The present study explored the efficiency of shear wave elastography (SWE) in diagnosing papillary thyroid microcarcinoma (PTMC).
METHODS:
This retrospective study constituted of 446 patients with 510 thyroid nodules. SWE values and ultrasound parameters of each nodule were used for comparison and analysis.
RESULTS:
The ultrasonography findings between malignant and benign nodules differed significantly ( 0.05). The benign and PTMC nodule groups showed a remarkable difference in the stiffness, i.e., higher SWE values.
CONCLUSION:
SWE is useful in diagnosing micro thyroid nodules, and the values were significantly correlated with tumor size and thyroid capsule invasion of PTMC.
