Thyroid nodules surrounded by blood vessels are mainly suggestive of a certain blood supply, and the specific conditions need to be combined with other indicators to determine the overall situation; benign indications are relatively good conditions; malignant indications are mostly bad conditions. 1. The edge of the corresponding nodule is smooth, the density is uniform, the border is clear, the aspect ratio is less than 1, the whole belongs to benign signs, the possibility of malignancy is relatively small, belongs to the relatively good condition. 2. If the edges of the nodules are not smooth, lobulated, with uneven density, fuzzy borders, and the aspect ratio is greater than 1, accompanied by amorphous calcification, there are more malignant signs, and further puncture biopsy is needed to clarify the benign and malignant nature of the nodules. The benign or malignant nature of thyroid nodules needs to be combined with the ultrasound indicators to make a comprehensive judgment, and standardized treatment under the guidance of clinicians to avoid delaying the condition.
