Palpatory and Ultrasonographic Assessment of Tissue Compressibility: Validation and Learning Effects in Phantom Models
Switzerland40 participantsStarted 2026-01-31
Plain-language summary
This validation study compares clinical palpation and ultrasonographic measurements of tissue compressibility using standardized phantom models. Operators with different levels of clinical and ultrasound experience perform repeated, blinded assessments across multiple sessions. The study evaluates accuracy, reliability, agreement between modalities, and learning effects over time, aiming to support standardized and more objective assessment of tissue compressibility in clinical practice.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This study is focused on palpation and ultrasound compression measurements using phantom models rather than treating a disease — can you help me understand whether participating would offer me any direct medical benefit, or is this purely a methods-validation study?
2Since this trial is listed as 'active not recruiting,' does that mean enrollment is already closed, and if so, are there similar studies you're aware of that I could still join?
3The study seems to involve practicing and measuring tissue examination techniques — what exactly would be done to me physically during participation, and are there any discomfort or risks associated with repeated ultrasound compression or palpation procedures?
4Because this is a Phase N/A study focused on validating measurement tools rather than testing a treatment, how does this fit into my overall care plan, and would my time be better spent pursuing a treatment-focused trial instead?
5If the goal is to improve how accurately doctors detect tissue changes through touch and ultrasound, could the findings from this kind of research eventually affect how my own condition is monitored or diagnosed in the future?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
