Objective To evaluate the performance of micro-flow imaging(MFI)in the
differential diagnosis of benign and malignant
thyroid nodules.
Methods Totally 50
patients with
thyroid nodules examined by conventional ultrasound,MFI,and contrast-enhanced ultrasound and confirmed by histological or cytological
pathology in the First Medical Center of
Chinese PLA
General Hospital from May to December in 2020 were enrolled in the study.The clinical data and ultrasound images were retrospectively analyzed.A binary
logistic regression model was established to evaluate the performance of the model in predicting benign and malignant
thyroid nodules. Results
Logistic regression showed that composition and "S-W-C" sign were independent
risk factors for predicting malignant
thyroid nodule.The
sensitivity,
specificity,and Youden index of the
logistic regression model were 73.33%,80.00%,and 0.53,respectively,and the area under
receiver operating characteristic curve was 0.799(95%CI=0.662-0.899). Conclusion MFI facilitates the
differential diagnosis of benign and malignant
thyroid nodules and has the potential to be applied in the
future.
