1. To present and discuss current technological advances in CT, with major impact on clinical imaging, including specifically scan speed, dual energy and dual source, iterative reconstruction, low kV techniques, and perfusion imaging. 2. To detail for the radiologist the clinical impact of each advance, providing guidance in terms of utility and day to day clinical implementation, with attention to radiation dose reduction.

The exhibit will focus on six major areas, using primarily diagrams and images to convey the topics therein in an easily understood format. (1) Scan speed (and pitch) will be examined in the context of developments permitting imaging of the heart in one beat (wide area detectors, dual source), pediatric imaging without sedation, non-breath-hold imaging, and trauma. (2) Dual energy and dual source will be discussed, including two important applications, material decomposition and metal artifact reduction. (3) Iterative reconstruction will be reviewed, specifically the different existent approaches, reconstruction time, image quality, and image noise. The last three topics include (4) low kV, (5) perfusion imaging, and (6) dose reduction (including tube current modulation). A short summary will address future developments, including specifically technology translation to low- and mid-range cost systems.
