AbstractID: 10052 Title: Cardiac applications of dual energy CT, calcium scoring and
perfusion studies
Cardiac computed tomography (CT) has experienced a dramatic increase in clinical
use over the past decade. Facilitating that rise in use have been numerous advances
in CT technology – especially multi-slice and helical CT and decreases in gantry rotation
times. More recent advances have allowed for significant reductions in radiation dose
to the patient and the rebirth of dual energy imaging.
Dual energy CT (the simultaneous acquisition of images at two X-ray tube voltages) has
shown potential in its early usage to image myocardial perfusion much like a cardiac
SPECT exam. This single scan pairs functional information with the anatomic imaging of
CT coronary angiography at minimal cost of increased dose. Other promising dual
energy cardiac CT applications include plaque characterization, iron imaging, and
contrast enhanced calcium scoring.
This lecture will provide an overview of recent advances in cardiac CT including 4-D
imaging, calcium scoring, dose reduction strategies, and with a focus on dual energy
CT applications.
