Zusammenfassung
Strain elastography is a diagnostic method that adds quality in the evaluation of benign versus malignant thyroid nodules. Meta-analysis are suggesting overall sensitivity of 0.85 with a pooled specificity of 0.80. The present study is a retrospective analysis of the main causes of false positive and false negative results in thyroid nodular disease. Material and method: 433 thyroid nodules, that were operated, were evaluated by conventional ultrasound and real time elastography (RTE), with linear multifrequency probe, Hitachi Preirus Machine, Hitachi Inc., Japan: qualitative (Rago criteria) and semiquantitative…
