In high-grade glioma surgery, tumor resection is often guided by intraoperative fluorescence imaging. 5-aminolevulinic acid-induced protoporphyrin IX (PpIX) provides fluorescent contrast between normal brain tissue and glioma tissue, thus achieving improved tumor delineation and prolonged patient survival compared with conventional white-light-guided resection. However, commercially available fluorescence imaging systems rely solely on visual assessment of fluorescence patterns by the surgeon, which makes the resection more subjective than necessary...

Of the many imaging technologies, some have the potential to be used in image-guided surgery and therapy (IGS/IGT). This review of relevant papers on IGS/IGT for lung cancer indicates effective localization and IGS/IGT in early endobronchial lesions by fluorescence bronchoscopic technique. Visualization of early peripheral (nodular) tumors at operation can be achieved by a variety of imaging methods and devices which allow identification, localization and provision of intraoperative real-time images. Recent developments employing fluorescence contrasts and near infra-red light have shown encouraging feasibility and outcome in providing reliable methods for the IGS of cancer generally and lung cancer more specifically with provision of real time intraoperative imaging...

Surgery plays an important role in the management of high-grade gliomas (HGG) and imparts significant tumor-free and overall survival advantages. However HGG margins are often invisible, making their gross total resection (GTR) a difficult task. Hence intraoperative technology such as intraoperative fluorescence was a revolutionary discovery. A critical literature review revealed fluorescence improved the GTR of HGG from 36% using standard surgery to 74.5 and 84.4% using aminolevulinic acid (ALA) or fluorescein (FLCN), respectively...

Percutaneous image-guided rupture of lumbar facet synovial cysts can improve clinical outcomes and obviate the need for open surgery. This series describes eleven patients who had successful CT-guided lumbar facet synovial cyst ruptures, 82% of which experienced excellent pain relief at a minimum of one-year follow-up. Of the five patients who failed prior fluoroscopic-guided synovial cyst rupture, 80% had a successful CT-guided rupture and one-year sustained pain relief. These findings reinforce minimally invasive CT-guided treatment as an excellent option to improve patient symptoms and potentially avoid open surgery...
