Figure 1

Recording of the ultrasonographic intensities and calculation of the thyroid heterogeneity index (HI). The appropriate sampling points were first determined for measuring. Four open-circle cursors (2 mm in diameter) per half lobe were positioned straight along a horizontal line at the depth of the right common carotid artery adjacent to the thyroid gland. US intensity within each circle was automatically calculated immediately after the cursor was set. HI was defined as the CV (i.e., SD/mean) of eight US intensities.
