CT TAVR Abdomen Study
Dual Energy CT Decreased IV Contrast Dose Imaging for TAVR
University of Maryland, Baltimore
164 participants
Sep 19, 2023
INTERVENTIONAL
Conditions
Summary
A standard polyenergetic CT (computed tomography) procedure utilizes 100 ml of iodinated contrast. A recent world-wide shortage of iodine based intravenous contrast has highlighted the need to search for alternative methods or doses. Reducing iodinated IV contrast dose can mitigate IV contrast supply shortages and enable significant cost savings for the radiology practice and hospital system. In addition, decreased IV contrast dose can potentially reduce the rate of acute kidney injury, specifically in patients with decreased renal function. The purpose of the study is to determine whether low IV contrast dose CT with monoenergetic reconstruction can be use for presurgical planning of transcatheter valve replacement (TAVR) procedure.

Interventions
Standard dosage of Omnipaque for CT imaging is 100 ml. Cohort will be given a reduced dosage.
Dual energy CT scanners enable monoenergetic CT image reconstruction which allows for improved iodine image contrast.
