Detailed knowledge of the cerebrovasculature could reduce the rate of this disorder. Morphological scans typically acquired in stereotactic and functional neurosurgery (SFN) by using 1.5-T (or sometimes even 3-T) imaging units poorly depict the vasculature. Advanced angiographic imaging, including 3- and 7-T 3D time-of-flight and susceptibility weighted imaging as well as 320-slice CT angiography, depict the vessels in great detail. However, these acquisitions are not used in SFN clinical practice, and robust methods for their processing are not available yet. Therefore, the authors proposed the use of a detailed 3D stereotactic cerebrovascular atlas to assist in SFN planning and to potentially reduce DBS-induced hemorrhage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A very detailed 3D cerebrovascular atlas of arteries, veins, and dural sinuses was constructed from multiple 3- and 7-T scans. The atlas contained &gt; 900 vessels, each labeled with a name and diameter with the smallest having a 90-\u03bcm diameter. The cortical areas, ventricular system, and subcortical structures were fully segmented and labeled, including the main stereotactic target structures: subthalamic nucleus, ventral intermediate nucleus of the thalamus, and internal globus pallidus. The authors also developed a computer simulator with the embedded atlas that was able to compute the effective electrode trajectory by minimizing penetration of the cerebrovascular system and vital brain structures by a DBS electrode. The simulator provides the neurosurgeon with functions for atlas manipulation, target selection, trajectory planning and editing, 3D display and manipulation, and electrode-brain penetration calculation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This simulation demonstrated that a DBS electrode inserted in the middle frontal gyrus may intersect several arteries and veins including 1) the anteromedial frontal artery of the anterior cerebral artery as well as the prefrontal artery and the precentral sulcus artery of the middle cerebral artery (range of diameters 0.4\u20130.6 mm); and 2) the prefrontal, anterior caudate, and medullary veins (range of diameters 0.1\u20132.3 mm). This work also shows that field strength and pulse sequence have a substantial impact on vessel depiction. The numbers of 3D vascular segments are 215, 363, and 907 for 1.5-, 3-, and 7-T scans, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Inserting devices into the brain during microrecording and stimulation may cause microbleeds not discernible on standard scans. A small change in the location of the DBS electrode can result in a major change for the patient. The described simulation increases the neurosurgeon's awareness of this phenomenon. The simulator enables the neurosurgeon to analyze the spatial relationships between the track and the cerebrovasculature, ventricles, subcortical structures, and cortical areas, which allows the DBS electrode to be placed more effectively, and thus potentially reducing the invasiveness of the stimulation procedure for the patient.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2010.2.jns091528","type":"journal-article","created":{"date-parts":[[2010,3,26]],"date-time":"2010-03-26T09:53:46Z","timestamp":1269597226000},"page":"1234-1241","source":"Crossref","is-referenced-by-count":33,"title":["Simulation and assessment of cerebrovascular damage in deep brain stimulation using a stereotactic atlas of vasculature and structure derived from multiple 3- and 7-tesla scans"],"prefix":"10.3171","volume":"113","author":[{"given":"Wieslaw L.","family":"Nowinski","sequence":"first","affiliation":[{"name":"Biomedical Imaging Lab, Agency for Science, Technology and Research, Singapore;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beng Choon","family":"Chua","sequence":"additional","affiliation":[{"name":"Biomedical Imaging Lab, Agency for Science, Technology and Research, Singapore;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ihar","family":"Volkau","sequence":"additional","affiliation":[{"name":"Biomedical Imaging Lab, Agency for Science, Technology and Research, Singapore;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fiftarina","family":"Puspitasari","sequence":"additional","affiliation":[{"name":"Biomedical Imaging Lab, Agency for Science, Technology and Research, Singapore;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yevgen","family":"Marchenko","sequence":"additional","affiliation":[{"name":"Biomedical Imaging Lab, Agency for Science, Technology and Research, Singapore;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val M.","family":"Runge","sequence":"additional","affiliation":[{"name":"Department of Radiology, Scott & White Hospital and Clinics, Temple, Texas; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael V.","family":"Knopp","sequence":"additional","affiliation":[{"name":"Department of Radiology, The Ohio State University Medical Center, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns091528","series-title":"Surg Neurol","first-page":"577","article-title":"Preparing the ethical future of deep brain stimulation","volume":"72","author":"Bell","year":"2009"},{"key":"b2-jns091528","series-title":"Expert Rev Med Devices","first-page":"895","article-title":"What the future holds for deep brain stimulation","volume":"4","author":"Benabid","year":"2007"},{"key":"b3-jns091528","series-title":"Neurosurgery","first-page":"754","article-title":"Risk factors for hemorrhage during microelectrode-guided deep brain stimulation and the introduction of an improved microelectrode design","volume":"64","author":"Ben-Haim","year":"2009"},{"key":"b4-jns091528","series-title":"Stereotact Funct Neurosurg","first-page":"73","article-title":"Complications of deep brain stimulation surgery","volume":"77","author":"Beric","year":"2001"},{"key":"b5-jns091528","series-title":"Stereotact Funct Neurosurg","first-page":"367","article-title":"Surgical complications of deep brain stimulation.
