Intraoperative MRT in der Neurochirurgie

Zusammenfassung

Intraoperative Magnetresonanztomografie (iMRT) findet eine zunehmende Anwendung in der Resektion glialer Tumoren des Gehirns. Durch die iMRT ist es möglich, die intraoperativ auftretenden Veränderungen des OP-Situs in der besten Darstellungsmodalität zu erfassen und dem Operateur mithilfe der Neuronavigation situationsgerecht zu präsentieren. Zum Betrieb einer solch komplexen Technik ist ein hoher Grad an fachlicher Kompetenz aller beteiligten OP-Mitarbeiter erforderlich. Durch zunehmende Systemintegration und neue bildgebende Modalitäten der Hochfeldscanner eröffnen sich neue Perspektiven in Bezug auf die Effizienz und das Risikoprofil des chirurgischen Eingriffs. Die Auswertung eigener Daten zeigt eine deutliche Zunahme der vollständigen Tumorresektionen sowohl für die glialen Tumoren als auch für die Hypophysenadenome.

Abstract

The application of intraopeartive magnetic resonance imaging (iMRI) in the resection of glial tumors is experiencing growing acceptance. The iMRI allows the assessment of intraoperative developments with the best available imaging modality and the situation-adapted presentation of this information with the use of neuronavigation. A high degree of professional competence of all OR staff is required to operate such a complex technique. Increasing system integration and new imaging modalities of the high-field scanners open new perspectives on the efficiency and the risk profile of the surgical procedure. The analysis of our own data shows a significant increase in the rate of complete tumor resection for gliomas, as well as the pituitary adenomas.
