Mapping tiny blood vessels inside thyroid nodules.

Microvascular Profiling of Nodules in the Thyroid Gland

Rigshospitalet, Denmark · NCT07041307

This project tries a super-resolution ultrasound scan to see if mapping tiny blood vessels can help doctors tell different kinds of thyroid nodules apart in adults with nodules or referred for surgery.

What this trial studies

Investigators will use Super-Resolution Ultrasound of Erythrocytes (SURE) to visualize and map microvascular networks in the thyroid gland and individual nodules at much higher resolution than conventional ultrasound. The observational imaging program will include adults with hypo-, iso-, or hyperfunctioning nodules, patients referred for thyroid surgery due to suspected malignancy, and healthy volunteers for comparison. Images will be analyzed for vessel size, density, and flow patterns to identify microvascular signatures that might differ between benign and malignant nodules and among functional classes. No experimental treatments are given; imaging findings will be compared to clinical follow-up and surgical pathology when available.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with hypo-, iso-, or hyperfunctioning thyroid nodules or patients referred for thyroid surgery due to suspected malignant nodules (Bethesda III-VI), as well as healthy volunteers without thyroid disease.

Not a fit: Patients who cannot undergo ultrasound, are pregnant, or already have a clear diagnosis and treatment plan are unlikely to gain direct benefit from participation.

Why it matters

Potential benefit: If successful, this technique could help doctors more accurately distinguish benign from malignant nodules and reduce unnecessary surgeries.

How similar studies have performed: Early pilot studies and preclinical work on super-resolution ultrasound show promise for visualizing tiny vessels, but clinical validation for distinguishing thyroid nodule types remains limited.
