eloquent cortex near brain tumors. 11, 20, 24 Functional MR imaging allows for the identification of important functional areas of the cerebral cortex that may be invaded by a neoplasm. This imaging modality focuses on cortical structures but does not provide information about subcortical gray matter and white matter, which in many instances may be involved in invasive, intrinsic brain tumors. Recently, DT imaging has been used to map white matter tracts in the brain. 13, 22, 23 Diffusion-tensor imaging measures the diffusion displacement properties of water in a

). Yet substantial motor and sensory recovery was possible. These observations imply that small stepwise treatments can be expected to produce large gains in function. Development and application of novel methods for determining persistent connections across the lesion in individuals with ASIA Grade A injuries will be important. Such techniques could include diffusion tensor imaging, functional MR imaging, and motor/sensory evoked potentials. The MR imaging analysis of the lesion indicated residual sparing of approximately 25 mm 2 of tissue in an outer donutlike rim

approaches, resection strategies, and treatment options. At this point, MS imaging should be considered as an aid or adjunct to intraoperative electrophysiological measurements. In addition, in the present group of patients with tumors, the intraoperative subcortical mapping of motor pathways often led to restricting the extent of resection ( Fig. 2 ); thus, we see the next complementary step in preoperative functional imaging as the incorporation of diffusion tensor images, or another method of assessing white matter fibers, into a patient's volume data set to define

for careful intraoperative mapping in regions of cerebral eloquence.” Data from our present study demonstrate further proof of this point of view, and we assert that the use of intraoperative cortical and subcortical stimulations (complementing preoperative neurofunctional mapping) represents a valuable adjunct to avoid the occurrence of a definitive postoperative deficit. Nonetheless, there are other recent developments in MR imaging that can help delineate deep white matter tracts, specifically diffusion-tensor imaging. A comparison between this new method and
