This study compares a 1-hour versus a 4-hour intravenous premedication regimen to prevent allergic reactions to CT contrast dye in emergency patients with a known allergy. About 540 adults with a documented contrast allergy who need an urgent CT scan will be randomly assigned to …

This study tests a new image-reconstruction method called Precise Image on CT scans taken during medical procedures like needle biopsies or screw placements. Researchers want to see if it gives doctors clearer images to guide these procedures compared to the current standard. Abo…

This study tests a new 3D imaging feature on CT scanners to see if it can automatically plan scans as well as expert technologists. About 274 adults will have a standard CT scan, and the tool's suggestions will be compared to manual planning. The goal is to see if the tool can sa…

This study looks at 5000 adults who had a heart attack outside the hospital and were revived. Researchers want to see if getting a CT scan sooner helps people live longer. They will review past medical records to find patterns.

This study tests a new computer method called P-MAR that reduces metal-related distortions in CT scans. Researchers will compare P-MAR to standard scans and an older method (O-MAR) in 120 adults with metal implants or dental work. The goal is to see if P-MAR makes images clearer …

This study will look at 2000 adults who had a heart CT scan to see how often doctors find unexpected health issues like lung problems or blood vessel abnormalities. The goal is to understand what else these scans can detect beyond heart disease. No treatment is given; it is purel…

This study tests a new image reconstruction algorithm called Precise Image in children aged 18 months to 18 years who need a head or body CT scan. The goal is to see if the new method produces images as good as the current standard. About 168 children will take part, and their sc…

This study tests a new image reconstruction algorithm called Precise Image for CT scans of the shoulder, hip, and knee in adults. Researchers want to see if it produces clearer images and gives doctors more confidence in their diagnoses compared to the current standard method. Ab…
