Abbreviations: Gr. Dim = Greatest Dimension, SUVmax = Maximum standardized uptake value, FVPTC = follicular variant of papillary thyroid carcinoma, Nod hyp = nodular hyperplasia, FA = follicular adenoma, PTC = papillary thyroid carcinoma, FC = follicular carcinoma, ca = carcinoma, NR = not reported, inc = incidental. For a lesion to be characterized as solid on imaging, the ultrasound report must have characterized the lesion as “solid” or “predominantly solid”.
