Fig. 4From: Efficacy of EUS-guided FNB using a Franseen needle for tissue acquisition and microsatellite instability evaluation in unresectable pancreatic lesionsEUS-FNA specimen obtained using a lancet-shaped needle. a The visibility of the 22-G lancet-shape needle was not much different from that of the Franseen needle. b In a low-power field, evident large tissue preparations were not observed. c In a high-power field, tumor cells were confirmed; however, there were not as many as in Fig. 3cBack to article page
