Object The goal in this study was to highlight the potential of currently available imaging techniques for surgical planning of procedures in and around the limbic system. Methods The authors review traditional and newer imaging techniques as applied to neurosurgical planning. Today MR imaging techniques play a preponderant role. The various applications of functional techniques such as diffusion weighted, diffusion tensor, perfusion, and functional MR imaging methods are discussed. Results In addition to the high-resolution studies of anatomy that can be acquired, especially at higher field strengths (≥ 3 T), MR imaging now also offers the possibility of acquiring functional, metabolic, hemodynamic, and molecular information on normal and pathological brain processes. Conclusions The knowledge obtained using the various imaging techniques contributes substantially to understanding the disease processes in a way that drastically improves surgical planning.

Cerebral cavernous malformations (CCMs) are divided into sporadic and familial forms. For clinical imaging, T2-weighted gradient-echo sequences have been shown to be more sensitive than conventional sequences. Recently more advanced imaging techniques such as high-field and susceptibility-weighted MR imaging have been employed for the evaluation of CCMs. Furthermore, diffusion tensor imaging and functional MR imaging have been applied to the preoperative and intraoperative management of these lesions. In this paper, the authors attempt to provide a concise review of the emerging imaging methods used in the clinical diagnosis and treatment of CCMs.

New functional neuroimaging techniques are changing our understanding of the human brain, and there is now convincing evidence to move away from the classic and clinical static concepts of functional topography. In a modern neurocognitive view, functions are thought to be represented in dynamic large-scale networks. The authors review the current (limited) role of functional MR imaging in brain surgery and the possibilities of new functional MR imaging techniques for research and neurosurgical practice. A critique of current clinical gold standard techniques (electrocortical stimulation and the Wada test) is given.

Abstract Context.—Radiologic studies are obtained for diagnostic and treatment planning purposes in the evaluation of patients with intracranial neoplasms. These studies are discussed at radiology/pathology working conferences and are often beneficial in the analysis of pathologic specimens for tissue diagnosis. Therefore, clinical pathologists should be aware of the current and evolving imaging techniques that are used in the radiologic assessment of intracranial neoplasms. Objective.—To describe the imaging techniques used in the assessment of intracranial neoplasms and provide current references. Data Sources.—We searched PubMed for articles published between 1995 and 2006 and also reviewed several textbooks on intracranial neoplasms, to prepare a discussion of basic modalities such as computed tomography (CT) and magnetic resonance (MR) imaging as well as advanced imaging techniques such as CT and MR angiography and venography, CT and MR perfusion, MR spectroscopy, functional MR imaging, and positron emission tomography. Conclusions.—Knowledge of currently used imaging techniques for the assessment of intracranial neoplasms will assist the clinical pathologist in communications with neuroradiologists, surgeons, and referring clinicians. This review will also aid the pathologist in understanding the new and rapidly evolving imaging techniques that will likely become the standard of care in the future.
