CT TAVR Abdomen Study

$125,000 Award

Project Overview

Decreasing iodine-based intravenous contrast has helped alleviate supply shortages and benefits both patients and imaging providers. This project seeks to obtain diagnostic quality dual energy CT abdomen TAVR studies at <50% reduced dose of IV contrast in >90% of patient images. The team hopes to achieve this by imaging patients with 1/3 to 1/4 of the conventional dose of IV contrast combined with dual energy image reconstruction algorithms.

Midpoint Progress Updates – October 2023

The team began the recruitment of participants after gaining IRB approval in the last week of August. Following recruitment, two patients have been successfully scanned with a 1/3 dose of contrast agent which delivered quality diagnostic images. Pending results (images of diagnostic quality) of greater than 60% of the first ten patients, they plan to scan an additional 72 patients with the same parameters to make up the first cohort.
