Study Summary
Using an investigational CT scanner which uses a new type of detector to capture X-rays, (a photon counting CT detector), the goal of this experimental study is to compare conventional CT images to CT images using the photon counting detector in patients undergoing CT scans for clinically indicated reasons. The main question it aims to answer is whether the images produced using the new detectors are superior in quality. Participants will undergo the clinically indicated CT images and the photon counting detector CT images of a limited area during the same examination time.
Primary Outcome
Mean difference in relative image quality grading of CT images using Photon counting detectors vs. conventional detectors in group of patients with various clinical conditions. Scale name "Visual grading analysis (VGA)" . Expert radiologist observers compare the relative grades of the images from the PCCT to the grades of the same patient's reference images from conventional CT acquired at the same time. The visual grading scale incorporates technical factors in the acquisition and image display
