The invention is applicable to the computer field, and provides an analysis method for of thyroid nodules. The analysis method includes the steps: receiving a thyroid nodule analysis parameter input by a user, wherein the thyroid nodule analysis parameter includes basic information of the user and basic information of a thyroid; and determining a malignant risk for thyroid nodules of the user according to the thyroid nodule analysis parameter and a thyroid nodule analysis model generated through training, and outputting the result, wherein the thyroid nodule analysis model is generated throughtraining based on a random forest algorithm or a neural network algorithm. The analysis method for thyroid nodules directly outputs the diagnosis result according to the relevant information input bythe user, and the diagnosis process is convenient and quick, and the thyroid nodule analysis model which is generated through training based on the random forest algorithm or the neural network algorithm, utilized in the diagnosis process can effectively guarantee the accuracy of the diagnosis results.
