Abdominal applications of a novel detector-based spectral CT

Detector-based spectral CT (SDCT) is a recently introduced technology which uses a single x-ray tube and two layers of detectors to simultaneously collect low and high energy data. In this article, we provide an overview of this novel SDCT technology in abdominal imaging. Several applications of SDC...

Summary:Detector-based spectral CT (SDCT) is a recently introduced technology which uses a single x-ray tube and two layers of detectors to simultaneously collect low and high energy data. In this article, we provide an overview of this novel SDCT technology in abdominal imaging. Several applications of SDCT in abdominal imaging are discussed and illustrated, along with a brief description of current literature on the status of dual-energy CT in these applications. This includes urinary stone composition, characterization of masses (renal, adrenal, hepatic, others), tumor perfusion, improving vascular contrast, improving lesion conspicuity, decreasing artifacts and radiation dose savings using virtual non contrast.
