Sentence examples for multiple contrast agents from inspiring English sources

Overall, these in vitro studies suggest an imaging framework for future in vivo MRI studies to simultaneously quantify multiple contrast agents.

Clinical use of these contrast-enhanced MRI scans has further expanded as multiple contrast agents have been approved for specific clinical imaging applications (e.g., blood pool contrast agents4, hepatobiliary contrast agents5).

For this method, a pressure vessel suitable for neutron radiography was designed and fabricated, modifications to imaging instrument setups were tested, multiple contrast agents were tested, and algorithms developed for tracking of flow.
