Autofluorescence imaging is becoming more and more important in the assessment of the severity of a variety of diseases. Recently, researchers from Vojvodina, Clinic for Pulmonary Oncology, Serbia, have shown the benefits of autofluorescence imaging videobronchoscopy (AFI). AFI is one of the new systems of autofluorescence bronchoscopy designed for thorough examination of bronchial mucosa. Indications for AFI go from evaluation of early-stage lung cancer and detection of precancerous lesions, to evaluation of tumor extension or follow-up after surgical resection. This technique provides clear differentiation between normal and pathologically altered mucosa. However, AFI has a low specificity in the detection of premalignant lesions, early-stage lung cancer. According to the researchers, this disadvantage could be overcome by addition of backscattered light analysis, ultraviolet spectra, fluorescence-reflectance or dual digital systems. In addition, quantitative image analysis is also required to reduce intra and inter-observer variability in the assessment of the disease.
