    as TI-RADS 4 type by conventional ultrasound examination，who were admitted to Shangrao People's Hospital from January2020 to January 2023were selected， and all patients underwent CEUS examination.Using cytological examination results as the gold standard， benign nodules were included in the benign group ( n =69) and malignant nodules were included in the malignant group ( n =49).The CEUS parameters (rise time， time to peak and mean transition time)of thetwo groups werecompared，and thevalue of CEUS indifferential diagnosis of benign and malignant TI-RADS type 4 thyroid micronodules was analyzed by receiver operating characteristic (ROC) curve.
