A Study to Evaluate Low Dose Chest CT vs. Standard CT in Cystic Fibrosis Patients

Overview

About this study

The purpose of this study is to determine the lowest radiation dose that allows interpretation of chest CT scan.

Our group developed a novel chest CT technology with reduced radiation exposure and procedure duration. This is a new dose optimization and efficiency technology and a tin filter, which greatly reduce the radiation dose compared to a standard chest CT. The procedure is fast and can be performed without sedation. We therefore aim to validate this promising technology as an alternative clinical monitoring tool against current standard-of-care with CXR.
