Objective: Under the surgical macroscopic view, low-grade glioma is frequently difficult to distinguish from healthy brain parenchyma. In this study, preoperative MRIs and intraoperative CTs after tumour resection were merged for resection control.

Method: Eleven patients showing radiological signs of low-grade glioma in MRI imaging were scheduled for tumour surgery. Surgical procedures were always guided by MRI-neuronavigation technique. After biopsy (n=7) or resection (n=4), CT-scans of the still sleeping patients were performed in the operating room. Preoperative MRIs (T2 or T2-FLAIR) and intraoperative CTs were merged and superimposed.

Results: In all patients, very accurate and congruent image fusion was possible. Superimpositions of intraoperative CTs with preoperative MRIs could prove the biopsies (n=7) being precisely located in the tumour formation. In tumour resection (n=4), image fusion showed complete removal of the pathological tissue in all cases.

Conclusions: The fusion of preoperative MRI and intraoperative CT is an accurate and reliable technique to confirm correct localization of executed tumour biopsy or resection.
