Abstract：Objective: To explore a kind of technology, which can make the two tissue boundary whose acoustic impedance coefficient is very close to display clearly. Methods: Randomly selected 77 cases to resection of thyroid nodules or puncture. Firstly, the routine examination method to obtain TI-RADS diagnosis and entry control group, using conventional with gray scale adjustment technology to calculate TI-RADS diagnosis and entry intervention group, when each patient in preoperative ultrasonography. The two groups were drawn into the form of ultrasound diagnosis. The postoperative pathological report of each patient was followed up. Results: Compared two groups of ultrasound diagnosis and pathologic report compliance, that routine with gray scale adjustment technology is better than conventional examination in accuracy, specificity and sensitivity, the difference is statistically significant. Conclusion: Ultrasound local gray scale adjustment technology can help doctors to determine the nature of the thyroid nodule ultrasound.
