Realtime-Elastography (RTE) and Thyroid Nodules
Recruitment status was: Recruiting
The study is an open, prospective multicenter study. According to the statistical sample size calculation 593 patients with thyroid nodules ≥ 5mm in size will be included in the study. Reference methods are cytology obtained by Fine needle aspiration biopsy (FNAB) or histology obtained by surgery.
All patients will receive an B-mode and Duplex ultrasound examination of the thyroid gland, as well as Realtime Elastography of thyroid nodules.
Results of B-mode and Duplex ultrasound are compared to Realtime Elastography to evaluate the additional value of Realtime Elastography in the diagnostic work up of thyroid nodules.
Device: Realtime-Elastography, linear ultrasound probe, Hitachi EUB-900, Japan
Procedure: Cytology (FNAB) or Surgery
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
|Official Title:||Evaluation of Realtime-Elastography for Differentiation of Thyroid Nodules: a Multicenter Study|
- Realtime-Elastography scores I-IV in thyroid nodulesScores: I-II: benign; III-IV: malignant nodules. The sensitivity and specificity of Realtime-Elastography for the diagnosis of malignant thyroid nodules will be calculated on the basis of above-specified criteria. Cytology is used as reference method for benign nodules and histology for malignant nodules.
- Comparison of Realtime-Elastography with B-mode and Duplex-Ultrasonography concerning the additional diagnostic information obtained by Realtime-Elastography
