Realtime-Elastography (RTE) and Thyroid Nodules

Evaluation of Realtime-Elastography for Differentiation of Thyroid Nodules: a Multicenter Study

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.

Inclusion Criteria:

• patients with thyroid nodules ≥ 5mm in size and TSH ≥ 0,35µU/ml
• Cytology obtained by FNAB or thyroid surgery planned
• age ≥ 18 year
• signed written consent

Exclusion Criteria:

• Diseases which preclude study accomplishment or put the patient at any risk (e.g. psychiatric diseases)
• Non-contractually capable persons
• Pregnancy
• Lactation
