Summary
Brief summary (as posted)
Low grade glioma (LGG) is a slowly evolving, highly invasive intrinsic brain tumor displaying only subtle tissue differences with the normal surrounding brain, hampering the attempts to visually discriminate tumor from normal brain, especially at the border interface. This makes anatomical borders hard to define during early maximal resection, which is the initial treatment strategy. Therefore, innovative, robust and easy-to-use real-time strategies for intra-operative detection and discrimination of (residual) LGG tumor tissue would strongly influence on-site, surgical decision making, enabling a maximal extent of resection. To validate this approach hyperspectral imaging (HSI) - using a SnapScan HSI-Camera (IMEC), stably mounted on an OPMI Pentero 900 microscope (Zeiss) - will be used to generate spectral imaging data patterns that discriminate in vivo low grade glioma tissue from normal brain both on the cortical and subcortical level.

- Hyperspectral Imaging with Snapscan camera
- description
- Included patients will undergo a resection of the low grade glioma as standard-of-care. Hyperspectral imaging data will be acquired by the SnapScan HSI camera mounted on the (standard) surgical microscope. As such, the surgical procedure does not deviate from the common, standard-of-care surgical procedures, apart from the acquisition of intraoperative scanning images using the SnapScan HSI camera on the microscope. The objective of this all is to get an initial high quality in vivo dataset to start exploring the potential of the technology.

- description
- Assessment of discriminate power of HSI data between 468 and 780 nm between tumor and normal brain tissue by comparison of data acquired on imec VNIR HSI Snapscan camera and gold standard image segmentation of brain tissue. Image segmentation of white light images acquired on the Pentero 900 surgical microscope will be performed based on the assessment of the surgeon and on histopathological assessment of biopsies taken within the standard of care procedure. A co-registration of the segmented images and will be transferred to subsequently acquired HSI data and used to statistical assess whether HSI data can be used to discriminate the spectral signatures of healthy and tumorous tissue in vivo.
