... patient to and from the CT unit can be time-consuming and cumbersome. Here, we report the first 50 patients who underwent stereotactic biopsies using the mobile AIRO® intraoperative CT (iCT) scanner. Methods: A conventional stereotactic frame was mounted to the AIRO® carbon table via carbon adapter. 0...

... made publicly available. Results: The new methods were quantitatively validated through a phantom study and applied successfully to mitigate biopsy uncertainty in a clinical study of meningiomas. Conclusions: The proposed methods improve upon the current state of the art in neuronavigation through...

...Jörgen Boëthius; Gustaf Bergstrand; V. Peter Collins; Göran Edner; Bernhard Tribukait The study concerns the relation between the computerized tomogram, histopathology and DNA distribution in gliomas. The investigation was performed on stereotactic biopsies, which enabled the comparison to be made...

...F. Mundinger; Ch.B. Ostertag; W. Birg; K. Weigel Integrating CT imaging techniques into stereotactic procedures makes it easy to puncture cysts, take biopsies from neoplastic and nonneoplastic lesions, and place radioactive material in tumors at exact and reproducible sites. A stereotactic program...

...Georg Norén; V. Peter Collins 5 cases of tumors of the cerebellopontine angle were subjected to stereotactic puncture and biopsy for various reasons (preoperative differential diagnostic difficulties, cyst evacuation, evaluation of the effect of stereotactic radiosurgery).

Potentially, localization information presently available from CT and MR scans might...

...Timothy C. Ryken; Patric W. Hitchon; Robert M. Roach; Vincent C. Traynelis A review of the stereotactic cases performed at the University of Iowa between February, 1985, and December, 1990, yielded 12 infratentorial stereotactic biopsies in 11 patients. A definitive diagnosis was obtained in 9...
