Study on the diagnostic value of multimodal ultrasound in thyroid microcarcinoma / 中国基层医药

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<Kappa≤1.0). There was a high consistency between DU and gold standard (0.6<Kappa≤0.8). The sensitivity, specificity and diagnostic coincidence rate of multimode ultrasonic in the diagnosis of TMC were 97.52%, 91.94% and 95.96%, respectively.HFU and UE had high diagnostic value for TMC (AUC>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.
