Whether a nodular strong echo of a thyroid nodule is malignant or not needs to be determined by the patient’s tumor growth rate, size, borders, blood flow signal, and calcification. The presence of punctate strong echoes in a simple thyroid nodule is an ultrasound imaging manifestation that suggests the possible presence of calcification of the thyroid nodule, but the presence of calcification is not diagnostic of a malignant tumor of the thyroid gland, and calcification can be a problem in benign nodules as well. In thyroid ultrasonography, the presence of punctate echoes in the thyroid gland should be evaluated to determine the size of the echoes, the presence of calcification, the aspect ratio, and the clarity of the border of the blood flow signals to assess whether there is a malignant tumor of the thyroid gland. If malignant tumor of the thyroid is suspected, it is recommended to consult the thyroid surgery department of a regular hospital.
