qDSA Blood Flow Measurement in Patients Undergoing TAE of the Liver
NCT06971991 · View on ClinicalTrials.gov ↗
Study 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 transarterial 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06971991
The ClinicalTrials.gov registry entry for NCT06971991 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 20 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Wisconsin, Madison, which has 943 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Transarterial Embolism appearing as the primary indexed condition, and to 1 intervention — of which qDSA Blood Flow Measurement is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06971991 reports 1 study location spanning 1 distinct geographic area — top geographies include Wisconsin. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
