CT Technology Update: The Cutting Edge


08:30 AM – 10:00 AM


Martin H. K. Hoffmann, MD, Marc Dewey, MD, U. Joseph Schoepf, MD, and Jonathan Avrom Leipsic, MD

Code: RC503


This session has four sections. First is 256-Section of the Heart, which discusses appropriate acquisition protocols for performing coronary angiography utilizing 8cm detectors. It also highlights appropriate rest periods for image reconstruction at various heart rates. Attendees will recognize the potential of prospectively gated axial acquisition protocols to reduce dose exposure. They will also recognize the clinical potential of combined morphology and perfusion scanning. This section identifies the different strategies of development in cardiac CT technology. The second section is Cardiac Volume CT with 320 Sections, which discusses the wide-area detector design of the 320-row CT scanner which images the body in a cylindrical fashion. Attendees will understand the technical implications and potential clinical applications of this new CT design.

Third section, Dual-Source CT of the Heart, discusses appropriate image acquisition protocols for performing dual-source CT coronary angiography. It highlights the importance of temporal resolution for imaging patients at high and irregular heart rates. Attendees will recognize the potential of dual-energy CT imaging for the assessment of myocardial ischemia. This section also discusses future developments in cardiac CT technology. The fourth section is Advancements in High Definition Coronary CT Angiography. It reviews recent technological advances with High Definition Coronary CT Angiography. This section also reviews the risks and controversies regarding cardiac CT radiation dose. It discusses iterative reconstruction for CCTA and in particular adaptive statistical iterative reconstruction (ASIR). Attendees will understand the principles of dual energy imaging and its clinical applications. They will also get updates on the recent advances in prospective triggering.
