NCT06994260

Brief Summary

This clinical study evaluates the efficacy and accuracy of Multispectral Optoacoustic Tomography (MSOT) and Ultrasound Localization Microscopy (ULM) for imaging and diagnosing vascular malformations (venous, arteriovenous, lymphatic). The study aims to enhance diagnostic precision and improve treatment planning through advanced non-invasive imaging techniques.

Interventions

MSOT is an advanced imaging technology that combines laser-induced ultrasound and light absorption to visualize biological tissues. By detecting ultrasound waves generated from tissue absorption of multispectral light, MSOT provides high-resolution, real-time images with functional and molecular information. One of its use is in biomedical research and clinical applications to study blood oxygenation and tissue composition, making it valuable for areas such as vascular research. In this study, we aim to utilize MSOT to differentiate between venous, arteriovenous and lymphatic malformations.

Arteriovenous MalformationsLymphatic MalformationsVenous Malformation

ULM is a cutting-edge imaging technique that significantly enhances the resolution of traditional ultrasound by tracking the movement of microbubble contrast agents within blood vessels. This approach enables the visualization of microvascular structures and blood flow dynamics at a super-resolution scale, beyond the diffraction limit of conventional ultrasound. In this study, we aim to utilize ULM to differentiate between venous, arteriovenous and lymphatic malformations.

Sampling MethodNon-Probability Sample
Study Population

The study population consists of patients (≥18 years old) with diagnosed vascular malformations. These may be of lymphatic, venous, or arteriovenous origin.

You may qualify if:

  • Confirmed vascular malformations (arteriovenous, venous, or lymphatic).
  • ≥18 years old and able to give their consent

You may not qualify if:

  • No imaging for diagnostic confirmation has been performed or is planned.
  • Lack of written consent
  • \<18 years old
  • Safety concerns of the study physician (a patient with physical, psychological, or psychiatric conditions that, in the opinion of the study physician, could compromise the patient's safety or the quality of the data, thereby making the patient an unsuitable candidate for the study).
