Moreover, these patients might also have normal conventional ultrasound findings. Aims: In our study, we aimed to distinguish the typical background characteristics of hashimoto thyroiditis using virtual touch tissue imaging quantification maps obtained with acoustic radiation force impulse imaging. Methods: Our study consisted of 28 hashimoto thyroiditis patients without characteristics of ultrasound findings and 28 healthy subjects. The thyroid parenchymal tissue mechanical properties were analyzed with the virtual touch tissue imaging quantification after ultrasound examination, and then related colored maps were obtained. Shear wave velocities were recorded (m/s) from the homogenous area where hardest and softest points were closest to each other on virtual touch tissue imaging quantification maps. The difference between the minimum and maximum shear wave velocities for each case (Δv) was calculated and recorded. Results: Assessment of virtual touch tissue imaging quantification maps revealed a significant difference between hashimoto thyroiditis and control groups in terms of maximum SWV’s, but no significant difference was observed between the minimum shear wave velocities (p Δv values were taken into account. In summary, the effects of chronic autoimmune thyroiditis can be distinguished by simply using Δv on virtual touch tissue imaging quantification maps. When the cut-off value of Δv was accepted 0.42, the diagnosis of hashimoto thyroiditis could be made with 88% accuracy. Conclusion: We suggest that shear wave velocities measurement on virtual touch tissue imaging quantification maps is a promising method in equivocal hashimoto thyroiditis cases, in which the diagnosis of hashimoto thyroiditis is unachievable with clinical, laboratory and conventional ultrasound findings.展开更多
