【Abstract】 ObjectiveTo explore the predictive effect color ultrasound appearance on malignant thyroid nodules.Methodsclinical data 62 patientswith thyroid nodulesadmited toour hospital fromJanuary 2022 toDecember2O23were retrospectively analyzed，andall patientsunderwent ultrasound examinationand postoperative pathological diagnosis.operative pathological results showed 12 benign and 5O malignant patients. Takingthe pathological diagnosisresultsas thegold standard，allthe patients were divided into benignnodulesand malignantnodules，andthecolorultrasound characteristics the two groupswerecompared.Using multivariate logisticregressionmodel analysis，thereceiveroperating characteristiccurve （ROC）curve was drawn to determine the predictive valueeach index inmalignant thyroidnodules.Resultssexandage patients in benignand malignant nodules were not significantly different （ P>0.05 ）. size the malignant nodule was lower than that the benign nodules （ P <0.05）. differences between the nodule composition，nodule internal echo intensity，nodule boundary，nodule morphology，nodule aspect ratio，and nodule calcification malignant nodules and benign nodules were comparable （ P <0.05）. surface area below the curve is followed from high to low by the nodule aspect ratio （0.875， P <0.001），the nodule morphology （0.869，P=0.032），the nodule boundary （0.867，P=0.003），the nodule calcification （0.8oo， P=O.0o3）， the nodule component （0.768， P=0.013 ），andthe internal echo intensity the nodule （0.732， P =0.082）.ConclusionIn the color ultrasound performance，nodule composition，nodule internal echo intensity，nodule boundary，nodule morphology，noduleaspect ratio，and nodule calcification can predictthe malignantrisk thyroidnodules，withthenoduleinternalechointensityhaving thesmalest weightandtheaspect ratio having the largest weight.

甲狀腺結(jié)節(jié)是臨床常見疾病，美國甲狀腺協(xié)會將其定義為“甲狀腺內(nèi)散在病灶，超聲或觸診可見清楚分界”。（剩余4760字）
