qDSA Blood Flow Measurement in Patients Undergoing TAE of the Liver
Sponsor: University of Wisconsin, Madison
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.

Interventions
qDSA Blood Flow Measurement
Pre-, mid-, and post-embolization, qDSA and transabdominal US Doppler images will be acquired for research purposes during TAE and TACE procedures. For patients undergoing radioembolization, qDSA and US Doppler images will be acquired during both the preparatory angiogram and therapy angiogram (prior to delivery of the radioactive particles)
