Study summary

After thyroid ablation procedure, the volume of the thyroid nodule (s) needs to be measured to see how well the procedure worked. Currently, these volumes are measured using traditional 2D ultrasound imaging. However, this approach comes with limitations because of the information 2D images cannot gather and because of differences in these measurements between different doctors. A new ultrasound technology called PIUR 3D imaging offers a novel alternative approach. The system uses advanced technology to create 3D images and can generate automated volume estimates. The PIUR imaging system, PIUR tUS Infinity, has been cleared by the Food and Drug Administration (FDA) to aid in treatment decisions when used alongside traditional 2D ultrasound imaging.

The purpose of this study is to test how effective and consistent the PIUR imaging technology is compared to standard 2D ultrasound in measuring thyroid nodule volume.

Read the detailed description

PIUR imaging technology, cleared by the U.S. Food and Drug Administration under 510(k) (K240036), is designed to provide advanced volumetric imaging capabilities to improve accuracy in assessing nodule size and volume reduction. This technology has been validated for clinical use and shown to be equivalent to conventional methods. Currently, PIUR is intended to complement the diagnostic process and should not be used as the sole basis for treatment decisions. Instead, it serves as an adjunct to standard 2D ultrasound imaging.⁸ These features make PIUR a potential candidate for post-ablation monitoring of thyroid nodules, where precision and reproducibility are critical.

This study aims to compare the volume reduction rates obtained using PIUR imaging against those calculated by an experienced clinician using traditional 2D ultrasound. The findings will help assess whether PIUR offers a more reliable, operator-independent method for evaluating treatment outcomes following thyroid nodule ablation.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Thyroid nodule volumetric measurements

    Compare thyroid nodule volumetric measurement readings retrieved from the PIUR 3D ultrasound and the volume calculated from a 2D ultrasound among patients having a thyroid ablation

    Time frame: Will occur at baseline, 2 weeks, 1 month, 3 months, 6 months, and 1 year

  2. Comparison of variability between measurements

    Compare the variability in the thyroid nodule volume measurements between the PIUR 3D ultrasound and the variability calculated from a 2D ultrasound among patients having a thyroid ablation

    Time frame: Will occur at baseline, 2 weeks, 1 month, 3 months, 6 months, and 1 year

  3. Post-ablation thyroid volume reduction rate comparison

    Evaluate post-ablation thyroid volume reduction rates at 2 weeks and 1-, 3-, 6-, and 12 months in patients undergoing thyroid ablation and receiving PIUR 3D ultrasounds as compared to standard 2D ultrasounds.

    Time frame: 2 weeks, 1-, 3-, 6-, and 12 months.
