Ultrasound Evaluation of Thyroid Nodules Using ACR TI-RADS and Its Correlation with Cytopathology
Abstract: Thyroid nodules are commonly detected in clinical practice, yet only a small proportion are malignant, making accurate risk assessment essential for appropriate management. High-resolution ultrasound serves as the primary diagnostic tool, offering detailed evaluation of nodule characteristics. The ACR Thyroid Imaging Reporting and Data System provides a structured approach to classify nodules based on sonographic features and guide the need for fine needle aspiration cytology. A prospective observational study was conducted on fifty patients presenting with thyroid swelling, where ultrasound findings were categorized using ACR TI-RADS and correlated with cytological and histopathological results. The analysis showed a clear increase in malignancy risk with higher TI-RADS categories, while lower categories were largely associated with benign outcomes. Most suspicious ultrasound features demonstrated a meaningful association with malignancy, although certain mixed characteristics showed limited correlation. The findings support the clinical value of ACR TI-RADS as a consistent and practical method for risk stratification, helping reduce unnecessary invasive procedures and improving decision-making, especially in settings with limited resources.
