Categorias num relance

Cat.SignificadoCondutaRiscoFonte
1
K-TIRADS 1, no nodule
No nodule: the thyroid contains no discrete nodule on ultrasound.
Not applicable (no nodule to sample).Malignancy risk is not applicable because no discrete thyroid nodule is present to stratify.
PMC4842857 (Shin et al., Korean J Radiol 2016;17(3):370) Table 2, category labelled 'no nodule'
2
K-TIRADS 2, benign
Benign: spongiform nodule, partially cystic nodule with a comet-tail artifact, or a pure (simple) cyst.
Diagnostic FNA may be considered selectively when the nodule is 2 cm or larger; otherwise FNA is not indicated.Estimated malignancy risk under about 3% (under roughly 1% for an isoechoic spongiform nodule).
PMC4842857 Table 2 (benign category) and Indications/Management text
3
K-TIRADS 3, low suspicion
Low suspicion: a partially cystic or iso-/hyperechoic nodule that lacks all three suspicious ultrasound features (microcalcification, non-parallel/taller-than-wide orientation, spiculated or microlobulated margin).
FNA recommended when the nodule is 1.5 cm or larger.Estimated malignancy risk approximately 3-15%.
PMC4842857 Table 2 (low-suspicion category) and Indications text
4
K-TIRADS 4, intermediate suspicion
Intermediate suspicion: a solid hypoechoic nodule without any suspicious feature, or a partially cystic / iso- or hyperechoic nodule that has any one of the three suspicious ultrasound features.
FNA recommended when the nodule is 1 cm or larger.Estimated malignancy risk approximately 15-50%.
PMC4842857 Table 2 (intermediate-suspicion category) and Indications text
5
K-TIRADS 5, high suspicion
High suspicion: a solid hypoechoic nodule that has any of the three suspicious ultrasound features (microcalcification, non-parallel/taller-than-wide orientation, or spiculated/microlobulated margin).
FNA recommended when the nodule is 1 cm or larger; selective FNA may be considered above 0.5 cm.Estimated malignancy risk above about 60%.
PMC4842857 Table 2 (high-suspicion category) and Indications text
