With the emphasis on health and quality of life, more and more people are opting for regular medical checkups, and now many medical checkups are making thyroid ultrasound a routine item, so how do you view the results of thyroid ultrasound. Before going into detail, it is important to emphasize that ultrasound is a relatively subjective test, which in layman’s terms means that the accuracy of ultrasound results depends heavily on the judgment and experience of the examining physician. After finding a swelling or nodule on the thyroid gland, it is important to pay attention to the words used to describe the nodule: 1. Echo: most malignant tumors are solid and hypoechoic internally, but not all hypoechoic ones are malignant. The number of nodules: most of them are multiple, some of them can also be single, and the number is generally not used as an evaluation indicator of malignancy or goodness; 3. On the contrary, those with clear borders and intact surrounding halo tend to be benign; 4.Longitudinal ratio: longitudinal ratio close to 1 is considered as possible malignancy; 5.Calcification: Calcified foci are generally divided into microcalcification, coarse calcification, and marginal calcification (circular calcification). Microcalcifications mostly appear as point-like strong echogenicity, which can be seen in 40%-61% of papillary carcinomas. However, it can also be seen in other benign and malignant lesions. Coarse calcification and marginal calcification are mostly seen in benign; 6. Blood flow: according to the distribution of blood flow inside and around the mass, there are four types: Type I: no internal blood flow; Type II: little internal blood flow; Type III: peripheral blood flow; Type IV: internal linear branching blood flow. Most of the malignant nodules have type III and type IV blood flow distribution. Most benign nodules have no blood flow or less blood flow; 7. Peripheral lymph nodes: If there is cystic attenuation or microcalcifications in the peripheral lymph nodes, suggesting metastasis, it can disprove that the mass on the thyroid is malignant; of course, as can be seen from the above, these indicators are not absolute individually, so the discovery of a thyroid mass should not be overly stressful. You should seek consultation with an experienced ultrasonographer and head and neck surgeon and face it positively!
