Soft Tissue Lesion

The goal of this observational registry is to assess the use and performance of Galvanize PEF technology in a real-world setting. The main questions it aims to answer are: * PEF utilization and performance * Monitor safety outcomes and inform future generation devices. Participants will undergo the PEF procedure and be followed per institutional standard of care.

This is a first-in-human, pilot study of the novel PET-imaging radiotracer \[89Zr\]DFO-starPEG. The study is designed to obtain preliminary data to support future development of this agent as an imaging surrogate to visualize enhanced permeability and retention (EPR)-mediated tracer uptake before administration of EPR-based nanomedicines.

A registry to audit the current range of applications, technical success rate, safety profile, complication rate and efficacy of cryoablation procedures being performed in children.
