This study will test a new image reconstruction algorithm called Precise Image in 168 children aged 18 months to 18 years undergoing CT scans. The goal is to see if it produces images as good as or better than the current standard. If it works, it could lead to clearer scans for …

This study tests a new computer method called P-MAR that helps reduce the blur or streaks metal objects (like implants or fillings) cause in CT scans. About 120 adults with metal in their body will get standard CT scans, and the new method will be compared to existing techniques.…

This study tests a new image reconstruction software called Precise Image for CT scans of the shoulder, hip, and knee in adults. Researchers want to see if it produces images as good as or better than the current standard software. About 84 adults will have their existing CT scan…

This study tests a new image-reconstruction method called Precise Image on CT scans taken during medical procedures like needle or probe placement. Researchers want to see if it gives doctors clearer pictures than the current standard. About 55 adults will have their existing CT …

This study will look at 2000 adults who had a heart CT scan to find unexpected health issues outside the heart, such as lung problems or blood vessel abnormalities. The goal is to understand how often these surprise findings occur. No treatment is given; it is purely an observati…

This study will test a new software feature called Precise 3D Surview on two types of CT scanners. The goal is to see if the software can automatically plan scan areas as well as experienced CT technologists can by hand. About 274 adults getting routine non-contrast CT scans will…

This study looks at whether getting a CT scan sooner after a person's heart stops outside the hospital and is revived can help them live longer. Researchers will review records from 5,000 adults treated at six hospitals in Taiwan. The goal is to find the best timing for CT scans …
