qDSA Blood Flow Measurement in Patients Undergoing TAE of the Liver
University of Wisconsin, Madison
Start Date

Completion Date
12/1/2026
Summary
The purpose of this research is to evaluate a new technique, quantitative digital subtraction angiography (qDSA), to measure blood flow during liver embolization procedures. Liver embolization is a way of treating liver tumors by blocking blood flow to it. The qDSA technique could help doctors ensure the blood flow to the tumor is decreased by the right amount by calculating blood flow before, during, and after the procedure. Up to 20 participants will be enrolled for 1 study visit and data collection for up to 6 months.
