Thyroid imaging examination can Help us understand the size, number, size, shape and function of thyroid tumors. Imaging examinations include thyroid radionuclide imaging, thyroid gamma photography, thyroid B-mode ultrasonic examination, thyroid tomography (CT) and magnetic resonance imaging (MRI) examination. · Thyroid ultrasound examination: Thyroid B-mode ultrasound examination is far superior to X-rays, CT or MRI due to its high resolution of soft tissue. At the same time, it has good repeatability and non-invasive characteristics, making it more and more widely used in clinical applications. Thyroid type B has high sensitivity and can distinguish lesions as small as 3 mm; however, its specificity is low and cannot effectively distinguish between benign and malignant lesions. · Thyroid radionuclide imaging: The thyroid gland has the function of concentrating iodine and technetium. The patient is allowed to take radioactive iodine or technetium, and with the help of a radionuclide imaging detection probe, the distribution map of radioactive tracer uptake in the thyroid can be obtained in vitro. The function of absorbing iodine or technetium in various parts of the thyroid gland is clearly shown. According to the difference in image radiation intensity and compared with the radiation intensity of normal tissue, it is divided into three types: "hot nodules", "warm nodules" and "cold nodules". It is helpful to understand the location, shape, nodule, size and function of the thyroid gland. ·Thyroid gamma photography: The basic principle of thyroid gamma photography is the same as that of thyroid radionuclide imaging. It is a three-dimensional scanning image, so it is more accurate to judge thyroid tumors than thyroid radionuclide scanning (two-dimensional plane image). At the same time, it can Shows the blood flow in various parts of the thyroid gland. ·Thyroid CT and MRI examination: The emergence of CT and MRI provides a very powerful tool for clinical detection of tumors. Similarly, CT and MRI are also of great significance in the localization of thyroid tumors, but lack characteristic changes. Due to its high price and inconvenient examination, it is not an ideal examination method for thyroid tumors. ·Thyroid fine-needle aspiration cytology: Fine-needle aspiration cytology has been used in thyroid diseases for more than 20 years, and a lot of clinical experience has been accumulated. Research data shows that thyroid fine-needle aspiration is ideal for distinguishing benign and malignant thyroid tumors, and is also very beneficial for the diagnosis of chronic thyroiditis. ·Thyroid biopsy: Thyroid biopsy is very accurate in diagnosing thyroid tumors, but the rich blood supply of the thyroid gland makes biopsy very difficult, and this method is not easily accepted by patients.
