Study on the diagnostic value of multimodal ultrasound in thyroid microcarcinoma

Abstract

Objective To study the diagnostic value of multimodal ultrasound in thyroid microcarcinoma(TMC). Methods The clinical data of 203 TMC patients in the Sixth Hospital of Shanxi Medical University from March 2015 to January 2019 were retrospectively analyzed.The preoperative multimodal ultrasound results [high frequency ultrasonography(HFU), color Doppler (DU), ultrasonic elastography (UE)] were collected, the postoperative pathological results were seen as the gold standard, and the consistency of multimodal ultrasound diagnosis and the pathological results was analyzed, the diagnosis effect index of multimodal ultrasound was calculated, ROC curve was used to analyze the diagnostic value of multimodal ultrasound for TMC. Results The diagnostic results of HFU, UE were highly consistent with the postoperative pathological results (0.8 0.9). DU had medium diagnostic value for TMC (0.7≤AUC≤0.9). Conclusion Multimodal ultrasonography has high diagnostic value for TMC, and it can be used in many fields such as clinical diagnosis, efficacy evaluation and reexamination due to its good repeatability and non-invasive.
