Abstract

Background: The goal of ultrasound guided fine-needle aspiration (USFNA) is to obtain most cellular specimen that represents the nodule. However, there is substantial variability in specimen cellularity depending on the obtaining techniques. While performing USFNA, it is not clear whether the needle tip should be placed at hypovascular or hypervascular site of the nodule to obtain more cells for cytological analysis.
