The aspect ratio of thyroid nodules is less than 1 and greater than 1. This description is considered to be a variability index of the thyroid nodule morphology and is also an important feature of malignant nodules. If the vertical axis of the nodule is larger than the horizontal axis, it indicates a chance of malignancy. Therefore, when you find such descriptions of B-ultrasound examination, please consult your doctor in time. What are the characteristics of malignant thyroid nodules?
Thyroid expert Li Jihua pointed out that in addition to the aspect ratio greater than 1, the characteristics of malignant thyroid nodules also have many aspects such as echo, blood flow, edge, size, and quantity in thyroid ultrasound examination, which need to be comprehensively considered when determining.
1. Microcalcification: Calcification refers to the calcium deposition phenomenon that occurs in the nodules. At present, microcalcification is a characteristic manifestation of thyroid cancer, which has been recognized by the medical community.
2. The boundary is unclear: The boundary of malignant thyroid tumors is very irregular and unclear, and it is prone to cancer.
3. Rich blood flow signal: The growth rate of malignant thyroid tumors is mostly abnormal, the blood flow rate is faster, and it is easy to increase and deteriorate quickly in a short period of time.
thyroid expert Li Jihua reminds patients: don’t just check regularly when you find nodules, but treat them in time, because nodules will not dissipate by themselves even if they are dragged. On the contrary, the nodules will continue to develop, and the more they dragged, the more serious they are dragged.
Of course, not all patients' nodules develop faster. There may be no obvious changes in the nodules in one or two years of reexamination, but no one can say that the nodules will worsen or become cancerous during the reexamination. No one can predict this in advance. What we can do is to intervene in time. Early dispersion is better than late surgery! #Follow Thyroid Nodules# #Thyroid Cancer#
