Three-dimensional (3D) neuroimages are generally considered useful for neurosurgical practice. Nevertheless, neuroimaging modalities such as 3D digital subtraction angiography and computerized tomography still insufficient because the resulting images fail to delineate neural structures. Complex procedures mostly performed in cerebrospinal fluid (CSF) space of basal cistern, where vessels structures present along with lesion. The magnetic resonance (MR) imaging-derived constructive interference steady-state (CISS) imaging displays margin between CSF structures, vessels, dura mater detail, a two-dimensional fashion. authors know that volume-rendered CISS would be more surgery than conventional ones. Although usefulness "virtual MR image endoscopy" was reported previously, endoscopic view is different from operative field perspective being emphasized. Therefore, simulate surgical views, made sequence by using an advanced computer workstation. After generating volume images, cutting method used desired plane visualize lesion reference multiplanar reformatted image. call these "real" they comparable field. This newly developed producing real 30 cases contributed understanding relationship surrounding before attempting procedures, minimal invasiveness patient.
