Is the aspect ratio of thyroid nodules greater than 1 serious?

A thyroid nodule aspect ratio greater than 1 indicates malignancy and requires further examination and evaluation. A thyroid nodule aspect ratio greater than 1 indicates malignancy and requires further examination and evaluation. The thyroid nodule aspect ratio is the ratio of the anteroposterior diameter to the left-right diameter of the nodule. When the aspect ratio is greater than 1, it means that the length of the nodule in the anteroposterior direction is greater than that in the left-right direction, showing the characteristics of longitudinal growth. This morphological feature is consistent with some characteristics of malignant nodules, such as irregular edges and invasion of surrounding tissues. However, it should be noted that aspect ratio is only an indicator for evaluating thyroid nodules and cannot be used as a basis for diagnosing malignant nodules alone. Other factors such as nodule size, shape, boundary, calcification, etc. need to be considered comprehensively. In addition, doctors will also combine the patient's personal circumstances, such as age, gender, family history, thyroid function, etc., to determine the nature of nodules. For patients who find thyroid nodules with an aspect ratio greater than 1, doctors usually recommend the following further tests: 1. Fine needle aspiration biopsy: This is a minimally invasive test in which cells are removed from the nodule by a fine needle for pathological analysis to determine the nature of the nodule. 2. Ultrasound: You can understand the characteristics of nodules in more detail, including size, shape, blood flow, etc., to help doctors assess the benign or malignant nodules. 3. Other tests: Depending on the specific situation, doctors may also recommend thyroid function tests, radionuclide scans, etc. If the fine needle biopsy results suggest malignant nodules, further treatment is usually required, such as surgical resection, radioactive iodine therapy, etc. If the nodule is finally diagnosed as benign, the doctor will develop a follow-up plan based on the size and growth of the nodule. Ultrasound will be performed regularly to monitor the nodule changes. It is important to emphasize that the management of thyroid nodules should follow the principle of individualization. Patients should fully communicate with their doctors to understand the pros and cons of various examinations and treatments, and make decisions based on their own circumstances. In addition, maintaining good lifestyle habits, such as healthy diet, moderate exercise, and reducing radiation exposure, are also important for thyroid health. In summary, thyroid nodules with an aspect ratio greater than 1 indicate that nodules may be malignant, but other factors need to be evaluated. Patients should seek medical attention promptly and follow the doctor's recommendations for further examination and treatment.
