VivaScope sensitivity was 100%, specificity was 66.7%, accuracy was 97%, positive predictive value was 97%, and negative predictive value was 100%.
The VivaScope 2500 represents a new technique that can be successfully applied to cytological microhistological specimens. It provides immediate information on the suitability of the tissue and shows very good agreement with the final histology. In a subsequent study, EUS-FNA/FNB VivaScope images were evaluated by pathologists from 10 international centers to investigate the concordance between the observers with the final diagnostic report.
