This study is looking at a new way to perform CT scans for people who need a TAVR (Transcatheter Aortic Valve Replacement) procedure. Researchers are testing if using a lower dose of Omnipaque, an iodinated contrast agent, with a special type of CT scanner called Dual Energy CT, can still provide clear images. This is important because there have been shortages of contrast agents, and using less might also reduce the risk of kidney problems. The study aims to see if these lower-dose images are good enough for planning your TAVR procedure. You can join if you are between 18 and 88 years old and are scheduled for a TAVR abdominal CT scan. The study will measure the quality of the images over 18-24 months.

Study design
