Unnodule thyroïdien est classé EU-TIRADS 5 à partir du moment où il existe un ou plusieurs signes forts parmi : contours irréguliers, fortement hypoéchogène, microcalcifications, forme non ovalaire. En fonction du nombre de critères le risque de malignité varie entre 26 et 87%. Précédent. Suivant. depth 1.3-2 cm; isthmus ≤0.5 cm deep; Thyroid volume can be estimated by measuring each lobe and applying the following correction factor for an ellipsoid formula 6: height (cm) x width (cm) x depth (cm) x 0.529* * various correction factors between have also been proposed 6,9. History and etymology Forstatistical analysis, ACR TI-RADS 2, 3 and 4a nodules, “very low”, “low” and “intermediate suspicion” nodules by ATA guidelines and Bethesda III were considered favorable / negative while ACR TI-RADS 4b, 4c and 5 nodules, “high suspicion” nodules and Bethesda IV and V were considered unfavorable / positive, according to the likelihood of Classificaçãoconforme Associação Americana de Tireoide (ATA) Suspeita para câncer Recomendação para PAAF (tamanho) Benigno Não recomendação para PAAF indicação de seguimento TI-RADS 1 Benigno 0,3% Não TI-RADS 2 não-suspeito 1,5% Não TI-RADS 3 Baixa 4,8% ≥ 2,5 cm ≥ 1,5 cm TI-RADS 4 moderada 9,1% ≥ 1 ,5 cm ≥ 1,0 cm Lapuntuación de todos los nódulos tiroideos benignos (TI-RADS 2) o probablemente benignos (TI-RADS 3) fue cero. En el grupo TI-RADS 3 sólo un 2 2% de los NT fueron malignos. La escala de puntos de TI-RADS 4a, 4b y 4c fue, respectivamente, de uno, dos y tres-cuatro puntos, con una incidencia de malignidad del 9.5%, 48% y 85%.

Resumo: 1Danh mục TI-RADS (TI-RADS categories) Năm đặc điểm siêu âm của nhân giáp được sử dụng trong TI-RADS là: thành phần, độ hồi âm, hình dạng, đường bờ và những đốm hồi âm dày. Mỗi mục Recommendations EU-TIRADS 2: no FNA required (unless for theraputic purpose / relieve compression) EU-TIRADS 3: >20 mm FNA. EU-TIRADS 4: >15 mm CTneck. ct. There is a large low-density nodule in the left thyroid lobe, with imperceptible walls, without calcifications or internal septae. In addition, several smaller hypodense nodules are seen in the right thyroid lobe. Forexample, a TI-RADS 1 (T1) or TI-RADS 2 (T2) nodule has a risk of malignancy of less than 5 per cent, whereas, in the TI-RADS 5 (T5) category, more than 80 per cent of nodules are malignant 2. Clinical practice guidelines recommend FNA for TI-RADS 4 (T4) or T5 nodules greater than or equal to 1 cm, for TI-RADS 3 (T3) nodules TheAmerican College of Radiologists (ACR) incidental findings and Thyroid Imaging Reporting and Data System (ACR TIRADS) committees have provided guidance for EUTIRADS 3 >20mm EU-TIRADS 5 >10mm -TIRADS 4 >15mm ÃO REFERENCIAÇÃO (Iodo-131 ou Cirurgia) VIGILÂNCIA NÓDULOS TIROIDEUS Bibliografia: European Thyroid Association Guidelines for Ultrasound Malignancy Risk Stratification of Thyroid Nodules in Adults: The EU-TIRADS (2017) Therefore the specificity of TI-RADS categories 2 (4.7%) and 3 (30.7%) in labelling a nodule as benign was found to be 100%. The estimated decrease in unnecessary FNACs in our study was found to be 35.43%. Specificity of ACR TI-RADS category TR1 and TR2 in labelling a nodule as benign was also found to be 100%.
