My thyroid lab work abnormal, had a scan results are: isthmus is mildly thickened measuring 5.0mm in diameter, the right lobe measured 4.5x1.5x1.4cm, the left lobe measures, 4.9x1.4x1.0cm. Both lobes demonstrate a moderately echo pattern, color Doppler demonstrating mildly increased vascularity bilaterally focal calcification measuring 3mm identified on mid right lobe I do have hoshimodos what does this scan mean?
