Standardized Ultrasound Report for Thyroid Nodules: The Endocrinologist's Viewpoint

Accuracy of ultrasonography-guided fine needle aspiration cytology and significance of non-diagnostic cytology in the preoperative detection of thyroid malignancy

“…(7) Any one feature would classify the nodule as sonographically suspicious. (8)(9)(10)(11)(12) Borders were classified as circumscribed or ill-defined (depending on how clearly the margin was demarcated), and regular or irregular (depending on the presence of spiculations or microlobulations). Ill-defined nodules were defined as those with an indistinct demarcation between the tumour and the surrounding normal glandular tissue or nodules whose margins could not be obviously differentiated from the adjacent thyroid tissue.…”

“…Ill-defined nodules were defined as those with an indistinct demarcation between the tumour and the surrounding normal glandular tissue or nodules whose margins could not be obviously differentiated from the adjacent thyroid tissue. (8,9) The border was deemed to be irregular or ill-defined if any one of the few representative ultrasonography images showed a part of the border as irregular or unclear. Thyroid nodules were classified as hypoechoic, isoechoic or hyperechoic relative to thyroid parenchyma, with marked hypoechogenicity defined as being darker than the infrahyoid or strap muscles.…”

“…(8) Calcifications were classified as microcalcifications (punctate hyperechoic spots less than 1 mm without posterior acoustic shadowing) or coarse calcifications (larger echogenic foci with posterior shadowing). (8,9) A nodule was taller than wide if its anteroposterior dimension was greater than its transverse dimension. (8) At our institution, thyroid nodules were selected for FNAC if they demonstrated any one sonographically suspicious feature.…”

“…Eine glatte oder lediglich unscharfe Begrenzung zwischen solidem und zystischem Anteil weist auf Benignität hin, eine mikrolobulierte Begrenzung auf Malignität, v. a. in Kombination mit Mikrokalzifikationen des soliden Anteils [49], [50]. Weitere Bildbeispiele in [49], [50], [51]. Dignitätsbeurteilung: Taller-than-wide ist zwar ein wenig sensitives, aber hochspezifisches und hochsuspektes Kriterium [56], [57].…”

Diagnostic accuracy of sonography in assessment of thyroid masses in comparison with pathology

“…In brief, echogenicity of the thyroid nodule was measured by comparing echogenicity of the thyroid parenchyma and cervical muscle, and was classified as markedly hypoechoic, showing fairly more hypoechoic than adjacent cervical muscle, hypoechoic, showing relatively more hypoechoic than normal thyroid parenchyma, isoechoic, showing isoechoic to normal thyroid parenchyma, or hyperechoic, showing relatively more hyperechoic than adjacent normal thyroid parenchyma. Thyroid nodular vascularity was assessed and classified based on the standardized ultrasound report for thyroid nodules [10].…”
