This research aims to learn more about thyroid nodules (lumps in the thyroid gland) using acoustic imaging (a type of sound picture) and viscoelastic parameters (how tissues move when pushed). The study compares new methods with standard ultrasound (US) to spot differences between malignant (cancerous) and benign (non-cancerous) nodules. It uses advanced tests like Shear Wave Ultrasound Vibrometry (SDUV) and Comb Push shear elastography (CUSE) to understand how nodules and neck lumps behave. The study also checks how well new ultrasound tools work, like the SuperSonic Imagine Aixplorer.

Key Points:

• Participants must be 8 years or older, with thyroid concerns or recurrence.
• This is an observational study, meaning no experimental treatments are given.
• Participants will undergo ultrasound imaging during the study.

The study is open to people with suspected thyroid cancer, those with detectable neck lumps, or patients diagnosed with recurrent thyroid cancer. Young children under 8 and those who had recent biopsies (tissue removal for testing) are not eligible.
