The aim of this article was to analyze the technical and methodological issues resulting from the use of functional magnetic resonance image (fMRI) data in a frameless stereotactic device for brain tumor or pain surgery (chronic motor cortex stimulation). ⋯ In brain tumor surgery, fMRI data are helpful in surgical planning and guiding intraoperative brain mapping. The registration of fMRI data in anatomic slices or in the frameless stereotactic neuronavigational device, however, remained a potential source of functional mislocalization. Electrode placement for chronic motor cortex stimulation is a good indication to use fMRI data registered in a neuronavigational system and could replace somatosensory evoked potentials in detection of the central sulcus.

ReviewOptimizing brain tumor resection. Midfield interventional MR imaging.
The development of the intraoperative MR imager represents an important example of creative vision and interdisciplinary teamwork. The result is a remarkable tool for neurosurgical applications. MRT allows surgical manipulation under direct visualization of the intracranial contents through the eye of the surgeon and through the volumetric images of the MR imaging system. ⋯ Those limits are much tighter around the domain of tool manipulation, where the surgeon will yield, early on, to the enhanced performance of robotics and other technical adjuncts. The era of large open magnet imaging systems for surgical procedures then will come to a close; however, the grander era of the surgeon's integration of precision-guided, multimodality therapeutics will just be beginning. The future will be very bright, indeed.

The role of imaging in diagnosis and therapy has been accepted by physicians. This favorable reception of minimally invasive procedures resulted in the recognition of the feasibility of image-guided approaches. ⋯ The current trend is the evolution of integrated therapy delivery systems in which advanced imaging modalities are closely linked with high performance computing. Obviously, the operating room of the future will accommodate various instruments, tools and devices, which are attached to the imaging systems and controlled by image-based feedback.

[The French Journal of Stomatology and Maxillofacial Surgery: what is the future?].
A scientific journal reflects the dynamics of a specialty and should allow wide diffusion of clinical as well as fundamental research findings in order for all practitioners to keep up with changes in their specialty. These objectives are totally different from a journal designed to meet teaching objectives where general reviews, technical notes or clinical cases are in the forefront. The purpose of this work was to determine the current role of the Revue de Stomatologie et de Chirurgie Maxillo-faciale in an attempt to determine future perspectives. ⋯ Considering that the substance of a scientific review lies in the abundance of its original articles, whether the work reports fundamental or clinical research, but more particularly clinical research for a surgery review, one is obliged to observe that the volume of French publications produced annually is insufficient to fullfil the objectives of a truly scientific journal. The 45% submission rate of case reports is in line with this observation. The number of international publications clearly does not explain this situation since globally, over a 2.5 year period, the number of original articles published was to order of one-third of the number published in the Revue de Stomatologie et de Chirurgie Maxillo-Faciale in the single year of 1999, and since the teams involved were the same.
