Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is intended to collect clinical feasibility data using this prototype research mode for the purposes of understanding potential clinical impact, potential limitations and strengths, and to further develop the technique through development of image reconstruction and processing approaches or identification of other areas of development required.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Up to 38 subjects may be enrolled to achieve the target number of 30 evaluable subjects. Withdrawn or discontinued subjects who are enrolled and received the investigational scan, may be replaced. Subject participation will be deemed complete once the diagnostic and investigational scans are completed. A subject is considered evaluable when images and raw data from the diagnostic single energy cardiac CT scan and raw data from the investigational dual energy cardiac CT scan have been collected successfully and demonstrate a diagnostic interpretation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Coronary CTA

After the subject undergoes the standard of care, clinically indicated cardiac CT scan for diagnostic purposes, the investigational scan using the GSI Cardiac Scan Mode will be conducted utilizing the same contrast administration.

Additional Gemstone Spectral Imaging (GSI) cardiac scan

Intervention Type DEVICE

After the subject undergoes the clinically prescribed cardiac Computed Tomography (CT) scan for their diagnostic purposes, the investigational Gemstone Spectral Imaging (GSI) scan will be conducted following the diagnostic CT scan utilizing the same contrast administration.
