Thirty-five patients with different lesions underwent surgery in which the prototype of a 3D-navigated ultrasonography system was used. A prospective comparative study of both intraoperative imaging modalities was initiated with the first seven cases presented here.<\/jats:p>\n                    <jats:p>In 35 patients (70%) in whom ultrasonography was performed, accurate tumor delineation was demonstrated prior to tumor resection. In the remaining 30% comparison of preoperative MR imaging data and ultrasonography data allowed sufficient anatomical localization to be achieved. Detection of metastases and high-grade gliomas and intra-operative delineation of tumor remnants were comparable between both imaging modalities. In one case of a low-grade glioma better visibility was achieved with ultrasonography. However, intraoperative findings after resection were still difficult to interpret with ultrasonography alone most likely due to the beginning of a learning curve.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Based on these preliminary results, intraoperative MR imaging remains superior to intraoperative ultrasonography in terms of resection control in glioma surgery. Nevertheless, the different features (different planes of slices, any-plane slicing, and creation of a 3D volume and matching of images) of this new ultrasonography system make this tool a very attractive alternative. The intended study of both imaging modalities will hopefully allow a comparison regarding sensitivity and specificity of intraoperative tumor remnant detection, as well as cost effectiveness.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/foc.2001.10.2.4","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T06:53:48Z","timestamp":1201157628000},"page":"1-5","source":"Crossref","is-referenced-by-count":66,"title":["Comparison of intraoperative MR imaging and 3D-navigated ultrasonography in the detection and resection control of lesions"],"prefix":"10.3171","volume":"10","author":[{"given":"Volker M.","family":"Tronnier","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo M.","family":"Bonsanto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Staubert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Knauth","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan","family":"Kunze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian R.","family":"Wirtz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199401000-00008"},{"key":"p_2","first-page":"229","author":"Albert FK","year":"1998","journal-title":"Heidelberg: Springer-Verlag"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199602000-00007"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1007\/BF01842825"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199903000-00016"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19940915)74:6<1784::AID-CNCR2820740622>3.0.CO;2-D"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199710000-00013"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1007\/BF00172602"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199602000-00006"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1982.57.2.0157"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-200012000-00021"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1996.84.5.0737"},{"key":"p_13","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199709000-00020"},{"key":"p_14","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1052008"},{"key":"p_16","first-page":"1642","volume":"20","author":"Knauth M","year":"1999","journal-title":"AJNR"},{"key":"p_17","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1993.79.1.0036"},{"key":"p_18","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199711000-00004"},{"key":"p_20","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199810000-00005"},{"key":"p_21","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1999.91.5.0804"},{"key":"p_22","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199705000-00001"},{"key":"p_23","first-page":"211","author":"Tronnier V","year":"1999","journal-title":"Brain Tumors of Maldevelopmental Origin.
