Non-contrast CT synthesis using patch-based cycle-consistent generative adversarial network (Cycle-GAN) for radiomics and deep learning in the era of COVID-19 Reza Kalantar, Sumeet Hindocha, Benjamin Hunter, Bhupinder Sharma, Nasir Khan, Dow-Mu Koh, Merina Ahmed, Eric O. Aboagye, ...
Non-contrast computed tomography (CT), routinely performed for clinical indications, offers the potential for large-scale screening, however, identification of PDAC using non-contrast CT has long been considered impossible. Here, we develop a deep learning approach, pancreatic cancer detection with ...

This presentation explores clinical indications, limitations, and the scientific rationale for use of gadolinium contrast agents in MR imaging of the brain and spine. Enhancement of abnormal CNS tissues is related to structure and function of the blood-brain barrier under pathologic conditions, the pro...

This study aimed to evaluate a deep learning model for generating synthetic contrast-enhanced CT (sCECT) from non-contrast chest CT (NCCT). A deep learning model was applied to generate sCECT from NCCT. We collected three separate data sets, the developm
