Check out our recently published paper. @benWTmd @Samei @DukeCVIT @DukeRadiology
🚀 Exciting new study explores Photon-Counting CT (PCD-CT) for detecting liver lesions. Is it better than energy-integrating detector CT (EID-CT)? Let's discover the results! pubs.rsna.org/doi/10.1148/ra… 👇 #RadInTraining #Tweetorial @RITEditor
