ABSTRACT

Objective To explore the ultrasonic imaging features of malignant thyroid nodules risk fac-tors by logistic regression.Methods Two hundreds and forty patients with thyroid nodules by ultrasonic examina-tion and surgical treatment for patients with definited pathological diagnosis were included in this study.The pre-operative sonographic features of the nodules were put into the logistic regression model to explore the risk factors of ultrasonic imaging features of malignant thyroid nodules.Results By logistic regression model analysis,hypoe-cho,taller than wide≥1 and micro calcification were found to be significantly statistical variables for thyroid car-cinoma.Micro calcification could predict thyroid cancer for lymph node metastases.Conclusoin During clinical diagnosis,hypoecho,taller than wide more than 1 and micro calcification could be used as indicators by ultrasound doctors to judge malignant thyroid nodules and lymph node metastases.Prospective larger similar research is still very necessary to explore the indicator for thyroid carcinoma in the future.
