Summary

The utility of Ultra High-Resolution Computed Tomography (UHR-CT) compared to conventional CT in all-comers (i.e., a generally lower-risk population) remains uncertain but is an important area of study in order to justify wider spread implementation and use of this technology, particularly in light of reports of significantly higher radiation exposure with UHR-CT, as well as longer scan times. The availability of technology to reconstruct conventional resolution (CR) simulation images from the raw CT acquisition data acquired on the UHR-CT scanner offers a unique platform to study this question without subjecting individuals to two different scans. The primary objective of this study is to generate preliminary data in support of the hypothesis that noninvasive UHR-CT is superior to conventional resolution CT for identifying patients with obstructive CHD.

Conditions

• Coronary Heart Disease (CHD)

Interventions

Type	Name	Description
DEVICE	Aquilion Precision	Ultra-High Resolution CT (UHR CT) capable of resolving anatomy as small as 150 microns, providing CT image quality with resolution typically seen only in cath labs. The UHR detector is newly designed to provide more than twice the resolution when compared with today's CT technology, with an all-new detector as well as tube, gantry and reconstruction technologies.
DEVICE	Conventional Computed Tomography	Conventional reconstruction Computed Tomography (CT) represents a pivotal approach in medical imaging.
