Deviations of template-guided FNA. The deviations of template-guided FNA were demonstrated three-dimensionally (A). Positive values for CD, AD, or SD indicated that the biopsy needle deviated medially, anteriorly, or cranially, respectively. The deviations in each dimension were further compared (B). The horizontal line in each box indicates the median, while the top and bottom borders of each box indicate the 75th and 25th percentiles, respectively. The ends of the whiskers above and below each box indicate the minimum and maximum values. FNA, fine-needle aspiration; CD, coronal deviation; AD, axial deviation; SD, sagittal deviation.
