping slices, 1-3 mm thick; MRI images were obtained with a 1.5 T system, same FOv and thickness.During surgery the Mean Fiducially Error measured at 6 cm depth and anatomical distortion due to CSF loss was evaluated.Neuronavigation was possible in all cases and successfully applied in preoperative planning and during surgical procedures.The Mean Fiducially Error at 6 cm was 1.7 mm. CSF loss during surgery produced modifications on planned anatomy in a mean value of 0.6 mm.In all cases, imaging fusion for pre and intra-operative neuronavigation provided great advantages in the choice of the best approach, placing of bone flap, correct definition of tumour boundaries and meningeal implant, relationship with functional areas, early identification and real-time correction of the surgical route with respect of deep normal or distorted anatomic or pathologic structures and their eventual encasement or involvement by the pathologic primary process.Neuronavigation appeared ideal for skull base meningiomas making surgical manoeuvres safer, more effective and less invasive. In skull base lesions, CSF loss appeared not significant due to the fact that posterior fossa structures are strictly connected to each other and to the bone, thus are poorly affected by surgical deliquoration. We propose the possible extension of imaging fusion technique with the aim of optimizing the target in radiotherapy for intracranial tumours.Utilità della tecnica di fusione dell'immagini nel trattamento delle lesioni del basicranio RIASSUNTO -Vengono proposte delle considerazioni critiche sull'utilità della fusione di immagini TC, RM, fRM nel trattamento delle lesioni del basicranio.Sono stati valutati 41 casi di lesioni del basicranio (24 meningiomi: 6 petroclivali, 7 clinoidali, 4 olfattori, 2 del forame 300 è stato utilizzato un sistema dedicato StealthStation da Neuronavigazione per la raccolta, fusione e ricostruzione dati. Le immagini TC sono state acquisite su piani assiali non sovrapposti da 1-3 mm di spessore a Fov 24; le immagini RM sono state ottenute con un apparecchio da 1.5 Tesla con lo stesso spessore e campo di vista. In corso di intervento neurochirurgico sono stati valutati l'Errore Fiduciario Medio misurato a 6 cm di profondità e la distorsione anatomica dovuta alla perdita di CSF.La neuronavigazione è stata possibile in tutti i casi ed ...
