The analysis of ultrasound diagnostics with Dopplerography in benign and malignant thyroid tumors

The thyroid gland is one of the most important organs of the endocrine system, and various tumors in this area can have serious consequences for human health. The main means of diagnosing such tumors is ultrasound with Dopplerography. The diagnosis of thyroid tumors is problematic, therefore, it is necessary to rely on imaging methods to diagnose a tumor. Contrast-enhanced ultrasound, as the most commonly used imaging method in modern clinical trials, is simple, safe, highly sensitive, can accurately display the tumor state and has high clinical value in the assessment of thyroid tumors. Purpose: to analyze the value of clinical application of ultrasound diagnostics and dopplerography in benign and malignant thyroid nodules.Methods. Ultrasound assessment was retrospectively applied to 211 preoperative thyroid patients selected for assessment using the ATA risk classification. Results. We identified 149 malignant nodes (70.6%) and 62 benign nodes (29.3%). More penetrating branching vascularization was found in the malignant group than in the benign group (145/149; 97.3% vs. 5/62; 8%). We also showed that according to the nature of blood flow in CHAMMAS, the central blood flow exceeded the perinodular blood flow (126/19, 87%/12,9%). Conclusions. Ultrasound diagnostics has high sensitivity and specificity for the assessment of thyroid tumors, and has high clinical diagnostic value.Keywords: ultrasound diagnostics, benign tumor, malignant tumor, CHAMMAS, ATA risk stratification.
