Abstract
UV-excitation with 308 nm was applied clinically to normal and diseased tissues from the urinary bladder, the brain and the lungs. With a multifiber catheter, fluorescence spectra were recorded and evaluated using the most significant wavelength ratios. Correlation with histology showed the following sensitivities / specificities for the detection of malignant tissue: bladder 90% / 81%, brain 62% / 100%, lungs 80% / 76%. Compared to 5-ALA induced PPIX-fluorescence (bladder), a higher specificity was observed. The results obtained intraoperatively were compared with UV-imaging and spectroscopy on frozen tissue sections.
