Intraoperative Imaging (Acta Neurochirurgica Supplementum, by M. Necmettin Pamir, Volker Seifert, Talat Kiris

Show description

4 patients were surgically treated for lesional or non-lesional epilepsy. The preliminary result of our ongoing workflow-analysis suggests a safe and efficient setup. The suite has been integrated into routine and runs on a daily basis. 5 T significantly reduces imaging time, increases anatomical resolution and provides imaging quality up to a standard that equals state of the art routine diagnostic imaging. Meanwhile ioMRI has entered a stage, where imaging objectives are far beyond the assessment of anatomy, pathology and extent of tumor resection.

5 cm and residual tumor, that was located by intraoperative navigation and resected completely other. This is the space for the positioning of the head. The field-of-view is 20Â16 cm. The magnets are affixed to a U-shaped arm. The arm itself is mounted on a transportable gantry positioned below the operating table. For scanning the magnets are raised, by the system computer under tight manual control, so that the area to be imaged is well centered between the magnet poles. After scanning, the magnets are retracted under the OR table providing good access to the head during surgery.
