Objective

The purpose of our study was to evaluate intra-operative ultrasound as a means of resection control of brain tumors. Furthermore we looked for tumor species suitable for ultrasound representation.

Methods

Using a Siemens Omnia Sonoline Ultrasound, 40 tumors were examined, high grade gliomas (72%), metastases (18%) and others (10%). We focused on tumor imaging by ultrasound regarding its reliability of tumor expansion and margins. Evaluation of images was done by correlating the intra-operative measured tumor volume before and after resection with pre- and post-operative measured volume by MRI. Corresponding to a deviation of the ultrasound by 10, 20 and more then 20% from the MRI, the correlation was ranked good, moderate and poor.

Results

High grade gliomas mostly showed inaccurate images with a moderate or poor correlation resulting in incomplete resection. Metastases resulted in a good to moderate correlation with satisfactory resection. The other tumors had poor images with larger tumor residues.

Conclusions

The reliability of intra-operative ultrasound depends on tumor kind. It is beneficial to use intra-operative ultrasound for the resection of metastases and few high grade gliomas.
