AdoptingACR TI-RADS may require practice-level changes involving image acquisition and workflow, interpretation, and reporting. Significant resources should be devoted to educating sonographers and radiologists to accurately recognize features that contribute to the scoring of a nodule. Following a system that uses approved terminology TesslerFN, Middleton WD, Grant EG et al. ACR Thyroid Imaging, Reporting and Data System (TI-RADS): White Paper of the ACR TI-RADS Committee. J Am Coll Radiol. 2017; 14: 587-595. Grant EG, Tessler FN, Hoang JK et al. Thyroid Ultrasound Reporting Lexicon: White Paper of the ACR Thyroid Imaging, Reporting and Data System (TIRADS) Committee. Amongthe 45 ACR TI-RADS 4 nodules and 21 ACR TI-RADS 5 nodules that were surgically excised owing to patient preference, 13 ACR TI-RADS 4 nodules and 6 ACR TI-RADS 5 nodules were initially not recommended for FNAC. Of these nodules not recommended for FNAC, cancer was eventually proven in 4 of 13 (30.7%) and 3 of 6 nodules (50.0%), respectively. TheACR TI-RADS is designed to balance the benefit of identifying clinically important cancers against the risk and cost of subjecting patients with benign nodules or TIRADS 1: nódulo benigno, com risco de malignidade de 0,3%. TI-RADS 2: nódulo não-suspeito, com risco de malignidade de 1,5%. TI-RADS 3: nódulo pouco suspeito, com risco de TheACR TI-RADS does not recommend re-imaging of TR1–2 nodules or smaller TR3–5 nodules (TR3 nodule <1.5 cm, TR4 nodule <1 cm, TR5 nodule <0.5 cm) (Table 1).19 Clinicians may consider re-imaging of TR1–2 nodules at 24-month intervals and the smaller TR3–5 nodules at 12–24-month intervals.2,17 Routine follow-up of purely cystic or spongiform Consideraçõesfinais: A tireoglobulina e a antitireoglobulina são marcadores tumorais com papel fundamental para seguimento de pacientes após tratamento cirúrgico de câncer de tireoide Inthis article, the authors present the ACR TI-RADS Committee’s recommendations, which provide guidance regarding management of thyroid nodules on the basis of their ultrasound appearance. The authors also describe the committee’s future directions. Key Words: Thyroid nodule, thyroid cancer, management guidelines, ultrasound. TheAmerican College of Radiology incidental findings and Thyroid Imaging Reporting and Data System (TI-RADS™) committees have provided guidance for reporting findings and providing recommendations for the management of patients with thyroid nodules, and these interventions have significantly reduced performance of unnecessary thyroid biopsies Acorrelation study of ACR TI-RADS with FNA cytology in the evaluation of thyroid nodules.

TheAmerican College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) is a reporting system for the evaluation of thyroid nodule by ultrasound (US) to determine management [].ACR TI-RADS is founded on the evaluation of five categories seen by the US, this includes composition, echogenicity, shape, margin, and echogenic foci; each ogy and 38.4% benign. According to the TI-RADS risk category, 50% of those with high suspicion were malignant, 13.3% suspicious for malignancy cytology and 36.7% were benign. Thyroidnodules are highly prevalent; about one third of the adult population has thyroid nodules on ultrasonographic (US) examination (1, 2).However, less than 10% of them are malignant (3, 4).Several US characteristics have been proposed to identify nodules at risk for being malignant (5, 6).Most authors divide thyroid nodules into benign (colloid) nodules, DiagnosticPerformance of Different Thyroid Imaging Reporting and Data Systems (Kwak-TIRADS, EU-TIRADS and ACR TI-RADS) for Risk Stratification of Small Thyroid Nodules (≤10 mm) Simone Schenke, 1, 2, * Rigobert Klett, 2 Philipp Seifert, 3 Michael C. Kreissl, 1 Rainer Görges, 4 and Michael Zimny 2 ABSTRACTObjective: The aim of this study was to determine whether classifying hypoechogenicity in three degrees (mild, moderate, and marked) could improve the distinction between benign and malignant nodules and whether such an approach could influence Category 4 of the Thyroid Imaging Reporting and Data System (TI-RADS).
