RECRUITINGExtent of resection
Volumetric assessment of residual T1 contrast enhancement or FLAIR signal changes in enhancing and non-enhancing glioma, respectively.
Time frame: 48 hours after surgery
image quality
ultrasound image quality, both for 2D and 3D as rated by surgeon and scored from 1(best) to 6 (worst).
Time frame: during surgery
neurological outcome
both at discharge and at 3 months follow up using NIHSS Score
Time frame: both after surgery and at 3 months
Accuracy of device
ultrasound image acuracy compared to preoperative MRI, both for 2D and 3D as rated by surgeon and scored from 1(best) to 6 (worst), including rating of brainshift and navigation inaccuracy.
Time frame: during surgery
