MRI-guided ultrasound treatment for skin cancer

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the safety and effectiveness of MRI-guided focused ultrasound combined with microbubble therapy and radiotherapy for patients with malignant melanoma and non-melanoma skin cancer. The approach utilizes low-power ultrasound to stimulate microbubbles in the tumor before administering radiation, aiming to enhance the therapeutic effect. The primary goal is to assess the safety profile of this combined treatment, while the secondary goal focuses on evaluating the tumor response through radiological measurements.
