In this prospective study, the diagnostic value of real-time ultrasound elastography (USE) was evaluated in 51 consecutive patients referred for surgical treatment with single solid thyroid nodules less than 10 mm in maximum diameter with an indeterminate result on B-mode and colour Doppler ultrasonography. Ultrasonographic results were compared with histopathological data. Nineteen follicular adenomas and 32 papillary thyroid microcarcinomas (PTMCs) were observed. A real-time USE score of 4 – 5 diagnosed PTMCs with a sensitivity of 90.63%, a specificity of 89.47% and an accuracy of 90.20%. The positive and negative predictive values were 93.55% and 85.00%, respectively. It is concluded that real-time USE is a promising imaging technique that could assist in the differential diagnosis of single solid thyroid nodules less than 10 mm in maximum diameter that give indeterminate results on conventional ultrasound.
