This is an open-label positron emission tomography/near infrared (PET/NIRF) study to investigate the imaging navigation performance and evaluation efficacy of dual modality imaging probe 68Ga-BBN-IRDye800CW in glioblastoma (GBM) patients. A single dose of 40μg/111-148 Mega-Becquerel (MBq) and 1.0 mg/ml 68Ga-BBN-IRDye800CW will be injected intravenously before the operation and infraoperative respectively. Visual and semiquantitative method will be used to assess the PET images and real-time margins localization for surgical navigation.
Non-invasive preoperative PET imaging evaluation and real-time fluorescence-guided surgery would be of great help in GBM patients. BBN, with the amino acid sequence of Gln-Trp-Ala-Val-Gly-His-Leu-Met-NH2, has been extensively used for the development of molecular probes for the imaging of gastrin-releasing peptide receptor (GRPR), a member of the G protein-coupled receptor family of bombesin receptors that over-expressed in various types of cancer cells including glioblastoma multiforme. For interests in clinical translation of GRPR targeting dual modality probe, an open label dual modality imaging PET/ NIFR study was designed to investigate the safety and imaging guiding performance of 68Ga-BBN-IRDye800CW in patients with GBM.

Optical imaging techniques used for recording patterns of electrical activity in tissues by monitoring transmembrane potentials via FLUORESCENCE imaging with voltage-sensitive fluorescent dyes.
Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.
Minimally invasive procedures guided with the aid of magnetic resonance imaging to visualize tissue structures.
Endoscopic surgical procedures performed with visualization via video transmission. When real-time video is combined interactively with prior CT scans or MRI images, this is called image-guided surgery (see SURGERY, COMPUTER-ASSISTED).
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
