Thyroid nodules with strong echogenicity, increased blood flow and clear borders are usually less likely to be malignant and more likely to be benign. Thyroid nodules should be graded by TIRADS by the doctor to assess the benign or malignant nature, and if necessary, the benign or malignant nature of the nodule can be clarified by puncture pathology. For malignant thyroid nodules, ultrasound of the neck usually shows solid hypoechoic nodules, irregular shape, unclear border, abundant blood flow signal, aspect ratio greater than one, and calcification within the nodule, etc., which can be graded by TIRADS to assess the benign or malignant nature. If the color ultrasound examination of thyroid nodules shows strong echoes, increased blood flow and clear borders, it means that the nodules are more likely to be benign. It is recommended to consult the doctor in time to improve the thyroid function, and if necessary, improve the thyroid pathology to clarify the nature of the nodule.
